• MICROTREMOR MEASUREMENT SURVEY AND NATURAL FREQUENCY ESTIMATION IN THREE-STORY STEEL FRAME STRUCTURE HOUSE

  NISHII Yasuma, KONDO Takahito, MUKAI Yoichi, NABESHIMA Kunihiko

  In this study, the authors conducted a microtremor measurement on 15 three-story steel-frame houses and investigated their natural frequencies and damping ratios. Additionally, the authors propose a new method for estimating the natural frequencies of steel-frame houses at the newly constructed state. The proposed method is an evaluation method that does not require modeling based on structural design process, and the validity of the estimated natural frequency which was obtained using this method was verified.

• Typology on exterior design of townhouses in a World Cultural Heritage Site of a Nepali City

  Asuka Hamaoka, Naohiko Yamamoto, Tetsuya Yoshida, Anri Miyauchi, Masaya Masui, Yoichi Mukai

  Abstract The paper deals with the exterior design of townhouses in an urban block of the eastern part of Bhaktapur in Kathmandu Valley. The primary purpose is to provide an analysis method to determine the typical combination among exterior design components of Nepalese townhouses. By using multiple correspondence analysis and cluster analysis, 118 samples are grouped into 13 clusters. Secondly, all the clustered samples were put onto the original plots on the map to see the characteristics of their locations. Such a process would help a designer/planner reflect on how they should compose a proper facade in reconstruction works of townhouses after the earthquake in 2015.

• Exterior design of townhouse and their extension/reconstruction process with regard to eaves types in a World Cultural Heritage site of a Nepali city

  Naohiko Yamamoto, Kayo Takahashi, Masaya Masui, Anri Miyauchi, Yoichi Mukai

  Abstract The paper deals with the exterior design of townhouses both inside and outside the Historic Monument Zone in the eastern part of Bhaktapur of Kathmandu Valley inscribed on the World Cultural Heritage List in 1979. This paper consists of following steps. First, the authors compose the original format of the survey sheet for Nepali townhouses. Second, the paper hypothesizes that a townhouse either experienced an extension of the upper floors or was totally reconstructed in the course of time. The authors propose “eaves types” as the key idea in this hypothesis. The result of the exterior design survey is primarily compared between inside and outside the Historic Monument Zone of the World Cultural Heritage site. Further comparison among eaves group or eaves types is done. Finally, eaves types are confirmed with the floor extension/reconstruction period demarcated by past devastating earthquakes. The result of the comparison again very well explained the characteristics of each eaves type.

• Investigation of microtremors observed at historic masonry townhouse buildings after Nepal earthquake

  Yoichi Mukai, Hayato Hoshino, Naohiko Yamamoto, Masaya Masui, Anri Miyauchi, Ram Prasad Suwal

  The Gorkha earthquake in 2015 was a recent large-scale earthquake that caused severe damage to many historic masonry buildings in the Kathmandu Valley, Nepal. The authors conducted a visual inspection survey of seismically damaged buildings after the earthquake in the historic town district of Bhaktapur in the Kathmandu Valley. The first part of this paper reports the distribution of the historic masonry buildings for each damage level in the surveyed area. A concentrating zone of severely-damaged buildings was explicitly found in the damage-level distribution map. Almost half of all the surveyed buildings were severely damaged during the earthquake, and most of these were historic masonry townhouse buildings. In the second part, the ambient vibration characteristics of the conventional historic masonry buildings in Bhaktapur are investigated. Typical dwelling houses in a historic town district in Nepal, which generally formed terraced houses built around a courtyard, were targeted for the measurement. Thus, the influence of adjacent buildings, which makes it difficult to identify the predominant natural frequencies from building vibration measurements, was also observed. Microtremor measurements using two accelerometers were conducted at 11 historic masonry buildings to investigate the discrimination degree for identifying the predominant natural frequency of conventional townhouse buildings. The estimated primary natural frequencies of these buildings were compared with the results of the screening model analysis. The advantages of using the proposed screening model analysis to improve the uncertainty of the first natural frequency identification by the microtremor measurement are discussed. Additional measurements of the microtremors at 4 of the 11 measured buildings were conducted using a different location combination of the two acceleration sensors. The sensors were placed between two different floors, and the transfer functions of each floor were investigated to observe the predominant vibration components on the floors in the entire building. Moreover, the coherence values observing the in-plane correlation of the floor responses were also analyzed for the dataset measured at two points separated on the same floor. Finally, an effective method for measuring the microtremors is discussed to improve the assessment of the vibration characteristics of conventional historic masonry buildings in Nepal.

• Three-dimensional printing of locally bendable short carbon fiber reinforced polymer composites

  Masahito Ueda, Yuuki Watanabe, Yoichi Mukai, Nobuhisa Katsumata

  Locally bendable solid plates were manufactured in a single 3D-printing operation, using a single material, i.e., short carbon fiber reinforced plastic (CFRP). The locally bendable CFRP plates included solid and bendable parts, which were connected seamlessly using double-stepped lap configuration. A parallel cross shape structure and 100% infill structure was adopted for the bendable and solid parts, respectively. The bendability could be controlled by varying the girder angle of the parallel cross shape structure. The bending stiffness was reduced to nearly 98% compared to that of the solid plate. The cyclic bending tests indicated that the locally bendable CFRP plate underwent reversible bending deformation. The bending stiffness decreased by approximately 8–14%. However, visible damage was not observed even after 100 cycles of bending deformation.

• A Study on Vertical Division on Façade of Townhouses at the Time of Inheritance - The case study on Bhaktapur world cultural heritage site in Nepal

  Funahashi Tomomi, Masui Masaya, Yamamoto Naohiko, Mukai Yoichi, Pant Mohan

  In Nepali historic cities, it is commonly seen that a façade of a townhouse is vertically divided at the time of inheritance, which causes damages on traditional façade corruption as well as structural vulnerability. While it has been inside the framework of traditional transition, the cases of new construction of divided parts have been accelerated in the process of reconstruction after the 2015 earthquake and resulted the rapid transition of townscapes. This paper discusses the challenges of this issue based on the survey of the specific area in Bhaktapur and reveals that styles of façade design have been influenced by division system; façade division is closely related to interior one: the on-going building regulation does not manage this issue and requested to compile this issue.

• TYPOLOGY ON EXTERIOR DESIGN OF TOWNHOUSES IN A WORLD CULTURAL HERITAGE SITE OF A NEPALI CITY:The case study on an urban block in the eastern part of Bhaktapur

  HAMAOKA Asuka, YAMAMOTO Naohiko, YOSHIDA Tetsuya, MIYAUCHI Anri, MASUI Masaya, MUKAI Yoichi

   The paper deals with the exterior design of townhouses in an urban block of the eastern part of Bhaktapur in Kathmandu Valley registered as a World Cultural Heritage site in 1979. The paper consists of following five steps.
   1) First and the most important purpose is to provide analysis method to determine typical combination among exterior design elements of Nepali townhouses. By adopting the Multiple Correspondence Analysis (or Mathematical Quantification Theory Category III is equivalent also) and Cluster Analysis, 118 samples are grouped into 13 clusters.
   2) Secondly, in the preceding paper, authors proposed the idea called "eaves types". It was meant to discern the developing process of Nepali townhouses between extension of storeys and total reconstruction. Although we showed the pitched eaves types and flat eaves experience different development, we had not yet reached to describe the concrete facade classification of eaves types. The paper tries to present variation of exterior design of eaves types.
   3) Several clusters derived from analysis show different characteristics of facade though sometimes they belong to the same eaves type. For 3F, 4F pitched eaves type and 3F, 4F flat eaves type, the analysis results in finding both traditional sophisticated design and contemporary one. What's more, cluster 8 regarded as one with the most traditional style contains both typical old townhouses and newly rebuilt guesthouse-like ones. This may suggest that recent exterior design of guesthouses are similar to that of traditional townhouses
   4) Every cluster properly corresponds to the structure excluded from item-category type data. Clusters with flat eaves correspond chiefly to confined masonry followed by mixed structure with masonry and RCC slabs. As for affected condition by 2015 earthquake, all the three clusters within 3F no eaves type came under the category "partially destroyed".
   5) Finally after clustering, all samples were put into the original plots on the map. Facades of townhouses along streets tend to maintain traditional exterior design elements as opposed to the facades inside courtyards, which would normally take on modest external appearance. There are also several variations of facades ranging somewhere between traditional and simple modern exterior design. Townhouses with such marginal designs are scattered along streets, in alleys and inside courtyards.
   In this way, most of clusters can be related to certain locations in correspondence with their exterior designs. This would help a designer/ planner to reflect how they should compose a proper facade once they get involved in reconstruction works of townhouses after the earthquake.

  YAMAMOTO Naohiko, TAKAHASHI Kayo, MASUI Masaya, MIYAUCHI Anri, MUKAI Yoichi

   The paper deals with the exterior design of town houses both inside and outside monument zone of the eastern part of Bhaktapur in Kathmandu Valley registered as a World Cultural Heritage site in 1979. This paper consists of following four steps.
   1) Firstly, authors composed the original format of survey sheet for Nepali town houses. The categories of this sheet are grouped into four items, which are frame, silhouette, part and element, each of which contains more detailed categories. The survey sheet was completely made from scratch with reference to the several important existing researches. The number of samples are 104 buildings inside Monument Zone (core + buffer zone) of World Cultural Heritage and 73 buildings outside Monument Zone. More than 90 % of the total sample buildings are classified as townhouses.
   2) Secondly, the paper tries to submit a hypothesis on that either a town house experienced the extension of the upper floors or totally reconstructed during the course of time. Authors propose ‘eaves types’ as the key idea in this hypothesis. Eaves types are classified into 8 types depending on which floor level eaves are attached to. Eaves types are classified into three upper level groupings, i.e. pitched eaves group, flat eaves group and without eaves group. As for structure, pitched eaves group are basically masonry construction as opposed to the RCC construction (confined masonry) or mixed structure (masonry wall + RCC beams, masonry + RCC rooftop) for flat eaves group. In addition, three-storey buildings of without eaves group turned out to be masonry construction and four-storey buildings of the same group chiefly consist of RCC construction. The former eaves type shows similar characteristic to pitched eaves group. So does the latter to flat eaves group.
   Regarding the relations among eaves types, the paper made an attempt to establish a diagram that explains the transition among important eaves types whether an eaves type is reconstructed or just upper floors are extended.
   3) Result of the exterior design survey is primarily compared between inside and outside Monument zone of world cultural heritage. Further analysis is conducted by two levels as needed, i.e. comparison among eaves group and that among eaves types. The items to be examined here are frontage, roof shapes, roofing materials, finishing on the first floor wall, openings on the first floor as well as on the third floor, wood carving, window lattice and cornice between the second and the third floor. The result turned out show distinct characteristics among eaves types or eaves groups that led authors to provisional proof of the hypothesis with eaves types.
   4) Eaves types are finally confirmed with the construction period and upper floor extension period. In Nepal, for the past one century, prior to Nepal-Gorkha earthquake in April 2015 earthquake, two devastating earthquakes happened. They are Bihal-Nepal Earthquake in January 1934 and India-Nepal border region earthquake in August 1988. These years are applied to separation of periods for recovery from the disaster was the chances to reconstruct the affected buildings. The result of the comparison of reconstruction/extension periods with eaves types again very well explained the characteristics of each eaves type.

• PLANNING TYPOLOGY OF URBAN DWELLINGS AND THEIR DEVELOPMENT PROCESS FOUND WITHIN A VOTARY AREA TO THE HOUSE GUARDIAN DEITY AND DISTRIBUTION OF INHABITANTS' SURNAME:A study on the socio-spatial structure and urban tissue in Bhaktapur, Nepal Part2

  MIYAUCHI Anri, YAMAMOTO Naohiko, MASUI Masaya, PANT Mohan, MUKAI Yoichi

   This paper aims to discuss fundamental units forming urban settlement blocks and their development process which demarcate urban fabric with respect to the combination arrangement of urban dwellings types. Bhaktapur is known as one of the historic cities of the World Heritage Site in Kathmandu Valley. The analysis focuses on the house distributions that have common votary areas of the house guardian deity called chetrapatra and the aerial extent of the same surname (thar). Considering these into account, the authors classified urban dwellings into 9 types. We try to submit a hypothesis on the development process of planning type clusters of urban dwellings as fundamental units forming urban settlement blocks.
   chetrapatra is an iconic ritual artifact made of stone slab carved in a form of eight-pealed lotus, and it is placed in front of a house entrance or in a courtyard. People worship this stone when they go out to the street from their house or a lane. There are also cases when this type of chetrapatra is common to inhabitants who go in and out at the lane. We classify chetrapatras into 7 types based on ownership and locations. The areal extent for worship to chetrapatra is sub-divisions in the areal extent for worship to Ganesh shrine. But they must be owned respectively on either side of the street.
   The Newar population may be classified into various social status according to the traditional profession, caste, or other form of socio-religious associations. In Bhaktapur, their social status are divided into 3 categories. These are the Macrostatus system, thar and phuki. as proposed by Levy (1990). We conducted survey on the distribution of thar for our analysis to have information of kinship. We found five areal extent of a same thar in the case-study area. They all spread the both side of street but have the different plot depth perpendicular to the street.
   Next we classify urban dwellings into 9 types whether they have a common chetrapatrs or individual one and their locations, which we call ‘Planning Types of Urban Dwellings’. It should be noted that ‘Courtyard Dwelling Units’ is relatively old compared to the other types of urban dwelling units. In addition, this type has one common chetrapatra shared by all the residences surrounding the same courtyard. chetrapatra is placed in front of the entrance of a ‘Courtyard Dwelling Units’. On the other hand, ‘Detached houses facing the street’ tend to have their own chetrapatra.
   Finally, we analyze the distribution of ‘Planning Type Clusters of Urban Dwellings’ in the case-study area. The analysis indicated dominant arrangement patterns which are the one that include ‘Courtyard Dwelling Units’ on one side of the street and ‘Detached houses facing the street on the other side. Taking that into account, we found the particular arrangement patterns of ‘Planning Type clusters of Urban Dwellings’ developed across the street. Another important arrangement pattern is the one that ‘Incomplete Courtyard Dwelling Units’ often found on the plot backside of ‘Detached houses facing the street’. We regard them as two important typical cluster types of urban dwelling units. We suggest that the development process of such cluster types underwent 3 stages, giving great influence to the urban development in the earlier period.

• Detailed FEM analysis for full scale steel structure considering fracture of beam ends

  Yasunori Mizushima, Yoichi Mukai, Tomoharu Saruwatari

  © 2017 National Technical University of Athens. All rights reserved. This paper reports a non-linear analysis of a steel structure using a large-scale and detailed finite element model considering fracture phenomenon. The shaking-table test results of a 3-story full-scale steel frame structure, which were carried out at E-defense in 2013, are evaluated analytically in this paper. The analytical model used in this study is intended to replicate adequately entire shape of target steel frame structure specimen, assembling huge numbers of tiny finite elements. The damage index is introduced as the fracture criterion on steel members model for execution of FE simulations. Elements whose damage index has been reached to 1.0 are eliminated in our way of FEM analyses. The damage index shows a good correlation with the occurrence of the fracture observed in the experimental test. The timing of the first fracture of the beam end in the analysis mostly match well to that of the experiment. In addition, the structural responses obtained by the analysis agree with those of the experiment.

• Response reduction methods for base isolated buildings with collision to retaining walls

  Akiko Kishida, Nao Nishimura, Yuki Yamashita, Kenzo Taga, Hideo Fujitani, Yoichi Mukai

  This paper proposes a new damper that can change the damping force depending on the response displacement and response velocity. The proposed damper reduces the damage of seismic-isolated structures which undergo excessive deformation during huge earthquakes, without lowering the performance of the seismic-isolation system during medium to small magnitude earthquakes. We investigate the effects of using the proposed attenuator on the responses of a superstructure model to seismic motion that causes collision with retaining walls. An experiment using a shaking table is conducted, and the results from the test are compared with those from numerical analyses. The test results agree approximately with the numerical analysis results except for the absolute acceleration results in collision cases.

• COMPARISON OF THE DISTRIBUTION OF HOUSEHOLDS WITH REGARD TO WORSHIPPING THE SAME SHRINES OR CROSSINGS, AND THEIR CORRESPONDENCE TO THE AREAL EXTENT OF TOL:A study on the socio-spatial structure and urban tissue in Bhaktapur, Nepal Part1

  MIYAUCHI Anri, YAMAMOTO Naohiko, MASUI Masaya, TANAKA Mari, PANT Mohan, HAMAOKA Asuka, MUKAI Yoichi

   This paper aims to discuss the areal extent and spatial structure of neighborhood, called tol, which possibly demarcate urban fabric with respect to worship and funeral procedure. Bhaktapur is known as one of the historic cities of the World Heritage Site in Kathmandu Valley. The analysis focuses on the house distributions that have the common votary area of the guardian deities' shrine and the use of the same crossing for funeral procedure.
   A tol is one of the traditional neighborhood units. But it is not clear how tols are structured and what tols have in common. First, we take a look into the existing studies on origin and outline of a tol, and pay special attention to the following two studies. A research done by Pant (2001) has taken the approach that the key to consider a tol is the areal extent of worship to the guardian deities, ganesh. Another research done by Gutschow (1975) has claimed that the clue to determine tol boundaries is the ways of the Dead to crematories. It consider a tol as equivalent to the areal extent of use of the same chwasa which is a stone found often at the crossings on the way to crematories from the diseased houses.
   Ganesh is often considered as a guardian deity at various neighborhood levels. That of a tol is called Tol Ganesh. A Tol Ganesh is normally placed on the main square in a tol, except when there is a presence of a more prominent deity of wider importance in the main square. People in the same tol usually worship the same Tol Ganesh. We find out that those living urban dwellings in located on both sides of a street worship to the same Tol Ganesh, but the depth of its areal extent on one side of a street seems shallow than the other side.
   Chwasa is an aniconic ritual artifact made of a single stone placed on the crossing. Various articles left by the diseased are disposed on the stone as a part of the funeral procedures, for example clothes, umbilical cord or inauspicious belongings of the dead. We found 7 chwasas in the case-study area to the east of Dattatraya square. However the inhabitants in the peripheral part of the old city do not use these chwasas but use the temples or the crematories outside the city area. People living in the midst of the city area after disposing articles of the dead on chvasa also use the temples afterwards.
   Next we compare the areal extent of worship to Tol Ganesh with that of use of chwasa. Whether or not a ganesh shrine and chwasa are closely placed will determines overlapping extent of both votary areas. However it became clear that the areal extent of use of chwasa have the same character with that of worship to Tol Ganesh in terms of Ryogawa-cho structure explained below and the difference in horizontal depth perpendicular to the street.
   Finally, our suevey located tol boundaries in the eastern part of Bhaktapur. It turned out that there were 2 types of tol boundaries. i.e. the more common type whose boundaries lying on the backside of houses (Ryogawa-cho type), and the other one with boundaries lying on the street (Katagawa-cho type). Compering these three boundaries, (Tol Ganesh, chwasa and tol), Katagawa-cho type tol boundaries seem to be an exception. But we will try to find particular meaning in them in the next paper on historic urban formation.

• Investigation of Damage in and Around Kathmandu Valley Related to the 2015 Gorkha, Nepal Earthquake and Beyond

  Tsuneo Ohsumi, Yoichi Mukai, Hideo Fujitani

  An earthquake with a magnitude of 7.8 (Mw) occurred at 11:56 NST (local time) on 25 April 2015, in the central part of Nepal (Gorkha).We organized a damage survey team and dispatched it to the affected area for several periods following the earthquake (May 26 to June 3: first trip, June 17 to 24: second trip, August 16 to 21: third trip and October 27 to November 2: forth trip) to investigate the damage and collect data. We found traditional construction methods are stronger than imagined. Many traditional earthquake-resistance technologies exist in Nepal. The first and second surveys were to collect timely statistical information on the damage to brick and stone masonry buildings and to confirm the availability of data and their sources for subsequent surveys. We also carried out a first-hand building damage survey in selected areas. The investigation of the strong-motion data set from the USGS Center for Engineering Strong Motion Data includes information from stations in Nepal that continued to function throughout the main shock and the several subsequent strong aftershocks of the 2015 earthquake. The third and fourth surveys were to collect the every building damage survey in selected areas. The motivation behind the survey was to obtain ground truth data for the calibration and improvement of a wide-area damage estimation system that uses satellite data the system is currently under development by National Research Institute for Earth Science and Disaster Prevention (NEID) and the Japan Aerospace Exploration Agency (JAXA). A survey of the degree of damage was conducted for every house in Sankhu and Khokana by the European Macroseismic Scale (EMS) -98. This report outlines the findings of this investigation team into various aspects of the earthquake disaster in the Kathmandu Valley. The motivation behind the survey was to obtain ground truth data for the calibration and improvement of a wide-area damage estimation system that uses satellite data. Field surveys confirmed that the severely damaged urban area was well detected by the decrease derived from the ALOS-2 satellite SAR data. The higher classification accuracy for non-damaged area helps to detect the damaged urban area using this technique, immediately after a disaster.

  KENTARO HAMA, MUKAI YOICHI

  When we evaluate the structural characteristic of traditional wooden structures, it is useful way to estimate vibration characteristics from micro-tremor measured data. In this study, we conducted micro-tremor measurements and excitation tests on Chofuku-ji Hondo in Ikoma City, Nara pref. and estimated the natural frequency, the damping ratio, and so on. Moreover, we made the analysis model of the building, and made sure of the differences between analytic and measured values by eigenvalue analysis.

• Detailed FEM Analysis Considering the Excitation History for Full Scale Shaking Table Test Applying Multiple Times Seismic Excitations

  MIZUSHIMA Yasunori, MUKAI Yoichi, NAMBA Hisashi, TAGA Kenzo, SARUWATARI Tomoharu

  Recently, there have been some researches on analysis using finely-meshed FEM model to understand in detail the behaviors of buildings during severe earthquakes. The accuracy of such an analysis is often validated by comparing the analytical results with the corresponding full-scale shaking table test results. While they are highly successful in the accuracy, few take account of the sequence effect of multiple series of excitations, in the other words, the effect of inherent structural damage caused by prior excitations. In this paper, as a first step toward a design considering fore/aftershocks, numerical analysis using finely-meshed FEM model is conducted for a steel structure subjected to multiple series of excitations in a full-scale shaking table test. The FE model structure is modeled with planar and solid finite elements. It is shown that, by taking account of the history of input excitations and caused damages, the actual behaviors can be simulated by analysis with much higher accuracy.

• SUPER-DETAILED FEM SIMULATIONS FOR FULL SCALE STEEL STRUCTURE CAUSED FATAL RUPTURE AT ITS JOINT PARTS BETWEEN MEMBERS:Shaking table test of full scale steel frame structure to estimate influence of cumulative damage by multiple strong motion Part 1

  MIZUSHIMA Yasunori, MUKAI Yoichi, NAMBA Hisashi, TAGA Kenzo, SARUWATARI Tomoharu

   There have been some researches on analysis using finely-meshed FE model to understand in detail the behaviors of buildings during severe earthquakes. The accuracy of such analysis is often validated by comparing the results to the corresponding full-scale shaking table test. While they are highly successful in the accuracy, no researches take account of the effect of fracture of members. In this paper, numerical analysis isconducted for asteel structure subjected to multiple series of excitations in a full-scale shaking table test considering the fracture. The structure is modeled with planar and solid finite elements and the fracture is treated by mandatory deletion of elements at time when fracture was observed in the experiment. It is shown that, by considering fracture of steel members with deletion of elements the history of input excitations and caused damages, the behaviors can be simulated by analysis with much higher accuracy.

• A study on large-scale simulation of a 20-story steel building structure

  Yasunori Mizushima, Yoichi Mukai, Masahito Ohno, Tomoharu Saruwatari

  The differences in seismic responses in highly nonlinear ranges among various analytical models are not clear. These include such as frame models, and detailed Finite Element Method (FEM) models microscopically reproducing the individual components' shapes are not clear structures. In this study, the dynamic response of a detailed FEM model is compared to those of frame models. The FEM model was made to reproduce a building's shape as precisely as possible and analyzed by LS-DYNA that is commercial FE code equipped explicit method. The frame model was macroscopically composed of beam elements. Two frame models were considered; in one model, the P-delta effect was considered, and in the other model, it was neglected. The differences between those frame models and the detailed FEM model in highly non-linear ranges was investigated. As a result, it was assured that the frame model that neglected the P-delta effect tend to underestimate the deflection in these ranges, while the residual deflection of the frame model that considered the P-delta effect was larger than that of the detailed FEM model because of stiffness degradation.

  Takahiro Fujii, Hideo Fujitani, Yoichi Mukai

  This study elucidates a method to ascertain control variables such as the performance function and weight coefficient, at the initial stage of structural design. For the purpose, authors assess the structural properties (equivalent damping factor and equivalent natural circular frequency) of semi-active optimal control system by MR damper to evaluate the structure response. First, the relations between weight coefficient and those system properties are discussed. Secondly, control parameter determination in consideration in the maximum controlling force is proposed. Validity of those design proposals are investigated by real-time hybrid experiments and numerical simulations.

• Evaluative Study of Structural Properties By Microtremor Measurements of Traditional Wooden Structures Including Unoccupied Houses

  Yoichi Mukai, Erina Ogawa, Sonoe Akamine

  In this paper, microtremor measurements and on-the-spot investigations of anti-seismic efficiency are carried out at the traditional wooden housings including unoccupied houses located in Imai-Cho, Kashihara-City, Nara, Japan, one of a town built and prospered originally around a temple. This town, Imai-Cho has a lot of traditional wooden structures historically precious, most of those structures have been constructed since 18 or 19 century. Many structures in Imai-Cho are repaired and investigated to preserve to the next ages, on this purpose, in 1993, Imai-Cho has been specified as designated area of the important "Traditional Architectures Preservation District" in Japan. On the other hand of those conserving business, a lot of unoccupied houses are increasing in this area, and those houses are left to become their aging damages without repairs. In this study, to make assure structural properties for anti-seismic efficiencies, building weights and floor sizes, constructing year, natural periods and latent aseismic strength are investigated for various types of wooden houses in this town. Thorough those evaluations, it is found that natural periods in most of structures in this area could be indicated to the explicit interrelations with structural volumes or building ages.

• Evaluation of Repairing Effect under Bending Load for Wooden Beam Elements with Notches by Using Carbon Fiber Sheet

  Yoichi Mukai, Yumi Inada

  Partial repairing way of wooden frame elements with notch on the side loaded tension stress is investigated and experimental tests to assure reinforcing effect on the repairing part by using carbon fiber (CF) sheet is carried out. When the notches appear on the bottom edge of beams at reconstructing site of an existing wooden house and those beams with notches can not be removed or replaced, proposing repairing way will be considered to be usefully adopted. Cut-out area of beam is plugged up with wooden peace and covered by wooden plate on the bottom. Those wooden peace and plate are stuck on beams via adhesive layer and CF sheet is rolled up to the repairing part. Stress concentrations and deformations of the repaired and un-repaired beams with notch are calculated by comparison of parametric survey through FEM analyses. Proposing repairing way of wooden beam with notch is also experimentally examined by bending loaded tests. As a result, while notched beam is abruptly broken from the local position around the corner of notch, it is observed that CF sheet reinforced beam is splitted away at the plane covering whole section area, and also that mechanical property of the CF sheet reinforced beam was almost fully at stiffness and about 70% at strength of the non-lacked beam.

• SEISMIC PERFORMANCE OF OPTIMAL COUPLED TWO ADJACENT BUILDINGS

  Fuming ZHANG, Yoichi MUKAI

  The optimal allocation of damping in coupled buildings and its control efficiencies are discussed in this research. For a given total damping, the optimal connecting damping and connecting stiffness that result minimum magnification factors for stable vibrations are searched from numerical computation. It was found that allocation of total damping for connecting damping gives maximum control efficiencies when the total damping is smaller. While for larger total damping, the required connecting damping decreases, and more damping should be allocated within buildings. The efficiency of coupling decreases with the increase of total damping, and is defined by an equivalent damping factor. Using equivalent damping factor and equivalent vibration periods, earthquake response of the coupled buildings may be satisfactorily evaluated by response spectra of single degree freedom system.

  In this study, evaluation for seismic behaviors of inter-story isolated building structures and proposition of effective synthesis for inter-story isolating systems are focused. Emphases are put on following items: 1) To make assure fundamental characteristics of seismic responses of inter-story isolated buildings, 2) To estimate influences of aseismic behaviors of inter-story isolated buildings under considering soil-structure interactions. Through parametrically numerical simulations, those items are investigated in detail. As more advantageous idea to improve efficiency of inter-story isolating systems, additional installations of hysteretic damping devices are pointed out and estimated. As a result, it is assured that more effective response reductions can be gained by introducing the additional hysteretic devices on the lower stories below isolating floor.

  To propose optimum design shear force distridutions for high-ductility response controlled structures, numerical parametric studies are executed. Various cases of ductility factors, natural periods and inelastic stiffness of whole frames are evaluated to investigate for dispersions on characteristic of response shear force distributions. As a result, significant relations of each parameter to assemble optimum shear force distributions are confirmed. Moreover, by considering dispersions of shear force response, design shear force distributions are proposed to design effective aseismic structural system by installing hysteretic devices.

• A study on seismic design syntheses by considering ductility responses of stiffness and strength asymmetric frame structures

  In this paper, inelastic seismic behaviors of "stiffness and strength" asymmetric frame structures are investigated. The effectiveness and importance of "high ductility" design for asymmetric structures are emphasized to reduce dispersion of structural response caused by eccentricity. Comparative studies by using various kinds of asymmetric frame models which make different values of "maximum ductility factor response" are executed through numerical simulations. Analytical procedures are operated by extraction of each hysteretic model according to each value of maximum ductility factor response which is targeted on the frame model. Various cases of maximum ductility factor response are evaluated. As a result, it is assured that high performance of energy absorption is operated by introducing high ductility efficiency to asymmetric frame model.

• Active air-bag control system for building vibrations induced by seismic excitations

  Koji Yasui, Yoichi Mukai, Kiyoji Izawa, Tadamichi Yamashita, Eizaburo Tachabana, Yuaka Inoue

  To improve structural safety under seismic excitations, a new type of active response control system which is named an 'active air-bag control system' is proposed. The argument of this paper is put on the upgrade of the system efficiency from the pilot model of the active air-bag. At first, the following two improvements are carried out as the hardware progress: 1) installing friction-less type of air-cylinders, 2) replacement of air pressure regulators into high-speed response type. By those progress, high performance of the control system is actualized. To accomplish effective aseismic response control by making the most of those progress, modification of the control algorithm is investigated. Emphases are put on the response prediction methods and the index functions. Active control tests are executed for the experimental model of the active air-bag system on the shaking table. As a result, the suitable condition of the control algorithm to actualize effectiveness of the active air-bag are assured.

• Seismic response of asymmetric frame structures introduced inter-story hysteretic dampers

  Tadamichi Yamashita, Yoichi Mukai, Tadatoshi Furukawa, Masami Hanai

  To reduce structural responses caused by earthquake excitations, various kinds of damper systems are introduced to building structures. However, most of structural design for installing damper systems have been investigated only for symmetric frame structures. To avoid large displacements at the flexible-edge caused by torsional responses, reductions of eccentricity are aimed on general design of asymmetric structures. The concepts of those structural design are based on syntheses to make dynamic behaviors of building structures as to be within elastic region, so inelastic behaviors of stiffness and strength asymmetric frame structures have not been considered sufficiently. In this paper, an emphasis is put on investigations for effectiveness of hysteretic dampers introduced to stiffness and strength asymmetric frame structures. To investigate inelastic behaviors of hysteretic dampers installed to asymmetric frame structures, numerical simulations are executed. As a result, it is assured that, by adequatly locating hysteretic dampers to the asymmetric frame structures, inelastic structural responses regarding to the maximum displacements can be reduced to the same level with that of symmetric frame structures.

• Active air-bag control system for building structures (Development of experimental apparatus and preliminary experimental tests)

  Kiyoji Izawa, Koji Yasui, Yoichi Mukai, Eizaburo Tachabana

  A new type of active control system named an 'active air-bag control system' is proposed for reducing responses of building structures under various kinds of external disturbances. And also, the active air-bag system aims to control maximum inter-story displacements of building structures for shock motions. Main concept of the active air-bag system for building structures is introduced from the idea of human safety system of automobiles. In order to investigate control effects of this system, an experimental apparatus was developed and preliminary experimental tests are executed. Air cylinders which can generate the active control force are adopted as control devices of active air-bag system, and those are located on the lowest story of the structural model. As testing results, remarkable reduction of vibrations can be observed on the response control of free vibrations and also for harmonic excitations.

In this paper, emphasis is put on optimal arrangements of active control force of each control device. To control the multi-located active braces system, a 'digital-optimizing control method' is installed as a control algorithm. On the point that the aseismic active control algorithm should be simple and effective, the digital-optimizing control method is fairly advantageous and applicable for practical use of active control system. Through numerical simulations, optimal arrangements of control force of each control device of active brace are examined, and also the effectiveness of this control algorithm is examined. As a result, it appeared that the control forces of lowest story is very important for response control by multi-located active braces, and more effective reductions of response can be gained by introducing optimal arrangements of the control forces of higher stories.

• Digital-optimizing control method on active structural response control system for earthquake excitations

  Takuma Kuroda, Yoichi Mukai, Eizaburo Tachabana, Yutaka Inoue

  A 'digital-optimizing control method' is proposed as a new practical method for active control systems of building structures. To investigate this control method, a 'multi-located active control system' using active braces is adopted. In this paper, an emphasis is put on the active structural response control for earthquake excitations. On the point that the aseismic active control algorithm should be simple and effective, the digital- optimizing control method is fairly advantageous and applicable for practical use of active control system. To control multi-devices efficiently, a 'digital index function' is introduced onto the optimization of control performance. Through numerical simulations, the effectiveness of this algorithm is examined. As a result, it appeared that remarkable control effects are obtained by introducing the digital-optimizing control method into multi-located active control system.

  Mizushima Yasunori, Mukai Yoichi, Ohno Masahito, Saruwatari Tomoharu

  It is intended to prevent buildings from collapsing under earthquakes which are expected previously. In other words, it is not cleared and considered how buildings behave under sever unexpected earthquakes. However, to reduce damage caused by unexpected earthquakes, it is very important to clarify behaviors of buildings under such earthquakes and expose the potential risks. In this report, buildings are modeled to reproduce their shape as precise as possible by FEM. So the model can be express from local damage to buildings’ collapse. Using this model, collapse analysis was executed and expose potential risks in building collapse .

  Buildings are required to protect human lives, reduce damage and keep functions according to the use of the building. The occurrence of the long period ground motions and pulse ground motions is predicted. The important buildings have to keep function, even if those are excited by such ground motions. In this study, researches on the semi-active control of base-isolation system and the active control by large mass damper were conducted for the purpose mentioned above. In those researches, a new verification method of the real-time hybrid simulation using shaking-table and hydraulic actuator (we call this "Dual real-time hybrid simulation") was proposed and response compensation was developed. In conclusions, a semi-active control method for non-linear base-isolation system to reduce the floor acceleration unaffected by hardening of isolators and an active control method to reduce the response displacement were proposed.

  structural construction technology with foldable and deployable mechanisms. Firstly, an improved-type hinge mechanism model is proposed for civil engineering structures. This model is designed to avoid a conflict between panels during motions to change its configurations. Foldable and deployable performance and an out-of-plane action of panels are evaluated through numerical simulations. Secondly, a novel folding mechanism that has slanting folding-line by cutting a panel-edge is proposed for aerospace structures. Visualization of expansion of folded structures and mechanism analyses to expand in outer space are conducted. Thirdly, a 4D-printing method, which is developed as a novel printing process using carbon fiber reinforced plastic (CFRP), is introduced to a joint between the rigid panel and flexible hinge. Deformability and durability of the flexible hinge are examined during deploying motions.

  In this research, we’ve proposed the new structural system that supplies buildings with high seismic performance and robustness, and proved its validity through a series of experimental and numerical studies. The developed system integrates passive energy dissipating devices with mechanical linkages to prevent buildings from collapsing in a few stories. Since this system can be installed to a building from its outside, it is useful to enhance the seismic performance of not only new buildings but also existing buildings.

  For quantitative evaluation for human damage reduction based on two-way verification of "structure simulator" and "evacuation simulator", integrated simulation incorporating "damage simulator" of non-structural materials that has been addressed in this research Created a visualization tool to implement. The validity of the "damage assessment observer" function and the "damage control operator" function was verified based on the result of integrated simulation. Evacuation hazard verification by "Evacuation Simulator" was continuously conducted with damage evaluation from "Injury Simulator" linked with this based on the analysis result of the structural simulator as initial condition. As a result, the "damage control operator" function identified the key element.

  The aim of the research is to clarify development process of urban blocks and their townhouses from the field survey in the old city of Bhaktapur in Nepal registered as World Cultural Heritage. The areal extent of distribution of townhouses as units forming an urban block is judged by the votary area of Hindu gods and occupational surnames. Based on measurement survey of townhouses within this extent, historic development of the urban block is analyzed with regard to the historic difference of townhouses’ floor planning. This also leads to the findings that townhouses have different facades between opposite sides of a street/lane. The historic urban landscape of Nepali cities is formed in such a way that closely relates with the development process of urban blocks.

  We focus the buildings and their elements’ behaviors due to impacting-objects; for example, non-structural elements' damages as causing serious human injury or a progressive collapse over the entire buildings. However, hazardous actions of the buildings or their elements accompanying to the general impulsive accidents have not been evaluated enough quantitatively. Thus emphasis is put on making collapse behaviors of various building elements quantify through data extraction with the video motion capturing. Destructive tests using glazing specimen are executed and the impacting moment of the plate glass versus the flying object are recorded with the high-speed video camera. Scattering motions of broken glass pieces are observed quantitatively with motion extracting analyses. FEM analyses are also carried out. By comparing the simulation and the experimental results, it is assured that the FEM analysis can well-reproduce actual behavior of the breaking glass due to flying object.

  A damper developed by authors uses both the mass effect by rotary inertia and the variable damping effect by magnetorheological fluid. The negative spring property by inertia mass and significant energy absorption by MR fluid are confirmed. Authors intend to carry out practical realization of rotary inertia mass damper using MR fluid. In this research, through the real-time-hybrid experiment with the use of "MR rotary inertia damper", the seismic response properties are discussed by changes in the parameters on building structure. From the knowledge obtained by the experiment, the authors propose the semi-active control method focused on input velocity of earthquake. Then, in comparison with passive control, it have been confirmed the effects of the displacement reduction in the all case of experiments performed in this research. Especially, in the case of near-fault earthquake ground motion, it have been confirmed both floor response acceleration and displacement were reduced.

  The object of this research is to investigate the collapse mechanism of pilotis buildings, and to develop a new structural system for preventing the collapse at the first story of buildings. In order to investigate the collapse of reinforced concrete pilotis building, a numerical integration method was developed using the correct instantaneous stiffness of elements by predicting the time increment compatible with stiffness variation. The collapse of reinforced concrete columns was discussed using fiber model at plastic hinge and considering the horizontal and vertical vibrations. It was found that column models will collapse at a smaller earthquake input level for a simultaneous input of vertical motion, the ultimate safety of buildings should be evaluated considering the 3-dimensional dynamic behaviors of vertical members. Recent near-fault earthquakes shown strong pulse-like ground motion component in velocity, explicit formulas and simplified methods are efficient to highlight the destructive power of ground motions. Here, earthquake motions are simplified as rectangular acceleration pulses and velocity pulses that are solely related with peak values of ground motions, and explicit formulas are obtained that give an extremely simple correlation between structural response and seismic demand with peak values of ground motion. In order to eliminate deformation concentration of building structures, Rocking Center Designated (RCD) Mechanism is proposed to control the vibration modes. Firstly, the dynamic characteristics of this new structure were investigated, and its seismic design method was proposed. The effectiveness and advantages were discussed for design of new buildings and for retrofitting of existing buildings. To confirm the vibration properties of this new structure, Small shaking table tests were carried out to confirm the function of RCD mechanism for displacement distribution. Test results shown that the vibration mode of the main structure varies according to the rocking center of RCD mechanism. If the rocking center is under the ground level, then the first vibration mode will be predominant, and will be solely decided by the rocking radius geometrically, and the story forces are effectively relocated by RCD mechanism. This new structure system is expected to meet different performance needs for distributing the first mode displacement, and to choose the most suitable structural member for strength, deformation and energy consumption.

  本研究計画では、アクティブパワードマスカプラ(連結振り子)式制震(振)システムの開発を目指し、最終年度は、本制震システムの特性を生かした具体的な応用手法を提案するための研究に取組んだ。アクティブパワードマスカプラは、構造物に設置した動吸振器の付加質量部を、地盤面等の固定面とも別途連結し、アクチュエータでこの連結材のふるまいが、みかけ上負剛性を有するように制御を行うシステムであり、動吸振器に要求される付加質量を大幅に低減しても、同等の減衰性能を維持可能なような改良が加えられる。前年度の研究では、実験装置の試作によりアクティブパワードマスカプラの性能評価を行ったが、模型レベルでは制御装置の減衰調整がフレキシブルに行えないため、実験条件は限定されていたが、免震構造のような長周期の振動系の特性改善のための本システムを利用の有望性が指摘された。 そこで本年の研究では、この成果を裏付けるため、免震構造物系を対象とし、その特性改善にアクティブパワードマスカプラを利用するための設計法の提案を目指し、数値実験を中心とした検証を行った。得られた成果を概述すると以下のようになる。 (1)免震構造物系に設置される粘性減衰要素は、免震化領域の周波数成分をもつ外乱入力に対し、免震効果を損なうが、アクティブパワードマスカプラを代置することで、その特性は改善可能であることが示された。 (2)定点理論に基づき誘導したパワードマスカプラ式制震システムの調整式を連結振り子付きハイブリッド式免震構造物に適用するための設計法を提案し、数値実験により地震時挙動のシミュレーションを行った結果、提案手法の有効性が示された。 (3)パワードマスカプラ式制震装置を免震構造物の支承部に設置することにより、長周期成分を含む外乱に対しても、免震層の加速度応答増加が抑制されると同時に、免震層の変形抑制効果もあるが示された。
