- Structural redundancy assessment of steel aqueduct bridges is made by the analysis of a case study using the Musota Aqueduct bridge structure: a simply supported steel arch bridge erected in 1973 and a seven- span continuous steel aqueduct bridge. In this paper, as a case study, after the validation of the model, the structural redundancy of the Musota aqueduct bridge in Wakayama City with respect to its load-carrying capacity after the failure of hanging components due to corrosion was investigated. The conventional procedure for the assessment of redundancy makes use of static nonlinear structural analysis. A three-dimensional finite-element model of this bridge was developed to simulate its behavior. The results from the linear analysis are compared with those from the nonlinear analysis to investigate the appropriateness of the former in the evaluation of redundancy. A detailed nonlinear static finite element study is carried out into the hangers' components of the arch bridge in order to clarify the implications involved in the failure of redundancy. Finally, recommendations for prudent bridge maintenance methods are presented based on findings from the investigation.Last, International Journal of Innovative Science and Research Technology, Oct. 2024, International Journal of Innovative Science and Research Technology (IJISRT), 9(10) (10), 1189 - 1198, English[Refereed]Scientific journal
- Pipelines play a vital role in ensuring the efficient and secure transportation of water, making their performance to keep the water continuously going vital. This research explores the influence of air valves on the localized damage and overall functionality of the pipelines. Air valves are critical components that help stabilize pressure and prevent vacuum formation. However, their installation can introduce structural weaknesses in localized areas. The study employs FEM modeling alongside field data from a collapsed bridge to assess the performance and damage in the vicinity of air valves. The findings reveal that strategic redesigns, such as optimizing air valve placement and reinforcing surrounding areas, can significantly enhance performance while mitigating local damage. Additionally, the research highlights the effectiveness of repair methods in increasing pipeline resistance to bending stresses and compares various repair and design approaches, providing new insights into mitigating structural damage in aqueduct bridges. This study addresses a critical gap in the literature, offering a thorough approach to understanding and addressing air valve-related damage in engineering.Last, International Journal of Innovative Science and Research Technology, Oct. 2024, International Journal of Innovative Science and Research Technology (IJISRT), 9(9) (9), 2344 - 2349, English[Refereed]Scientific journal

Referring from the case where several pipes with large diameter had damaged with cracks by the earthquake in northern Osaka in 2018, it is considered that not only factors such as insufficient strength and deterioration but also that the pipes with larger diameters is more vulnerable than those with small diameters for the seismic resistance in the transverse direction, which is a so-called size effect. In this study, the more accurate calculation method using soil-and-pipe FEM model and giving inertial force without using soil spring. The influence of the diameter on the seismic response for water pipes with small to large diameters are made clarified. Furthermore, the seismic resistance was compared under various conditions with regard to the damage factor of the 900 mm diameter pipe during the last earthquake. As a result, it was found that the reduction in pipe thickness due to corrosion deterioration contributes more as a damage factor than the increase in hydraulic pressure during the earthquake.

In the guideline for seismic design of buried pipes, the characteristics of the ground spring in the pipe axial direction, which represents the dynamic interaction between the pipeline and ground, are important for evaluating the seismic resistance of the buried pipes under the seismic forces. The ground spring characteristic in the pipe axial direction is modeled as a bilinear type in which the slip occurs between the pipe and ground if the shear stress exceeds a certain limit. However, the buried pipe has joints, and the friction in the pipe axial direction includes the friction due to the joint's overhanging part, but their modeling has not been sufficiently studied. In this study, in order to understand the movement of soil particles around the joint when shear displacement is applied, an shear deformation experiment that the pipe and the soil particles are replaced by a two-dimensional cross section was carried out. The movement of soil particles was visualized and the friction mechanism was clarified microscopically.

Seismic resistance of water supply facility and pipeline is promoted to reduce suspension of water supply by an earthquake. Lightweight welded steel pipes with seismic resistance have been widely used for pipeline attached on the bridge. However, there are problems on securing engineers for the field welding method and maintenance. A connection method with seismic resistance, no risk of water leak and easily connection is expected. This study aims to develop mechanical fittings of steel pipe confirmed with seismic resistance equal to or higher than that of welding joints. It can connect easily and reliably by non-specialist engineers. Design verification and verification test were carried out. The seismic resistance of mechanical fittings of steel pipe equal to or higher than that of welding joints was confirmed.

As a method for evaluating the seismic performance of buried pipelines for fluid transportation such as water supply, industrial water, and agricultural water, response displacement method is applied. In the case of seamless continuous pipelines (integral structure pipelines) such as steel pipes and polyethylene pipes, the ground strain acting in the axial direction of the pipe is compared with the allowable strain of the pipe. The critical performance of the polyethylene pipe was evaluated by cyclic tensile and compression load test. As a result, it was revealed that the vibration safety margin is about 25 to 50 times of the equivalent repetition frequency calculated from the earthquakes observed in the past. In addition, since the PE pipe has a small elastic modulus compared to steel pipe, it is feared that it will be damaged during construction or other works in service. The seismic performance in the case with scratches on pipe was also evaluated. It was also confirmed that the seismic performance did not deteriorate within the allowable range for scratches set based on the long terms water tightness.

- Axial soil spring between the pipe and ground is treated under the assumption that only a static friction acts. A simple coulomb friction is used in many of seismic response analysis on the buried pipe. In this study, the velocity dependency of shear stress between the pipe and ground was tried to make clear by the real-scale pipe pulling-out test using the shaking table. As a result, it has been understood that the maximum shear stress are different about twice depending on the pipe-moving velocity, and the maximum shear stress and the sliding characteristics are different by the ground compacting condition.Japan Society of Civil Engineers, Nov. 2018, 土木学会論文集A1, 74(4) (4), I_568 - I_577, Japanese[Refereed]Scientific journal

- During a northern Noto peninsula scenario earthquake, not only strong motion but also huge tsunami is attacked in Hegura Island, Wajima City, Japan. In this study, first, seismic waveforms in Hegura Island were estimated based on the asperity models with consideration of ground shaking characteristics by microtremor measurements. Next, walking times from the sites of interest to designated refuge place were measured based on in-situ investigation. Finally, using the non-evacuation time during the earthquake and the required evacuation time after the earthquake, we evaluated the difficult area for tsunami evacuation in Hegura Island taking into account the tsunami travel time.Japan Society of Civil Engineers, Sep. 2017, 土木学会論文集A1, 73(4) (4), 796 - 804, Japanese[Refereed]Scientific journal

- During a large scale scenario earthquake, huge tsunami with early travel time is striked in Tobishima, Sakata City, Japan. In this study, ground shaking characterisrtics in the tsunami attack area were evaluated using microtremor measurement with high density. The strong motions in Tobishima were then estimated based on the asperity models considering the ground shaking characteristics. Furthermore, the difficult time for tsunami evacuation during the earthquake was calculated using instantaneous instrumental seismic intensity. Finally, we discussed the influence of the strong motion on the tsunami evacuation based on the relationship between the travel time and the difficult time.Japan Society of Civil Engineers, Aug. 2017, 土木学会論文集B3, 73(2) (2), 222 - 227, Japanese[Refereed]Scientific journal

In this paper, seismic waveforms in the tsunami attack area were first predicted with very high density based on the SMGA models and microtremor measurements. Walking times from the prediction sites to the designated refuge places were then measured. Using non-evacuation time based on the time history of instrumental seismic intensity and measured time based on results of the walking experiment, finally, we evaluated the difficult area for tsunami evacuation in central Ishigaki City.Japan Society of Civil Engineers, Aug. 2017, 土木学会論文集B3, 73(2) (2), 216 - 221, Japanese[Refereed]Scientific journal
- Conventional damage prediction methods for lifeline structures are primarily based on peak ground motion measurements. However, line structures such as lifelines suffer damage that is mainly induced by the strain of the ground and therefore are likely to be vulnerable to sharp spatial changes in the ground motion. In this study, we propose a measure for evaluating the damage incurred by underground water supply pipelines based on the spatial gradient of the peak ground velocity (PGV), in an attempt to quantify the effects of the geospatial variabilities in the ground motion on pipeline damage. We investigated the spatial distribution of the damage caused to water pipelines during the Niigata-ken Chuetsu earthquake on October 10, 2004 (Japan Meteorological Agency magnitude (M-JMA) of 6.8) and the Kobe earthquake on January 17, 1995 (M(JMA)7.3) and compared the surveyed damage with the PGV distribution as well as with the gradients of the PGV calculated around the damage areas. For the Kobe earthquake, we used the PGV distribution obtained by the strong-motion simulation performed by Matsushima and Kawase . In case of the Chuetsu earthquake, we estimated the ground motion using a broadband-frequency-based strong-ground-motion simulation method based on a multiasperity source model. In both cases, we calculated the gradients of the PGV along the geographical coordinates, with the amplitude of the PGV gradient vector being employed as the damage estimator. Our results show that the distribution of damage to underground water supply pipelines exhibits a greater correlation with the gradients of the PGV than with the PGV itself. Thus, the gradient of the PGV is a useful index for preparing initial-screening hazard maps of underground facilities.

- During the 1993 Southwest Hokkaido Earthquake, not only strong motion but also huge tsunami is attacked in Aonae District, Okushiri Island, Japan. Seismic waveforms in the tsunami strike area were already estimated based on the SMGA models considering local site effects. In this paper, walking times from the sites of interest to original refuge places were measured. Using non-evacuation time during the 1993 main shock and evacuation time after the 1993 main shock, we evaluated the difficult area for tsunami evacuation in Aonae District taking into account tsunami travel time. The evaluated difficult area agree well with the actual area of human casualty observed after the 1993 main shock.Japan Society of Civil Engineers, Aug. 2016, 土木学会論文集B3, 72(2) (2), 509 - 514, Japanese[Refereed]Scientific journal
- During a scenario earthquake with MW9.0 along the Nankai Trough, not only strong motion but also huge tsunami is predicted in Shizuoka Prefecture, Japan. In this study, first, seismic waveforms at station sites for ground motion observation in the coastal area were estimated based on the SMGA models considering local site effects. Using non-evacuation time based on the time history of instrumental seismic intensity, the effect of the estimated strong motion on tsunami evacuation was then discussed. Finally, in order to evaluate evacuation time from the strong motion estimation sites to designated refuge places, walking experiments were carried out. The constructed relationship between the evacuation time and the non-evacuation time will be useful for conventional seashore preservation in Shizuoka Prefecture.Japan Society of Civil Engineers, Aug. 2016, 土木学会論文集B3, 72(2) (2), 1 - 6, Japanese[Refereed]Scientific journal

- Iwaki City, Fukushima Prefecture faced water outage two times due to the Tohoku earthquake that occurred on March 11, 2011 as well as due to its following earthquake that occurred on April 11, 2011. It is rare that the big earthquakes with different mechanism occur in a short term of one month. In this study, the pipeline damage of Iwaki City due to these earthquakes were focused on and it was tried to clarify seismic vulnerability of pipe attribute based on the earthquake damage analysis on water-supply pipeline. As the result of analysis on the seismic vulnerability factors of pipe material, pipe diameter and its micro-topography, the seismic vulnerabilities on pipe diameter and material were very similar between two earthquakes. The seismic vulnerability on pipe diameter was also similar to that in earthquakes in the past, while the vinyl chloride pipe was evaluated to be stronger. The micro-topography factor does not always need to add seismic vulnerability depending on the evaluation of seismic motion.JAPAN ASSOCIATION FOR EARTHQUAKE ENGINEERING, Jul. 2016, 日本地震工学会論文集, 16(8) (8), 145 - 155, Japanese[Refereed]Scientific journal

- During a scenario earthquake with MW 9.0 along the Nankai Trough, not only strong motion but also huge tsunami is predicted in Suruga Bay area, Shizuoka Prefecture, Japan. Reliable estimation of difficult time during the earthquake in the areas is required to clarify tsunami evacuation. In this study, accuracy of the method to estimate difficult time for tsunami evacuation was investigated quantitatively at permanent station sites for strong motion observation with very high density in the focal area. The results indicates that the methods based on temporary earthquake observation or microtremor measurement in tsunami attack area lead to reliable estimation of difficult times for evacuation.Japan Society of Civil Engineers, Mar. 2016, 構造工学論文集A, 62A, 259 - 272, JapaneseScientific journal

- Local government and other private companies have installed motion networks consisting of a large number of seismometers since the 1995 Kobe earthquake, for the purpose of obtaining information on seismic motion in real time and predicting damage immediately after the earthquake. By the way, some of the damage estimation system adapts instrumental seismic intensity calculated from the observed motion. The observation station at which the motion predominant in short-period is frequently observed causes high seismic intensity in the calculation and overestimation of damage. This study focuses on the observation stations in Hyogo Prefecture and attempts selecting the observation station which frequently records high acceleration in the short-period using earthquake records of recent small or moderate earthquakes and comparing differences between the observed value and the value estimated from attenuation relation.Japan Society of Civil Engineers, Apr. 2015, 土木学会論文集A1, 71(4) (4), 308 - 316, Japanese[Refereed]Scientific journal
- During a scenario earthquake with MW9.0 along the Nankai Trough, not only strong motion but also huge tsunami is predicted in Kushimoto Town, Wakayama Prefecture, Japan. In this study, first, based on the empirical relationship between microtremor H/V spectrum and site amplification factor, the site amplification factors from seismic bedrock to ground surface at the 525 sites in the tsunami attack area were evaluated. Seismic waveforms in the area were then predicted with very high density based on the SMGA models considering the empirical site amplification factors. Using the detailed distribution of several indices due to the predicted seismic waveforms, finally, we discussed the influence which the action of the strong motion has on tsunami evacuation.Japan Society of Civil Engineers, Apr. 2015, 土木学会論文集A1, 71(4) (4), 123 - 135, Japanese[Refereed]Scientific journal

- Occurrence of liquefaction in the wide range of Kanto plain has been reported after the great Tohoku earthquake. Tremendous damage associated with the liquefaction includes damage on residential houses, roads, and water and sewage systems. As professional engineers and researchers who design and construct water treatment and sewage plants and pipelines, and study geotechnical site conditions, the authors conducted investigation through interviewing with the responsible personnels in Chiba Prefecture, Urayasu city, Itako city, Wanigawa water treatment plant, and Amagasaki city which suffered severe damage at the 1995 Hyogoken-Nanbu earthquake. Based on the hearing investigation, analyses are made on characteristics of those damages due to liquefaction and local site conditions and some measures for mitigation are introduced.Japan Society of Civil Engineers, Apr. 2015, 土木学会論文集A1, 71(4) (4), 983 - 994, Japanese[Refereed]Scientific journal
- The 2011 Tohoku, Japan earthquake caused extensive liquefaction to the coastal area of the Tokyo Bay and to the lower banks of the Tone River in North Kanto region. Since underground water pipeline is pulled out at the joint part due to the liquefied ground deformation, the number of pipeline damage would be an indicator of the liquefaction severity. Referring to the analysis of pipeline analysis in the Kashima region along the lower banks of the Tone River, the pipeline damage was not homogeneously distributed but concentrated locally in the size of 1 km2. This study analyzes this concentration area from the landform and land use change. The damage concentration area was able to be clarified by using the old topographical maps compiled in 1880's though it was difficult to specify it by present topographical maps.JAPAN ASSOCIATION FOR EARTHQUAKE ENGINEERING, Dec. 2014, Journal of Japan Association of Earthquake Engineering, 14(6) (6), 21 - 35, English[Refereed]Scientific journal

- The 2011 off the Pacific coast of Tohoku earthquake brought severe damage caused not only by the tsunami but also by the ground motions. The present manuscript summarizes the source mechanism/process and the characteristics of ground motions around eastern Japan during the earthquake. For the last two years after the earthquake, many researchers have devoted their efforts to analyzing and discussing the source and ground motions. New findings from some recent works are also cited. We, furthermore, introduce characteristics of ground motions at some typical damaged sites, where no records of ground motions were obtained during the main shock, using time histories of after shocks.Japan Society for Civil Engineers, Nov. 2013, Journal of Japan Society for Civil Engineers, 1(1) (1), 329 - 342, English[Refereed][Invited]Scientific journal
- When the 2011 off the Pacific Coast of Tohoku Earthquake occurred, an associated tsunami struck the coastal area and a number of river structures were damaged. Two spans out of three of the Yanoura water-pipe bridge (Kamaishi city, Iwate Prefecture) were washed away by the tsunami. For prevention of important infrastructures such as water-pipe bridges, it is nessesary to reinforce them against tsunami. Therefore, detailed examination of tsunami attack on the Yanoura water-pipe is important. In this study, a vertical two-dimensional numerical simulation was applied to two longitudinal river profiles, focusing on the effect of the distance between the water-pipe and Yanoura road way bridge which is located just downstream of the water-pipe bridge. The results obtained in each case are compared in regard to horizontal forces, vertical forces and torque. According to the comparison, the effect of these forces upon the damage of water-pipe is discussed. As a result, it is suggested that an especially large torque contributed most considerably to the damage causing the water-pipe to be washed away. For verification of the results from 2D analysis, three-dimensional numerical simulation was also conducted. It is concluded that 2D analysis is sufficient to estimate the wave forces in each case.土木学会, Aug. 2013, 土木学会論文集 B3, 69(2) (2), 353 - 358, Japanese[Refereed]Scientific journal

- During the 2011 off the Pacific coast of Tohoku Earthquake, Naka-River Aqueduct, Ibaraki Prefecture, Japan, suffered significant damage including pipe dropout in expansion joints. In this study, to estimate strong ground motions at the damage site with high accuracy, aftershock observations with a dense array were conducted at the site. Based on the observation records, difference of site effects between the landside area and the riverside area was indicated. The estimated seismic waveforms at permanent strong motion stations with the site-effect substitution method are very consistent with the observed ones, indicating the validity of the method. Finally, the method was used to estimate strong ground motions at the damage site.日本地震工学会, Sep. 2012, 日本地震工学会論文集, 12(4) (4), 374 - 393, Japanese[Refereed]Scientific journal

- We have developed updated attenuation relations for peak ground acceleration (PGA), peak ground velocity (PGV), and acceleration response spectra with 5% damping on the basis of the data (78 earthquakes and 351 records) pertaining to strong ground motion in Iran. Moment magnitude, distance, fault mechanism, site class, and zone were the model parameters considered. A term for the saturation of the acceleration amplitude was also used in the model in order to improve the estimations in near-source regions. A nonlinear regression analysis was performed to obtain the coefficients. A comparison between the data set used in the current study for Iran and two next generation attenuation (NGA) models showed good correlation between our model and the Campbell-Bozorgnia NGA model. The model described is applicable for moment magnitudes from 5.0 to 7.3, distances from 15 to 135 km, and site classes with an average shear-wave velocity at a subsurface depth of 30 m (AVS30) of more than 175 m/s.

- 地域防災力に潜在する全国市町村の地域特性Regional charachteristics of municipality, such as natural and societal environments, strongly affect earthquake disaster pattern. Present study focuses on them and attempts to clearfy the latent regional characteristics in earthquake resistance and response capacity indexes. Through the factor analysis, the combination of a few strong effective indexes can identify coherent distribution of municipality with similar regional characteristcs. This result is useful to imagin the disaster pattern with lessons of earthquake-experienced municipality having similar reginal characterictics and to develop the disaster planning and countermesures with diversity of regionality.地域安全学会, Nov. 2011, 地域安全学会論文集, No.15, pp.445-45(15) (15), 445 - 451, Japanese[Refereed]Scientific journal
- This paper attempts to measure the time available to escape during an earthquake. Because human behavior during a quake has been studied in terms of seismic intensity on the Japan Meteorological Agency (JMA) scale, we used instantaneous instrumental seismic intensity, which can evaluate a sequence of seismic ground motion by the seismic intensity. The available escape time was analyzed using records from different earthquake types and quantified by source distance, magnitude, and earthquake type.JAPAN ASSOCIATION FOR EARTHQUAKE ENGINEERING, Nov. 2011, Journal of Japan Association for Earthquake Engineering, Vol.10, No.5, pp.52-65(5) (5), 52 - 65, Japanese[Refereed]Scientific journal
- Development of Conventional Seismic Diagnosis Chart of Firefighting Underground PipelineFirefighting water pipeline requires seismic safety performance and serviceability after an earthquake. However their periodical maintenance is difficult due to underground installation. This study proposes conventional seismic diagnous chart of the underground pipeline in order to check their seismic safety performance easily. The pipeline network is composed of deformed pipes such as bend, Tee, and several types of fitting as well as straight pipes, and their seismic performance depends on the shape of pipeline. This study analyzes the seismic behavior of pipeline network with comparison of the straight pipelines in terms of the displacements of jointed parts quantitatively. Response due to different types of pipe and other factors is considered as modification coefficient in the chat.地域安全学会, Nov. 2010, 地域安全学会論文集, No.13, pp.257-282(13) (13), 275 - 282, Japanese[Refereed]Scientific journal
- The Indian Ocean earthquake and tsunami occurred in December 2004 caused destructive damage to Phang Nga Province, Thailand. We carried out two times of interview surveys about 1 and 3 years after the event to administrative bodies and lifeline companies for getting the information on lifeline damage, restoration and reconstruction situation, and summarized the basic concept of reconstruction plan of tsunami suffered towns considering lifeline restoration. On the other hand, as for the comparison of reconstruction problems, the lifelines recovery is reviewed at Aonae district in Okushiri Island after the 1993 Hokkaido-Nansei-oki earthquake. As the result, the difference of the process of reconstruction of town and lifelines has been revealed and the importance of preparing of the reconstruction plan before the event under the consideration of a long-term city planning is pointed out.WORLD SCIENTIFIC PUBL CO PTE LTD, Jun. 2010, JOURNAL OF EARTHQUAKE AND TSUNAMI, 4(2) (2), 83 - 93, English[Refereed]Scientific journal
- This paper proposes a method to evaluate functionality of a business after a tsunami disaster. This method has several modules such as damage estimation of business base (building, equipments, and lifeline) caused by tsunami hazard, restoration ratio-to-time model for business base, and the functionality of the business introduced by facility restoration and its influence to the business. As a case study, the tsunami impact to industries and its subsequent restoration process were studied based on an interview survey in southern Sri Lanka after the 2004 Indian Ocean earthquake and tsunami, and the survey results were applied to the proposed model. Results of application showed that buildings and equipments were slowly restored when they were extensively damaged or flooded. Further, the business restoration depends more heavily on the business facilities restoration than the lifeline restoration, when the business facilities are flooded with tsunami inundation higher than 1m.WORLD SCIENTIFIC PUBL CO PTE LTD, Jun. 2010, JOURNAL OF EARTHQUAKE AND TSUNAMI, 4(2) (2), 73 - 81, English[Refereed]Scientific journal
- Damage estimation relationships have been proposed based on seismic ground motions and pipeline damage records from past earthquakes as a technique for understanding damage in future seismic hazards. This kind of relationship is formulated by correcting the standard damage relationship shown by the amount of damage from seismic ground motion with coefficients such as pipe materials and ground conditions. However, the existing relationship is based on the actual earthquake data, and has not yet been verified by numerical analysis. In addition, there is little data on pipeline damage by high-level seismic ground motion from the 1995 Kobe earthquake, and we cannot compare those in the other earthquakes. Therefore, this study was conducted to analyse the damage tendency by using the seismic response analysis of a pipeline under high-level ground motion with the aid of the discrete element method (DEM), which can express slipping out and breaking of the pipeline joint. The damage tendency to the pipeline was evaluated relatively by giving the characteristic of the pipe material and joint. © IWA Publishing 2010.2010, Journal of Water Supply: Research and Technology - AQUA, 59(6-7) (6-7), 400 - 407, English[Refereed]Scientific journal

- 地震時工業用水道供給停止による受水企業への波及This paper addresses the effects to industrial companies due to interruption of industrial water supply during the 1995 Kobe earthquake. Needs of industrial water are classified by the types of the business resiliency of companies analyzing the damage of company facilities, lifeline interruption and their response. The amount of water outage and cost due to the business interruption are evaluated by the type of business resiliency. Oil insdusties were serious for industrial water outage. Moreover, the effects by the recovery strategy of the industrial water suppy at the earthquake are also evaluated in terms of the amount of water outage, days of business interruption and cost.地域安全学会, Nov. 2009, 地域安全学会論文集, No.7, pp.267-274.(11) (11), 267 - 274, Japanese[Refereed]Scientific journal
- Water supply is vital for our life after an earthquake. Prompt staff mobilization and allocation of human resources are expected for sustainable water supply. This study purposes a model to evaluate staff mobilization of water supply departments based on the results of questionnaire survey on the staff mobilization of Osaka City Waterworks Bureau during the 1995 Kobe earthquake. In this model, the time from event to office arrival and the potenstial that a staff can come to office are calculated. This model can also evaluate the time delay under transportation disruption. Simulation of staff mobilization can estimate staff availability for emergency waterworks in terms of number and response time.Japan Society of Civil Engineers, Oct. 2009, 土木学会地震工学論文集, 第30巻, pp.536-543(1) (1), 536 - 543, Japanese[Refereed]Scientific journal

- Water supply is vital for our life especially after an earthquake. In the water supply departments in large cities in Japan, more than 1,000 employees commute for 1 hour on average using several means of transportation. If an earthquake or other event occurs in the middle of the night or early in the morning, staff mobilization would be delayed due to the malfunction of public transportation systems and staff personal issues. This study purposes a model to evaluate staff mobilization for water supply departments based on the results of the questionnaire survey in Osaka City during 1995 Kobe earthquake. It also discusses one phenomenon about inter- dependence of water supply and transportation systems. Simulation of staff mobilization can estimate staff availability for emergency waterworks in terms of number and response time. © 2009 ASCE.2009, TCLEE 2009: Lifeline Earthquake Engineering in a Multihazard Environment, 357, 117, English[Refereed]International conference proceedings
- 写真測量による街区建物群の地震被災度調査・診断方法の開発Earthquake damage survey and diagnosis for building shall be done as soon as possible after the occurrence of earthquakes. However, current survey method takes long time. For example a survey team can judge damage about 15 houses a day on average. This study proposes a new survey and diagnosis method by measuring the coordination of several markers of damage building in the area of town block, and evaluating by the tilt angle of the building by the use of digital photogrammetry, which ensures the survey in accurate and prompt ways. The tilt angle of each building in the town blocks can provide effective information for disaster emergency response.地域安全学会, Nov. 2008, 地域安全学会論文集, No.6, pp.297-304(10) (10), 401 - 408, Japanese[Refereed]Scientific journal

- Effective emergency transportation for saving human livesTo save lives immediately after a catastrophic earthquake occurs, it is essential for an urban transportation system to retain its functional performance in order to carry injured people to hospitals. Recent seismic assessment studies have mostly been based on cost-benefit analyses, carried out in monetary terms that are reasonable for long-term considerations. However, many problems of seismic risk management still remain. For example, attributing a monetary value to a human life is considered impossible. Also, requirements for functioning of a transportation system are different in the period immediately after an earthquake. This paper concentrates on how to assess the importance of an urban transportation system as it relates to saving human life, and what system enhancements should be made to improve performance. This paper proposes a risk assessment method for the functional reliability of a transportation system immediately after an earthquake. In that period, system malfunction adversely affects the saving of lives as a result of time delays when moving injured people to medical facilities. A system dynamics simulation of transporting injured people is incorporated in the method, which uses two assessment approaches to evaluate the differences of cumulative injured people who receive medical care. In deciding on the destination of medical facility in the simulation, two ways of deciding are addressed; one uses information only on the road network, and the other uses information on both road network and hospital availability. Results of an application to an actual target area show the most vulnerable road links and differences of the two decision-making processes. A way to mitigate the loss due to damage to road links is examined. The paper also summarizes future developments in advanced information technology for emergency transportation systems.KLUWER ACADEMIC PUBL, Sep. 2004, NATURAL HAZARDS, 33(1) (1), 23 - 46, English[Refereed]Scientific journal

- International Collaboration in Lifeline Earthquake Engineering 2016 - Proceedings of the 7th China-Japan-US Trilateral Symposium on Lifeline Earthquake Engineering, 2016, English, American Society of Civil Engineers (ASCE), In the current seismic design of a buried pipe, the axial ground restraint force between a pipe and the ground is modeled as a bi-linear system with respect to the relative displacement. In other words, the soil friction determining the ground restraint force is assumed as constant regardless of the pipe velocity. However, it is thought that the soil friction depends on pipe velocity because of the relocation of the soil particles. This study attempted to examine the velocity dependency of the dynamic soil friction using a pipe-pulling test on a shaking table. The conclusions were as follows: (1) the maximum friction in the low velocity case was larger than that in the high velocity case, (2) the soil dilatancy affected the friction, and (3) the friction in the cases with a pipe fitting was 1.5 times larger than that without the fitting regardless of the pipe velocity.Experimental Study on Dynamic Soil Friction along a Buried Pipe

As a sammary of the research report, lifeline facilities had no damage due to the groud motion of earthquake, but facilities in the coastal area had severe damage due to tsunami wave. Especially, scouring damage of pipeline due to tsunami wave was remarkable. Buried electric power cable had no damage due to tsunami wave, and would be good tsunami measures to mitigate lifeline damage from tsunami.スマトラ沖地震・津波におけるタイのライフライン被害と復旧

The results were compared with those obtained by the preceding survey in Hokudan town. Risks of occupant entrapment increases according to the damage level and are found consistent in the two surveys. In case of the Higashinada survey, urban characteristics of dwellings seem to have affected to the entrapment conditions and SAR activities.Comparison of Occupant Entrapment in Higashinada Wand and Hokudan Town in the 1995 Hyogo-ken Nanbu Earthquake

For the typical inter-plate earthquakes such as 2011 Off the Pacific Coast of Tohoku earthquake and coming Nankai Trough earthquake we developed pseudo point source model and carried out the simulation of strong ground motion. For the active fault-induced earthquake like the 2016 Kumamoto earthquake, we estimated the resilience and robustness of infrastructure against a large displacement due to fault movement. Moreover seismic behavior and performance under the multi-hazard of strong ground motion, geohazard and tsunami were investigated.

In particular, it has been observed in past research that the friction depends on drag speed, however the mechanism of the dependence has not been clear. We found the similar phenomenon via both the element test by granular materials consisting of acrylic cylinder and actual test by sand box. The mechanism was clarified by numerical analysis (DEM).

In this study, we make clear an aseismic safety level of infrastructure, structural and functional capacity of infrastructures for the social requirement and the countermeasures for preventing earthquake damage. We assessed an adequate input ground motion for the design of structures, and evaluated the earthquake and tsunami prevention strategies and countermeasures especially for lifeline systems such as railway, roadway, water, gas, electricity and various pipelines. In order to realize these issues and extend the applicability, we conducted numerical simulations by using such advanced simulation methods as FEM, DEM and SPH. Centrifuge experiments were also conducted to verify such computer simulation. The results obtained would be useful resources for soft and hard measures of mitigating earthquake and tsunami disasters.

However, the issue to be improved is the absence of perspective that the underground structures with spatially extent should be considered as a line, a plane or a volume structures with 3-dimensional behavior. In this study, we intend to deal with the underground structures comprehensively from their input ground motions to seismic behavior. We conducted the analyses and discussions by considering the suitable aseismic design and countermeasures.

We simulate wave propagation in a liquefied ground introducing the gravity effect. The wave exhibits the similar property with the gravity wave in a fluid medium as decreasing the shear modulus, and sloshing behavior is excited in the medium.

- 日本学術振興会, 科学研究費補助金/若手研究(B), 若手研究(B), 神戸大学, 2006 - 2007, Principal investigator本研究では,中山間地域における水道システムの統合化を背景に,水道事業施設の耐震性や冗長性,復旧機能性に関する評価手法を提案することを目的としている.とくに近年では,甚大な被害をもたらす地震が多発する中,水道事業体においても事業規模を問わず甚大な被害に見舞われている.各事業体では,管路更新および耐震化などの事前対策と,被災後の初動体制や連絡網の強化さらには地震時緊急対応マニュアルの整備などの事後対策の両面から地震防災対策が実施されている.しかし,事前対策を実施するためには,水道事業体の現状把握が必要不可欠となってくる. まず,管路耐震化状況を定量的に評価する手法を提案するとともに事業規模による耐震化低減効果について明らかにした,給水人口規模が小さくなるほど地震に対して脆弱になることが分かった.また,給水人口2万人以上の事業体では,今後10年間の更新方法によって危険度を大幅に低減できることが明らかになった.それ以下の事業体では,管路の耐震化だけでなく,震後の緊急対応の充実化を図るなど事後対策と併せて対策すべきであると考えられる.また,昨年度から分析している中山間地の道路閉塞評価と将来的にリンクさせてシステムとしての評価方法につなげることが課題である. 一方で,事業体の緊急対応マニュアルを収集し,事業規模におけるマニュアル整備状況と緊急対応時の組織状況について分析した.災害時の指令系統を計画している事業体が多かったが,事業規模が小さくなるにつれて職員数が減り,災害担当部署に数名しか配置できなくなることが明らかになった.Competitive research funding
- Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Grant-in-Aid for Scientific Research (A), Kobe University, 2005 - 2006Present paper investigates the existence of active faults and earthquake occurrence risk in Baku City. Also the ground motion intensity and probability of liquefaction occurrence under the estimated earthquakes are researched. The damage of residential houses and water supply trunk lines are predicted under the seismic hazards. (1) Two active faults Fl and F2 are founded in the vicinity of Baku City by Earth Ladder Test. Fl is a hidden fault and F2 is right lateral slip fault. (2) Risk analyses revealed that the earthquake occurrence probability is 70 gal in 100 year return period and 100 gal in 1000 in Baku City. (3) Fl and F2 active faults would cause the maximum acceleration as 200〜400gal in the center area in Baku City, which was analyzed by the fault parameter method. (4) Surface wave test and liquefaction field test show that soft ground are spreading along the coast lines and stiff in the central areas in Baku City. (5) Low rise residential houses would have severe damage under 1000 year return period earthquakes. (6) The method to estimate the damage of water trunk pipelines are established.Competitive research funding
