  © 2018 Architectural Institute of Japan. This study reports some results of an investigation on the damage of reinforced concrete slabs subjected to falling objects during construction. Full-scale experiment and finite element analyses were conducted. Falling heights of objects were the experimental parameter. Numerical simulations were validated by the experimental result and the influence of the objects' masses on the damage of the slabs was examined. Experimental and analytical results showed that the falling objects didn't completely perforated the slabs when assumed falling conditions were beyond the perforation limit proposed by Degen. In addition, this formula seemed able to predict the variation in the failure mode.

• Section determination system for steel structures using decremental line search and automatic member grouping

  Soshi Nakamura, Takuya Kinoshita, Eiji Fujii, Naohiro Nakamura, Yasunori Mizushima, Koh Kashima, Shuei Ikeda, Takuya Suzuki, Takaki Tojo

  Despite the recent advances in high-performance computing devices and general-purpose optimization software, optimization technique is rarely used in the practical design of building structures. One of the major reasons is the complicated nature of optimization algorithms that tend to be difficult to understand. This study proposes a section determination system for steel structures using a simple algorithm. The algorithm of the proposed system consists of automatic member grouping and decremental line search based on a full stress design. Further, the validity of this system is verified by comparing the outcomes of the proposed system with the design results of structural designers.

• 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.

• 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

  Yasunori Mizushima, Yoichi Mukai, Hisashi Namba, Kenzo Taga, Tomoharu Saruwatari

  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 is conducted for a steel 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.

• Stiffness and strength of ALC core sandwich slabs adhesively bonded with steel skins

  Hideo Oka, Seishi Yamada, Shinya Igarashi, Yasunori Mizushima

  To reduce the weight of buildings, the lightening of slabs would be very effective way because the slabs are generally the heaviest members in the building skeleton. In this paper, the sandwich panel system has been investigated on account of the reduction ofself-weight as well as the increase of bending rigidity. The present sandwich panels are of an ALC (autoclaved lightweight aerated concrete) core adhesively bonded with steel skins. In order to grasp the fundamental structural behaviors, the four-point bending tests were carried out. The test results have been discussed referring to the analytical results by the simple theory for laminated beams or the previous test results for ALC panels.

• Loaded fire resistance tests and structural properties after heating of alc core sandwich slabs adhesively bonded with steel skins

  Hideo Oka, Seishi Yamada, Yasunori Mizushima, Shinya Igarashi

  In order to reduce the weight of buildings, the lightweight sandwich slab system consisting of an ALC (autoclaved lightweight aerated concrete) core adhesively bonded with steel skins was proposed. In this paper, two hour fire resistance tests under constant dead loading have performed. Subsequently, structural behaviors on the four-point bending tests against these specimens subjected fire heating are studied. Each test results reveal that the steel/ALC sandwich slabs have fireproof qualities with almost the same level as ordinary ALC panel.

  NCTAM papers, National Congress of Theoretical and Applied Mechanics, Japan, Sep. 2014, Japanese, National Committee for IUTAM, Currently, books and real experience such as structural experiments have helped us to understand structural mechanics. Structural analyses (numerical simulations) also have helped. Such simulations have needed complex input interface and specialized knowledge to comprehend the result. Incidentally, high-performance mobile terminal devices are widely spread during recent years. These devices have intuitive interfaces such as touch-screen system. As a result, relationships between computers and users have been changing. In this report, the questionary investigation to students who study structural mechanics has been done in order to search the interface for structural analyses in next generation.


• Study on early striking of slab supports and formworks using genetic algorithm

  Kinoshita Takuya, Mizushima Yasunori, Tamai Katsushi, Taira Shoujirou

  NCTAM papers, National Congress of Theoretical and Applied Mechanics, Japan, Sep. 2014, Japanese, National Committee for IUTAM, In this paper, the rationalization method of a building construction process utilizing optimization algorithm is presented. Forming reinforced concrete slabs, it is necessary to leave many supports until concrete strength is developed enough. The distribution of supports is conventionally determined by simple structural analysis. In this study, we utilize 3-dimensional finite element analysis for these problems and evaluate each response properly. Multi-objective genetic algorithm is applied for the optimization problem to find the distribution pattern so as to minimize the number of supports under the structural constraints.

  NCTAM papers, National Congress of Theoretical and Applied Mechanics, Japan, 2013, Japanese, National Committee for IUTAM, 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 .

• On mechanical behavior of beam-column joint of reinforced concrete buildings subjected by vertical impact load

  Mizushima Yasunori, Tachibana Eizaburo

  NCTAM papers, National Congress of Theoretical and Applied Mechanics, Japan, 2010, Japanese, National Committee for IUTAM, Many reinforced concrete buildings were destroyed at Kobe earthquake (1995). It was observed in several buildings the upper ends of columns in the first floor were broken by compression stress. In this paper, from the point of view of impact load problems, numerical simulations are executed. Impulsive load is given at the bottom of column. It appeared that the vertical stress is decreasing rapidly because of reflection and dispersion via beams. And high level of stress state can be observed at the upper ends of columns. By using some simple assumptions, these facts can be also proved by classic problem of longitudinal impact of rod.

• 統一的基準による鋼構造部材の破断予測手法に関する研究

  水島 靖典, 井上 泰彦

  日本学術振興会, 科学研究費助成事業, 基盤研究(C), 兵庫県立大学, 01 Apr. 2021 - 31 Mar. 2024

  巨大地震時に鋼構造建物に生じる可能性がある「破断」を統一的な方法で予測することは現状不可能である。これは、地震における鋼材の破断を予測するために必要な「形状による応力状態の違い」と「繰返し塑性変形」の両方を考慮したデータ、構成則が存在しないためである。本研究では応力状態の違いと繰返し塑性変形の両方を同時に考慮した破断条件「低・極低サイクル疲労曲面」を構築する。更に、この「低・極低サイクル疲労曲面」に基づいた破断構成則の開発を行う。本研究は、これまで不可能だったあらゆる部材に対して統一的な基準を用いた鋼材の破断予測を目指すものである。 研究初年度である2021年度は応力三軸度をパラメータとするために、試験体に切り欠きを設けた低サイクル疲労試験装置の設計を行った。試験装置は圧縮時の座屈を補剛するための試験体補剛機能と、画像相関法による3次元画像変形計測を行うための試験体の可視性を両立した治具を開発した。開発した実験装置を用いて、ひずみ振幅3%～8%程度の範囲で応力状態を変化させた低サイクル疲労実験を実施した。その結果、応力三軸度が大きいほど同程度のひずみ振幅であっても、亀裂の発生およびピーク荷重の低下が早期に生じることが確認できた。また、実験を行った範囲内では全ての試験体形状において、ひずみ振幅－破断繰返し数をプロットした両対数軸グラフ上でほぼ直線となるManson-Coffin則が成立することを確認した。

  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.
