    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.

■ Research Themes
  • 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

    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.
