本研究旨在提出一种评估钢结构建筑在多次强震作用下累积损伤的方法。针对名古屋地区模拟的三种强震，对一个单自由度非线性系统进行了一系列时程分析。通过对分析结果的比较，提出了从单个运动的最大响应值和累积响应值来预测三个运动连续作用的最大响应值和累积响应值的方法。对30个有反应控制系统和无反应控制系统的钢结构高层建筑模型进行了时程反应分析，验证了该方法的有效性。此外，基于《JSCA性能菜单》对这些模型建筑的抗震性能进行了评估。最后，提出了评估建筑物在强震作用下的抗震性能的方法和步骤。
This study is to propose a method to evaluate cumulative damage of steel buildings under plural strong seismic actions. A series of time history analyses on a one degree-of-freedom non-linear system are conducted for three strong ground motions simulated for Nagoya district. Comparing the results of the analyses, a method to predict the maximum and cumulative response values for successive action of the three motions from those of one single motion is proposed. Time history response analyses of thirty (30) storied steel building models with and without response control systems are conducted to verify the proposed method. In addition, seismic performances of these model buildings are evaluated based on “JSCA Performance Menu”. Finally, the method and procedure to evaluate seismic performances of buildings for strong motions that act on the buildings one after one are proposed.
