| 摘 要： | 目前对于力学图式为多自由度体系的建筑结构的概率性非线性地震反应分析研究还不多。本文提出了一个实用的方法,对于以剪切变形为主的结构,只要给出结构和地基的有关参数,就能进行非线性的随机反应分析。该实用方法在改进等效线性化方法的基础上,通过引入恢复力的计算曲线处理了恢复力滞回曲线。文中还用该方法计算了两个工程实例,计算结果与Monte-Carlo数值模拟法作了对比,还与一般的等效线性化作了对比。

| Abstract: | This paper presents a practical method for the analysis of nonlinear earthquake stochastic response of structures, which is based on the improved method of equivalent linearization. The hysteretic behavior is taken into account by thecalculating curves of restoring forces. Two numerical examples are given and theresults are also compared with those of Monte-Carlo's and those of unproved me-thod of equivalent linearization method. |
