摘要
对非线性串联体系进行了随机地震反应分析,地震动随机过程模型采用常用的非平稳过滤白噪声模型,非线性主要考虑其材料的非线性,滞变恢复力模型采用Bouc-Wen模型,获得了结构地震随机反应的反应样本,利用Monte Carlo模拟方法,统计分析了结构在不同限值水平下的失效概率,分析了串联体系与其单元失效概率的关系。
Random seismic reliability for nonlinear tandem system is analyzed in this paper. The non-stationary filtered white noise model is used to simulate the random process of the seismic ground motion. Bouc-Wen model is chosen to describe the material nonlinear character. Using the computer cal- culation procedure, plenty of stochastic seismic response samples are obtained. Failure probability of dif- ferent limit levels are counted by Monte Carlo simulation and then the relationship of failure probability between the tandem system and its element are analyzed at last.
