【摘要】 本文主要针对地基土-单自由度滞变结构相互作用体系在非平稳高斯随机地震激励下的响应进行了分析。特别是对滞变导致的结构残余变形的发展过程进行了探索。最后结合一个简单数例,将理论计算结果与Monte Carlo法的计算结果进行了比较。比较结果表明,本方法可用来估算结构残余变形的统计量。更多还原

【Abstract】 In this paper, the responses,specially the residual displacement, of a soil - hysteretic SDOF structure interaction system under non - stationary Gaussian earthquake excitaton are investigated. A numerical example of a soil water tower interaction system with non -degenerative restoring force is worked out. Comparing the theoretical results with those calculated by Monte Carlo method,it is shown that the method presented in this paper can estimate the statistic value of the residual displacement with satisfactory accuracy in engineering practice.更多还原
