摘要
本文在总结现有计算土层平稳随机地震反应等价线性化法的基础之上,提出了新的概率平均等价线性化法,以单层土、单自由度水平剪切振动系统为例,用Monte-Carlo数值模拟法对本文方法及其它方法进行了统计检验。结果表明,概率平均法概念明确,精度较其它方法更高,计算也不复杂,是一种较好的方法。
In this paper, the currently used equivalent linear methods for calculating seismic responses of nonlinear soil structures are briefly summarized and some improvements are made. A new approach, the probabilstic average approach, is proposed. A numerical example is presented in detail by using all kinds of equivalent linear methods, including the proposed onet Monte-Carlo simulation method is appeied to examine the results. It is found that the concept of proposed method is more clear and the precision is higher than other approaches.
