OPTIMUM DESIGN FOR SLIDING ISOLATION SYSTEM BASED ON DYNAMIC RELIABILITY ANALYSIS

本文探讨了滑移隔震体系在零均值高斯白噪声地震作用下的优化设计问题,首先利用统计等效线性化方法并按首次超越损坏泊松过程模型的双壁问题得到质点的滑移可靠性函数,然后采用拉格朗日乘子法进行了该滑移隔震体系基于动力可靠性分析的优化设计。

In this paper the problem of optimum design of sliding isolation system under earthquake action modeled as Gaussian white noise process with zero mean is studied. On the basis of obtaining the sliding reliability function of mass point by using the stochastic equivalent linearization method and in accordance with a first-passage failure problem the optimum design of the sliding isolation system is approached by means of Lagrange multiplier method.
