随机结构地震反应的反应谱分析法

本文将结构弹性模量、构件截面面积、截面惯性矩、质量分布及地震反应谱参数等视为随机变量,建立随机结构动力分析模型,并使用现行抗震规范反应谱进行结构地震反应计算。以此研究上述参数的不确定性(随机性)对结构地震反应计算结果的影响。

Spectrum Analysis Technique of Earthquake Response for Stochastic Structures

In this paper, the elastic modulu, cross-section area and moment of inertia of structual members and the parameters of the seismic respense spectra aretreated as randon variables. A dynamic analysis procedure of a stochastic structure is developed,with which the effect of thece uncertainties on strucfural response is analysed. Finally,an example is given to illustrate the proposed method.
