剪切型结构地震破坏准则与抗震可靠度分析

Seismic Damage Criteria and Seismic Reliability Analysis for Shear-Bearing Type Structures

对现有混凝土结构的几种常用地震破坏准则进行了简要的归纳与总结,结合一钢筋混凝土框架结构,在求得配筋结构层间极限变形能力的基础上,利用弹塑性层间位移增大系数法直接统计层间位移的反应结果,采用变形破坏准则的一次二阶矩法对考虑非线性因素的钢筋混凝土框架结构的抗震可靠度问题进行了分析,探讨了这一方法的实施要点。

In this paper, several common seismic damage criteria are summed up and evaluated. Considering nonlinear seismic responses with the elastic-plastic inter-story drift augmentation coefficient method, seismic reliability analysis was performed to a multi-story regular RC frame structure through the mean-variance method and deformation damage criterion. The implementation keynotes of this procedure are also discussed.
