摘要
采用可靠指标β来度量抗震结构可靠度。取结构失效准则为：地震作用下结构层间位移响应超越结构层间位移能力限值。将时程分析方法与Ｊ．Ｃ方法相结合。
The reliability of aseismic structures is measured by using reliability index.The failurecriteria of structures to be used is that the structural story-drift responses under a earthquake should surpassthe structural story-drift capacity .Based on J.C method and wilson -θ method,this paper presents a time-history analysis method for the deformation capacity reliability analysis of aseismic structures.The ramdomof structural parameters is taken into consideration in this method. By using the method,the structrualreliability indexes at any time during an earthquake can be calcutated.
