摘　　要：本文对地震作用下,采用随机反应谱方法计算滞回结构层问弹塑性最大位移反应中等效参数的确定,提出了改进方法。通过对钢筋混凝土构件和结构模型试验结果的统计分析,给出了钢筋混凝土框架房屋轻微破坏、中等破坏、严重破坏和倒塌状态的变形指标和相应的概率统计参数。In this paper, a modified procedure of selecting equivalent structural parameters is proposed to use the method of stochastic response spectrum for analysis of the maximun elasto-plastic story-drifts of a hysteretic structure. According to the statistical analysis of experimental results of reinforced concrete members and frame models, the deformational indexes and probabilistic statistical parameters of various limit states, such as slight structural damage, moderate structural damage, severe structural damage, and structural collapse in reinforced concrete frame building, are given.
