摘　　要：针对按现行规范设计的钢管混凝土框架,应用MonteCarlo随机模拟法,分析结构在小震作用下控制截面失效相关性,由此建立了结构在小震作用下的可靠度分析方法。基于结构总体破坏指标建立的极限状态方程,采用适合强柱弱梁型框架结构分析的杆系模型,提出了钢管混凝土柱框架结构在大震作用下的可靠度分析方法。From the aspects of concrete-filled steel tubular frames designed in accordance with the standard available, a method for Monte Carlo simulation is used to analyze the failure correlation of control profile under the minor earthquake , by which a method for analyzing the reliability of the structure under the “minor earthquake” is established. Based on overall structural failure index, an equation for ultimate status is established. A linkage model of suitable strong-column and weak-beam frame structure is used, by which a method for reliability analysis is presented for CFST under the severe earthquake.
