[摘要]对框架结构的Pushover分析方法进行了可靠度分析。该分析过程中的可靠指标通过FORTRAN语言编程计算，目标位移采用能力谱法（CSM）计算，Pushover曲线通过SAP2000软件分析输出。SAP2000的二次开发技术使得三者有机地联系起来，实现了FORTRAN程序对SAP2000的调用，使SAP2000的Pushover分析参与到了可靠度迭代计算中。最后，利用一个算例具体阐述了本文提出的方法。

Abstract：Reliability analysis of frame structure based on pushover method is carried out. Reliability analysis is executed through the calculation of FORTRAN programme. Target displacement is calculated by capacity spectrum method. Pushover analysis is output by means of SAP2000 software. The three above are linked by the secondary development of SAP2000 organically. The calling SAP2000 in FORTRAN is thus implemented successfully so as to make pushover analysis based on SAP2000 participate in the iteration calculation. Finally, this method is illustrated through an example.
