[摘要]對框架結(jié)構(gòu)的Pushover分析方法進(jìn)行了可靠度分析。該分析過程中的可靠指標(biāo)通過FORTRAN語言編程計算，目標(biāo)位移采用能力譜法（CSM）計算，Pushover曲線通過SAP2000軟件分析輸出。SAP2000的二次開發(fā)技術(shù)使得三者有機(jī)地聯(lián)系起來，實(shí)現(xiàn)了FORTRAN程序?qū)?/span>SAP2000的調(diào)用，使SAP2000的Pushover分析參與到了可靠度迭代計算中。最后，利用一個算例具體闡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.
