将多级力控制Pushover分析方法与一次可靠度方法(First Order Reliability Method,FORM)相结合,提出了结构整体概率抗震能力分析的FORM有限元可靠度方法。利用OpenSees的有限元可靠度分析模块,将该方法应用于钢筋混凝土框架结构,并与蒙特卡洛模拟法分析结果进行对比。结果表明:该方法具有较高的精度和效率,为结构整体概率抗震能力分析提供了另外一种思路。
Combining the Pushover analysis method with the first order reliability method (FORM), the FEM finite element reliability method for the overall probabilistic seismic capacity analysis of structures is proposed. Using OpenSees finite element reliability analysis module, this method is applied to reinforced concrete frame structure and compared with Monte Carlo simulation results. The results show that this method has higher precision and efficiency, which provides another idea for the overall probabilistic seismic capacity analysis of structures.
