摘　　要：耐震时程法(ETM)是一种对增动量分析法(IDA)进行简化的新型结构抗震性能评估方法。为验证此方法在RC框架减震结构中抗震分析的可靠性,文中对RC框架减震结构分别进行ETM分析以及IDA分析,将两种方法得到结构响应情况进行对比分析。研究结果表明,两种分析方法得到的结构响应结果总体吻合情况较好,此方法能很好地预测结构在地震作用下的抗震响应,也说明了耐震时程法应用于RC框架减震结构中的可靠性,且是一种计算效率高的结构抗震分析方法。The Earthquake Time History Method(ETM)is a novel structural seismic performance assessment method that simplifies the Incremental Dynamic Analysis(IDA).To verify the reliability of ETM in the seismic analysis of RC frame damping structures,this study conducts ETM and IDA analyses on RC frame damping structures,comparing the structural response results from both methods.The findings indicate that the structural response results obtained from both analysis methods generally align well,demonstrating that ETM effectively predicts the seismic response of structures under earthquake loading.This confirms the reliability of applying the Earthquake Time History Method to RC frame damping structures and highlights it as a computationally efficient seismic analysis method.
