摘　　要：耐震时程法是一种新型的结构抗震分析方法,其典型特征是随着时间增加地面运动强度不断增大。本文合成3条耐震时程曲线,对一个12层的钢-混混合结构进行水平单向和双向地震作用分析。以10条天然地震动的增量动力分析结果为基准,对耐震时程法的准确性进行验证。研究结果表明,耐震时程法可以很好地预测结构的地震响应。Endurance time method(ETM)is a new type of structural seismic analysis method,and its typical feature is that the intensity of ground motion increases with time.In this paper,three endurance time accelerograms(ETA)were generated,and applied on a 12-story steel-concrete hybrid structures to horizontal unidirectional and bidirectional seismic action to analyze.Based on the results of the incremental dynamic analysis of 10 natural ground motions,the accuracy of endurance time method is tested.Research indicates that ETM predicts structural seismic responses with good accuracy.
