基于增量动力分析的钢框架结构抗震性能评估
Seismic performance evaluation of steel moment-resisting frames using incremental dynamic analysis
摘要
Abstract
Taking a 3-storeyed steel moment-resisting frame, a 9-storeyed one and a 20-storeyed one respectively as an example, an incremental dynamic analysis （IDA） was performed on the three mod- els under near-fault ground motions to do seismic performance evaluation with different intensitymeasures to predict the seismic capacity of structures. Based on IDA, through the perspective of prob- ability, seismic hazard curves, mean annual exceeding probabilities and return periods were gotten un- der different intensity measures. Through comparative analysis, it shows that, for models with differ- ent storeys, the effectiveness of the choosing of intensity measures to do seismic performance evalua-tion is different. These three structural models are all suitable for using S~ as intensity measures. For 3-storey steel frame, it is not suitable for using aPGA as intensity measure. For 9-storey steel frame, it is comparatively suitable for using aPGA as intensity measure. However, for 20-storey steel frame, the effectiveness of using aPGA as intensity measure needs further investigations.关键词
