| 摘 要： | 对基于抗震规范GB 50011和通则CECS 160抗震反应谱的中心支撑钢框架结构的设计地震作用进行了对比,在设计应力比基本一致的前提下,设计了4,10,20层中心支撑钢框架算例并进行了多遇、罕遇地震下的动力响应分析。根据用钢量、层间侧移角、支撑损伤等指标,给出了中心支撑钢框架结构设计地震作用取值的建议。

| Abstract: | In this paper, the seismic force of the steel braced frames calculated by the design spectrum of the GB50011 code is compared to that of the CECS 160,2004 code. With similar design-stress ratios of 4, 10 and 20-storey structure examples are designed and analyzed under frequent and rare earthquakes situntion. At last, according to the index of steel usage, inter-story drift, and brace damage so on. the suggestion about the seismic force value of the braced steel frames is given. |
