【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。更多还原

【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.更多还原
