摘要: 对一个10层方钢管混凝土框架结构进行了push-over分析,为方钢管混凝土框架结构的抗震性能分析提供了参考数据。在此基础上与钢筋混凝土框架结构的push-over分析结果进行了对比研究,从理论上比较了两种结构的动力特性。

Abstract: The seismic behaviors of four kinds of 10-story frame structures, which are respectively composed of concrete-filled rectangular steel tubes (CFRT) and of reinforced concrete columns, have been studied. SAP 2000 program is used for calculating the seismic responses of the structures. Dynamic behaviors of the CFRT and reinforced concrete structures are analyzed, which may be referenced for structure design.
