钢管混凝土结构抗震性能的比较研究

Comparative study on the earthquake behavior of concrete filled steel tubular structures

分别对钢管混凝土柱及钢筋混凝土柱的５层框架结构进行了抗震性能对比试验研究。从理论上分析比较了两种结构的动力特性、多种地震波输入下的结构加速度反应和位移反应，综合评定了钢管混凝土结构的抗震性能，为该类结构的设计提供了参考数据。

In this paper, seismic behaviors of four kinds of 5-story frame structures, which are respectively composed of the concrete filled steel tubular(CFST) and of reinforced concrete col- umn, have been studied. SAP2000 program is used for calculating the seismic responses of the structures. Dynamic behaviors and earthquake responses of the CFST and reinforced concrete structures are analyzed. Comparing the calculation results, the earthquake resistant behavior of the CFST structure has been appraised synthetically, which may be referenced for structure design.
