| 摘 要： | 近年来,方钢管混凝土柱-钢梁组合框架结构是在高层建筑中应用较多的一种结构型式.针对汶川地区一个8层方钢管混凝土柱-钢梁组合框架结构,以梁柱线刚度比为计算参数,采用push over分析对该结构地震作用下的性能进行计算分析.研究结果表明,该组合框架结构的梁柱线刚度比不大于0.46时,具有较好的抗震性能,可为其抗震研究提供一些参考数据.

| Abstract: | In recent years,square concrete filled steel tube column-steel composite frame structure is widely used in the high-rise building. In this paper,a eight-storey square concrete-filled steel tube column-steel composite frame structure in the Wenchuan area is studied,with the linear stiffness ratio of the beam and the column as the calculating parameters,using push over analysis on the performance of the structure under seismic action. Research results show that when the composite frame structure of the linear stiffness ratio of the beam and the column is not greater than 0.46,it has a good seismic performance and can provide some references for the aseismic research data. |
