摘　　要：为研究型钢-混凝土混合结构的抗震性能,应用OpenSEES有限元软件,建立了一个型钢-混凝土柱拟静力加载分析数值模型。利用结构有限元分析软件ETABS建立了一栋6层型钢-混凝土柱框架结构的地震动力反应数值分析模型。计算结果表明型钢混凝土柱构件具有较高的屈服点、较好的延性;滞回曲线饱满,具有较高的耗能能力,刚度退化过程平稳。型钢混凝土柱框架结构具有较好水平承载力和抗震性能,实现抗震目标。Applying finite element software OpenSEES,a quasi-static loading numerical model for steel reinforced concrete column is eslablished,to study its seismic performance.Then,with structural element software ETABS,an analysis model for a 6-floor frame structure with steel reinforced concrete composite columns is present.The results show that this type of column exhibits high yielding point,favorite ductility,plumb hysteresis loop-satisfied energy dissipation capacity and stable stiffness degrading,in horizontal direction.For the overall structure with this type of column,it also exhibits good load bearing capacity and good seismic performance.
