摘　　要：论文采用有限元软件ANSYS分别建立了三组对比模型。计算分析了钢筋混凝土异形柱和型钢混凝土异形柱框架,具有型钢相同含钢率的型钢混凝土矩形柱和型钢混凝土异形柱框架,具有等形心轴惯性矩的钢筋混凝土矩形柱、钢筋混凝土异形柱和型钢混凝土异形柱框架。研究了对比模型在水平地震作用下的振动反应特性。得出型钢混凝土异形框架柱的扭矩和层间位移都较小;具有等形心轴惯性矩的钢筋混凝土矩形柱、钢筋混凝土异形柱和型钢混凝土异形柱框架三种结构的框架柱扭矩和层间位移非常接近,具有相似的振动反应特性。Three contrastive models were established with finite element program named ANSYS and the special-shaped RC column frame and special-shaped SRC column frame,common SRC column and special-shaped SRC column which had same steel ratio,common RC column,special-shaped RC column and special-shaped SRC column which had same the same inertia moment were analyzed.Their level seismic response performances were studied.Seismic analysis of the former two contrastive models shows that torque of columns and story drift of special-shaped SRC column frame are both smaller which indicates seismic performance of special-shaped SRC column frame is better.Seismic analysis of the latter contrastive models shows that torque of columns and story drift is close which indicates they have close seismic response performances.
