[摘要] 論文采用有限元軟件ANSYS分別建立了三組對比模型。計算分析了鋼筋混凝土異形柱和型鋼混凝土異形柱框架，具有型鋼相同含鋼率的型鋼混凝土矩形柱和型鋼混凝土異形柱框架，具有等形心軸慣性矩的鋼筋混凝土矩形柱、鋼筋混凝土異形柱和型鋼混凝土異形柱框架。研究了對比模型在水平地震作用下的振動反應特性。得出型鋼混凝土異形框架柱的扭矩和層問位移都較??；具有等形心軸慣性矩的鋼筋混凝土矩形柱、鋼筋混凝土異形柱和型鋼混凝土異形柱框架三種結構的框架柱扭矩和層間位移非常接近，具有相似的振動反應特性。
[關鍵詞] 型鋼混凝土異形柱；抗震性能；扭矩；層問位移

Abstract: 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.
Keywords: special-shaped SRC column; seismic performance; torque; story drift
