摘　　要：运用Sap2000有限元软件对钢筋混凝土异形柱框架结构进行Pushover分析。通过主、副惯性矩等效的方法将异形柱简化成矩形柱,建立钢筋混凝土异形柱框架结构,定义塑性铰之后进行静力非线性计算。对分析结果分布的塑性铰、基地剪力-位移、性能点等方面进行定性与定量综合评价,为异形柱在框架结构中基于性能的抗震设计提供参考。Makes a Pushover analysis on the structure of shaped column frame of reinforced concrete by using Sap2000 finite element software. Simplifies the shaped column into rectangular column by methods of lord and vice moment of inertia equivalent, sets up the structure of shaped column frame of reinforced concrete and conducts the static nonlinear calculation after defining plastic hinge. Makes a quantitative and qualitative research on the plastic hinge distribution of the results, the base reaction-displacement and the performance point in order to provide reference for the seismic design of shaped column frame structure.
