| 摘 要： | 针对抗震设防烈度为8度第二组(0.2g)的某异形柱框架结构，运用PKPM软件对结构进行弹性分析，得到首层异形柱的三种类型(L形、T形、十形)节点的梁端及柱端的内力组合值基本参数；再采用有限元分析软件ABAQUS，对各节点在荷载作用下核芯区混凝土受力性能进行分析，得到结构的薄弱环节以及受力破坏特征，为异形柱框架结构在地震作用下的整体工作性能提供理论分析方法。

| Abstract: | For a frame structure of special-shaped columns with seismic fortification intensity for 8 degrees and second group(0.2 g),firstly,flexibility analysis to be done the structure using PKPM software,and got the basic parameter values of internal force combination at nodes of the girder ends and the special-shaped columns with three types of column sections(L shape,T shape,十 shape).Then the mechanical performances in cores of beam-column joints under the action of load is analyzed,got the weak link of the structure and failure characteristics,used the finite element analysis software ABAQUS.The research can provide the theory analysis method for the overall work performance of special-shaped column frame structure under earthquake effect. |
