分叉柱底铸钢支座节点受力分析

摘要

铸钢节点作为一种新型的节点形式,因其较强的适应能力被应用于大跨度空间结构中.本文通过非线性有限元分析,对分叉柱底铸钢支座节点进行研究,分析其在轴力作用下的应力分布情况、变形分布情况以及荷载位移曲线,在此基础上得出一些有用的结论.%As one of the new joint types, the cast-steel joint which has a strong adaptability has been widely used in many large span-space structures. In this paper, by the aid of finite element analysis software, authors research the cast-steel support joint at bottom of bifurcated column to analyse its stress distribution, deformation distribution of axial force and load displacement curve. By then, some useful conclusions are suggested.
