基于ANSYS的门式刚架有限元分析研究

FINITE ELEMENT ANALYSIS OF PORTAL RIGID FRAME BASED ON ANSYS

研究基于ANSYS大型通用有限元软件对门式刚架结构进行了有限元分析。考虑抗风柱上端不同连接方式这一因素,对结构变形及支座内力情况的影响。结果表明,抗风柱上端不同的连接方式对结构变形几支座内力影响较小;同时还对结构进行了反应谱分析,最终得到了具有参考意义的结论。

A finite element analysis was conducted on a portal frame structure using ANSYS,a large-scale general finite element software.Consider the influence of different connection methods at the upper end of wind resistant columns on structural deformation and internal forces of supports.The results indicate that different connection methods at the upper end of the wind resistant column have little effect on the deformation of the structure and the internal forces of the supports;At the same time,response spectrum analysis was conducted on the structure,and a conclusion with reference significance was finally obtained.
