摘要
根据筒体结构的受力特点 ,提出了筒体结构内力分析的拟平面法 ,并导出了拟平面单元刚度矩阵。采用本文方法 ,只需对现有平面有限元程序稍作修改 ,即可对筒体结构进行内力和变形分析 ,计算值与试验实测值符合情况较好。
A planar representation is developed in this paper to analyze tube structures su bjected to bending and torsion,and the p lanar element stiffness matrix is given according to the mechanical behaviors of tube structures.Based on the proposed m ethod,only a little modification should be made on the plane FEM program in orde r to analyze the spatial tube structures .The computed values for displacements a nd internal forces are considerably agre e with the test data respectively.
