均布荷载下三角网格圆锥壳的临界屈曲荷载分析

The Analyses of Critical Buckling Loads of Triangulated Lattice Dome Structures under Uniform Load Conditions

利用统计回归技术和非线性有限元分析,研究三角网格锥壳的屈曲行为,用来分析研究的三角网格锥壳刚度相对均匀、 承受的荷载均匀、边界条件也均匀。同时利用统计回归技术分析节点刚度对临界屈曲荷载的影响。本文编译自美国 TEMCOR公司提供的有关资料。

Statistical regression techniques and nonlinear finite element analyses are used to investigate lattice dome. The structures analyzed are triangulated spherical structures with relatively uniform grid pattems, under uniform load conditions and with uniformly support boundaries. In this paper Statistical regrassion techniques are also used to analyze the effect of joint stiffness on the critical buckling load.
