摘要
用非线性有限元法编制了稳定分析程序 ,进行了算例分析、验证。以跨度 3 5 4m、矢高 4 6m的弦支穹顶为例 ,用自编的程序和ANSYS进行了弦支穹顶的特征值屈曲、非线性屈曲分析 ,初始缺陷的影响分析和半跨荷载作用下的结构稳定性分析。同时 。
A nonlinear finite element program for stability analysis of suspendome is carried out.Some examples are analyzed by the program.The eigenvalue buckling,nonlinear buckling,influence of initial defect and stability features under half-span load of a suspendome with span of 35.4m and rise of 4.6m are analyzed using ANSYS and the compiled program.The influence of strut to the stability of suspendome is also discussed.
