摘要/Abstract

摘要： 应用非线性有限元方法研究了顺德风雨球场桁架拱结构稳定问题.使用牛顿-拉弗森法和弧长法对荷载-位移平衡路径进行跟踪研究,包括考虑了几何初始缺陷和不考虑几何初始缺陷两种情况时对结构的极限荷载和平衡路径的影响,从中获得了对桁架拱结构设计有益的结论.

关键词: 桁架拱结构；稳定性；非线性屈曲；极限荷载；

Abstract: This paper presents an elastic nonlinear buckling of a truss-arch structure.The effects of the perfect and the imperfect truss-arch structures on the stability behavior of structure are theoretically investigated by using the large displacement method and Newton-Raphson iteration.Some conclusions of the truss-arch structures design are drawn from the numerical results obtained in the study.

Key words: truss-arch structure； stability； nonlinear buckling； limit load；
