摘要
以承受大吨位载荷的门框形立柱为例,详述了结合线弹性屈曲分析和非线性静力有限元分析技术计算结构稳定性的理论和方法。为了更符合工程实际,计算中还考虑了结构材料的非线性。该方法适用于多种大型有限元系统,可直接用于计算实际工程结构的稳定性问题。
A finite element theory based on nonlinear buckling analysis method is discussed, which combines eigen-buckling analysis and nonlinear static analysis. Stability analyses of a portal frame with large working loads are given to demonstrate its validity. Material nonlinearity is also included to meet real-world engineering conditions. This method can adapt to most commercial finite method analysis systems for analyzing stability of practical engineering structures.
