摘要
对脚手架立杆建立单杆计算模型,并引入初始缺陷,建立有限元分析模型进行非线性屈曲分析.通过分析长细比、半刚性节点和初始缺陷对单杆稳定承载力的影响,提出脚手架立杆是缺陷敏感构件,给出了一种简捷的初始缺陷模拟方法.
In this paper, a single rod calculation model is established for scaffolding poles, and initial de fects are introduced. The finite element analysis model is established for nonlinear buckling analy and a simple initial defect simulation method is given
