摘要
采用ANSYS弹性壳单元分析模块,基于刚周边及上翼缘仅受侧向约束的假定,针对设置拉条的两跨连续檩条进行屈曲分析,考察了广泛参数范围下檩条的屈曲模态,同时从受力上给予合理解释。
Based on the assumption that the rigid periphery and the upper flange are constrained on- ly by lateral constraints, he paper conducts the buckling analysis of two-span continuous purlins with brace by the shell element modeling of ANSYS, and modes are investigated in consideration of a wide range of parameters. Meanwhile, the conclusion is given appropriate explanation in a perspective of force.
