摘要

摘要: 压型钢板与檩条采用固定座连接时，屋面板对檩条的扭转约束作用很大，所以不能忽略。通过ANSYS有限元建模，分析杭萧钢构生产的HXY-478压型屋面板与檩条采用固定座连接时，屋面板对檩条的扭转约束刚度，并提出相应的刚度计算公式。为验证有限元对固定座模拟的准确性，通过考虑次翘曲的约束扭转分析，为固定座的扭转刚度提供理论分析模型，并与有限元模型的计算结果进行比较，两者吻合很好。

Abstract: The torsional restraint, which the steel sheets exert on the purlins, cann't be neglected when the profiled steel sheets connect the purlins with specially designed splints.It was mainly analyzed the torsional rigidity of the HXY-478 roof system developed by Hangxiao Steel Corp through FEM.With the results of the FEM, relevant stiffness formulas were proposed.In order to confirm the accuracy of the finite element model of the specially designed splints, considered the warping torsional theory, this thesis adopted a kind of theoretical model to analyse the splints and compared this theoretical result with the results of the FEM, and they coincided well.
