摘　　要：直立锁边金属屋面一般与檩条通过T形支托连接。通过分析金属屋面与T形支托连接的特点,计算T形支托的静摩擦力,用ANSYS软件对檩条及T形支托的有限元模型进行非线性稳定分析,研究直立锁边金属屋面与T形支托连接时对薄壁C型钢檩条侧向稳定性的约束作用。分析结果表明,直立锁边金属屋面T形支托连接可以阻止薄壁C型钢檩条的侧向失稳。Standing seam metal roof usually connects to purline with T brace. By analysing the feature of metal roof and T brace, the static frictional force is calculated, non-linear stability analysis of the purline and T brace is done by ANSYS software. The constraint of lateral stability of thin-wall channel steel purline is researched when standing seam metal roof T brace connects to it. The result shows the standing seam metal roof T brace connection can prevent lateral unstability of thin-wall channel steel purline.
