摘　　要：采用非线性有限元法研究了冷弯薄壁Ｃ形檩条在蒙皮板侧向支撑及扭转约束作用下的静力工作性能。分析结果表明，蒙皮的侧向支撑及扭转约束作用可以大大减小檩条翼缘的侧向变形和截面的扭转变形，并提高其承载力。在分析结果基础上得出了一些重要结论。Nonlinear finite element meth od is used to analyse the static behavior of cold -formed light- gage C-purlins when diaphragm lateral- bracing and torsional restraint arc taken into account. Research results indicate that diaphragm bracing cffect on purlins can decrease the lateral deflection of purlin flange and the sectional rotation obviously and the parlin load carrying capacity is increased. Based on the research results, some important conclusions are obtained.
