摘　　要：应用ANSYS软件对梭形桁架屋盖结构进行特征值屈曲分析,在完成大量工程算例的基础上,对5个典型算例进行归纳总结,研究支座形式、檩条、上弦水平支撑对梭形桁架整体稳定的影响,提出改善梭形桁架整体稳定的设计建议。Eigenvalue buckling analysis of roof structures,which are composed of shuttle-shaped trusses is made by ANSYS.Based on the large number of completed projects,five typical examples have been summarized.The influence of support style,purlin,horizontal brace of top chord is investigated on integral stability of shuttle-shaped trusses in these examples.Some effective design measures are proposed for enhancing integral stability of shuttle-shaped truss.

关 键 词：梭形桁架 整体稳定 特征值屈曲分析
