摘要
沈阳南站中央站房屋盖为大跨度空间结构,采用纵、横向交叉平面管桁架体系。纵、横向交叉平面管桁架体系为一种新型的大跨度空间结构体系,采用ANSYS软件对该中央站房屋盖结构进行了特征值屈曲分析以及同时考虑几何非线性和材料非线性的有限元分析,此外还考虑了缺陷对结构整体稳定性的影响。计算分析了屋盖结构弹性以及弹塑性屈曲性能,对此种结构体系的整体稳定性做出评价。
The longitudinal and transverse intersected planar truss which is a new type of long-span spatial structure system has been used in the long-span roof structure of the newly-built Shenyang South Railway Central Station.Buckling analysis and nonlinear finite element analysis were carried out by using ANSYS software,in addition,the influence of defects on overall stability was taken into consideration.The elastic and plastic buckling performance were studied in the paper,and the overall stability for the structure of such systems was evaluated.
