摘　　要：台州火车站站台雨棚采用分叉式钢管柱与双向空间钢管桁架构成的刚架结构,屋盖为人字形柱面网壳。站台雨棚位于台风高发区且为四周开敞的圆柱形屋盖,风载为其主要荷载并通过风洞试验确定。屋盖结构设计时充分考虑风荷载对结构整体稳定的影响,对主要荷载工况作用下的结构进行线性和非线性屈曲分析。合理确定复杂构件计算长度系数、控制重要构件的应力,确保结构的安全性和经济性。选用屋盖构件截面、布置间距以及连接节点时充分考虑外露雨棚结构的美观要求,结构较好地体现了建筑形态和设计理念。The canopy structure of Taizhou Railway Station,located at typhoon-stricken area,consists of the spatial pipe truss,steel pipe tree columns and the cylindrical single layer latticed shell roof.The wind load,dete rminded by wind tunnel test,is one of the major load cases in the structural design due to the roof shape and all-round openness of the canopy.To ensure economy and safety of the structure,linear and nonlinear structural buckling analysis under various load cases were carried out to fully consider the wind load effect on the structural buckling.The stress of the main components were confined to the reasonable extent and effective length coefficient of columns with tree form were determined by buckling analysis.The component cross section,spacing and joints types were chosen to realize the architectural demand.
