摘　　要：钢结构通廊在工业设计领域有着广泛的应用,工程设计中常将其简化为平面桁架进行计算。采用SAP 2000对一64 m跨下承式通廊进行空间计算,探讨了中间门架对通廊结构性能的影响。分析结果表明:设置中间门架有助于增加通廊的抗扭刚度,协调结构均匀受力,并能传递上弦平面的部分水平荷载,但会给相关联构件带来附加力,设计上应予注意。所得结论可供工程设计参考。Vestibule of steel structure was widely used in industrial design,and calculated with the model of simplified plane truss.In this paper,an half-through vestibule with 64 m span was spatially analyzed using SAP 2000.And the influence of intermediate rigid frames on performance of vestibule was discussed.The conclusions were drawn as following: Intermediate rigid frame could improve the torsion stiffness of structure and adjust the internal force to uniformity,and transfer a part of transverse load on plane of top chord;but it would bring additive force to the relevant components,which should be considered in design.The conclusions could be served as a reference of structure design.
