摘　　要：西安某工业园区两栋框架结构塔楼设置大跨度钢连廊,跨度22m,采用钢桁架和楼面钢梁的结构形式。论文就钢连廊的结构布置设计、支座节点、腹杆弦杆相交节点等方面进行研究。并通过平面和空间模型计算结果比较,为国内类似的工程设计提供参考。Two frame structure towers in an industrial park in Xi’an are provided with large-span steel corridor with a span of 22 m,which adopts the structural form of steel truss and floor steel beam.In this paper,the structural layout design of the steel corridor,the bearing nodes,the intersecting nodes of the web chord are studied.Through the comparison of the calculation results of plane and space models,it can provide reference for similar engineering design in China.

关 键 词：钢桁架连廊 滑动铰支座 箱形截面 半多边形节点 次弯矩
