摘　　要：盐城机场候机楼改造工程钢屋盖采用空间三角形桁架结构体系,屋盖下部混凝土结构刚度不对称并且屋盖两端要求在较小的截面下达到较大的悬挑.本文介绍了该钢屋盖结构的结构设计,对解决结构刚度不对称造成的不利影响的不同方案进行了比较,结果表明在下部刚度突变处采用销栓的活接连接可有效地改善结构的受力.为达到建筑要求并兼顾屋面结构布置,采用特殊的主檩条截面,对该截面的构造安装及整体稳定性等问题进行了探讨,为类似工程提供有价值的参考.The roof of Yancheng Airport Lounge adopts the form of triangular space truss structure . The rigidity of the concrete structure under the roof is asymmetry and the roof ends are designed to be large cantilever while the construction members are confined in a small section. This paper introduces the design of this project. Two schemes accounting for the disadvantage influence on the roof structure resulted from the asymmetrical rigidity of concrete structure are compared, and the results indicate the endurance state of the roofcan be effectively improved by adopting the foxtail connection at the rigidity mutation place. Special purlin section is designed for satisfying the architecture request and regarding the construction convenience of the roof, and the installment and stability of the purlin section are studied.
