摘要
国家体育馆屋面结构体系采用双向张弦网格结构,作为一种全新的结构体系,其节点的外形和受力更加复杂,设计过程具有很大的难度。介绍了国家体育馆撑杆上、下端及拉索端部节点的设计过程;对撑杆下端节点和拉索之间的抗滑移性能做了验算,并完成了足尺抗滑移试验。所提出的节点做法以及相关的试验数据可供类似工程参考。
The roof structure system of the National Gymnasium is bidirectional truss string structure. As a new structure system, the shape and structural behavior of the joints are more complicated, the design of the joints is extremely difficult. The design process of the post end joints and the cast steel joints at the end of the cable is introduced. The calculation and experimental study about the slide-reSistant behavior between the cable and the post down end joint are carried out. The joint plan and test data can be referenced by other similar projects.
