126.6m跨张弦桁架结构的设计与研究

Design and research of a truss string structure with a long span of 126.6m

介绍了广州国际会议展览中心屋盖的大跨度张弦桁架结构的特点、结构分析和节点设计的情况,介绍了关于张弦桁架结构的刚度和水平动力特性方面的研究,以及弯曲钢管、相贯节点、铸钢节点等试验研究的成果.

In this paper, the characteristic of large-span truss-string-structure(TSS) of Guangzhou International Convention and Exhibition Center is introduced together with its structural analysis and joints design. Other study results for the stiffness of TSS, the dynamic characteristic in the direction of horizon, and experimental research on bended-pipe crossing joints of pipes and cast steel supports are also introduced.
