大跨钢桁架屋盖结构选型及节点抗震分析

Structural Seletion and Joint Seismic Analysis of Long Span Steel Truss Roof

文章对大跨度屋盖结构在较大荷载条件下的结构方案进行了选型。通过对比,变高度桁架相对等高度桁架具备相对较优的性能指标和经济性。另外,重点考虑了桁架与型钢混凝土柱连接节点的受力问题。设计通过对连接节点进行多尺度分析,确保了连接节点的受力安全。

The structural schemes of long-span roof structure under large load has been evaluated.By comparison,the variable height truss has relatively better performance and economy than the constant height truss.In addition,the stress of the connection between truss and SRC column has also been considered.Through the multi-scale analysis of the joint,the safety of the joint has been ensured.
