摘要
我国某公铁两用特大桥（Ｗ桥）将采用混凝土桥面系－钢桁结合梁。目前，国内外现有的组合结构规范中还没有桁梁结合梁的内容。本文研究了桁梁结合梁的受力特征，针对Ｗ桥的具体情况试验研究了栓钉的承载力和布置方案，该成果已用于Ｗ桥的设计。
Concrete steel truss composite girder is a new type of composite structure, which will be used in a combined highway and railway bridge(W Bridge) in China. Nowadays none of the design code is for this type of composite girders. The characteristic of it and the strength, arrangement of its shear connectors are studied. The research results are being used in the design of W Bridge.
