摘　　要：针对宽幅大跨钢桁梁桥面系设计中主桁与桥面系共同作用过大的问题,介绍解决其共同作用的常规代表性方法,结合宽幅大跨钢桁梁工程实例,提出了改善结构受力状态的构造及施工措施,构造及施工措施对类似工程有直接参考价值。Aimed at the problem of the great interaction between the deck system and the main truss during the design stage,the typical solutions for these problem are presented.Combined with a wide span steel truss project,this paper presented the construction and construction measures to improve the stress state,which can serve as direct reference to the similar structures.
