高性能耐候钢在钢板组合梁桥中的应用

Application of High-Performance Weather-Proof Steel in Steel Plate Composite Beam Bridge

常规组合梁桥由于其优越的受力性能、施工性能和良好的综合效益,被广泛应用,将高性能耐候钢用于常规组合梁桥中,可以充分发挥材料与结构两者的优越性能。论文以某免涂装支线上跨天桥为工程背景,介绍了免涂装耐候钢钢板组合梁的总体构造设计,并对耐候钢的局部细节设计进行了介绍,可为类似的工程项目提供参考。

Conventional composite girder bridge is widely used because of its superior mechanical performance,construction performance and good comprehensive benefits.Using high-performance weathering steel in conventional composite girder bridge can give full play to the superior performance of both materials and structures.Based on the project background of the overpass of a non painting branch line,this paper introduces the overall structural design of the non painting weather-proof resistant steel plate composite beam,and introduces the local detail design of the weather-proof steel,which can provide reference for similar projects.
