摘要
外海港口中的钢桁架桥受风荷载作用较大,风荷载甚至可能成为钢桁架桥的主要荷载。而《港口工程荷载规范》和《公路桥涵设计通用规范》两种规范对风荷载的计算模式存在一定差异。通过对某码头上一座90 m钢桁架桥的计算比较,分析不同规范下的参数取值及结果,给出对横向风荷载计算的建议。
Steel truss bridge suffers heavy wind in open sea. The wind load even plays a crucial role on the bridge. It has two different calculation methods for the wind load in accordance with two different codes General Code for Design of Highway Bridges and Culverts and Load Code for Harbor Engineering. The article is to calculate and analyze the cause of the difference by two codes on the basis of a 90 m long steel truss bridge in a wharf project, and give suggestions on the future design.
