摘要
铝合金作为一种新型桥梁结构材料,具有轻质高强、耐腐蚀、施工便捷、景观效果好等特点,近年来在城市人行天桥中的应用越来越多。以海口市海秀快速路中某铝合金人行天桥为例,详细介绍铝合金天桥的总体布置及结构设计,建立天桥的有限元模型,进行结构计算分析并对设计合理性进行阐述,可为同类型桥梁设计提供参考。
As a new type of bridge structural material, aluminum alloy has the characteristics of light weight, high strength, corrosion resistance, convenient construction & good landscape effect. In recent years, it has been adopted more and more in urban pedestrian bridges. Taking an aluminium alloy pedestrian bridge in Haixiu Expressway of Haikou as an example, the general layout & structural design of the aluminium alloy pedestrian bridge are introduced in detail, the finite element model of the bridge is established, the structural calculation & analysis are carried out, and the rationality of the design is elaborated, which can provide reference for the design of similar bridges.
