桁架式铝合金人行天桥的应用与发展概述

铝合金人行天桥是铝合金材料应用于桥梁结构的产物。目前，其主要结构形式为桁架结构。近年来铝合金人行天桥在我国市政项目中频繁出现，成为继钢结构人行天桥后又一种新型人行天桥。现通过总结国内外已建铝合金人行天桥的信息，探讨铝合金人行天桥在国内外的发展现状及未来发展趋势。

Overview on Application and Development of Truss-type Aluminium Alloy Pedestrian Overpass

Aluminium alloy pedestrian overpass is the product of aluminium alloy material used in the bridge structure. At present, its main structural type is the truss structure. In recent years, the aluminium alloy pedestrian overpass is frequently used in the municipal projects of China, and has become a new type of pedestrian overpass after steel structural pedestrian overpass. According to the summarization on the information of the built aluminium alloy pedestrian overpass at home and abroad, the development status and the future development trend of aluminium alloy pedestrian overpass at home and abroad are discussed.
