摘要
钢结构应用于大中跨度天桥具有极强的优越性。本文总结了钢结构近年来的发展状况,通过两个不同结构形式的天桥实例,对比分析出钢桁架人行天桥在结构性能、施工工期和经济性方面的优势,并介绍了钢天桥的施工技术要点。
Steel structure has outstanding superiority in application of large and intermediate span pedestrian bridges. This paper introduces steel structure development in recent years, and construction skill essentials depend on the superiority of steel structure in structure, construction period and economy by comparison of two different structure pedestrian bridges.
