箱形截面杆件三角形钢桁架人行天桥结构设计

南京市玄武大道樱铁村人行天桥设计为三角形钢桁架桥,所有杆件均为箱形截面,腹杆直接抵焊在弦杆上,不设节点板。重点介绍了该桥桁架节点构造设计中,在箱形弦杆内部设加劲隔板构造的方案;以及桥面板设计中,采用压型钢板组合桥面板的创新做法。这些关键技术的解决,使该桥结构设计具有一定的特色和优越性,值得推广和应用。

On Structural Design of a Triangle Steel Truss Pedestrian Bridge with Box Section Member Bar

Nanjing Xuanwu Ave.Yingtiecun Pedestrian Bridge is designed as a triangle steel truss bridge.All member bars are box sections without gusset plate,and web members are welded directly on chords.The truss panel joint design and the deck design of this bridge are focused on such as the plan of setting up stiffening division plate into box chord member,and the innovation method of adopting profiling steel plates to form bridge deck.The solutions to these key problems can make the bridge structure design possess...
