钢管桁架人行景观桥的设计

Design of Steel-tube Truss Landscape Footbridge

摘要:

兼顾轻盈、通透、简洁明快的景观要求，同时满足跨径较大、梁高较小、平曲线半径较小、处于高地震区，以及地质条件较差等诸多限制条件，在景观人行桥的设计中采用钢管桁架结构（部分构件采用钢管混凝土加强）。通过对某公园内一座管桁式人行桥的设计，给出了合理的结论，并进行了部分参数的敏感性分析，希望为今后同类型景观桥梁的设计提供参考。

Abstract:

Considering the landscape requirements of lightness, transparency, conciseness and vividness, also meeting the numerous limiting conditions of larger span, lower beam height, smaller horizontal radius, locating at high earthquake region and poor geology, the steel-tube truss structure (concrete filled steel tube to reinforce the partial structures) is used in the design of landscape footbridge. The reasonable conclusion is given through the design of a steel-tube truss footbridge in a park. And the sensitivity analysis on the partial parameters is carried out, which hopes to provide the reference for the design of the similar landscape bridges in the future.
