立柱、拉杆、斜撑与钢板梁组合异型景观人行桥方案设计

Schematic Design of Special-shaped Landscape Footbridge Composed of Column, Tie Bar, Diagonal Bracing and Steel Plate Beam

摘要:

随着物质生活的富足，人民对美的追求越来越高。传统的以功能为主、兼顾美观的桥梁设计原则逐渐转向功能与美观并重。以浦口公园人行天桥为例，介绍了立柱、拉杆、斜撑、钢板梁组合异型景观人行桥造型特点、结构组合方式和构件连接细节；区别于传统桥梁伸缩装置一般设置在桥梁墩台位置，桥梁伸缩装置设置在桥梁跨中，受力特点为不传递轴力，承担剪力、弯矩。

Abstract:

With the abundance of material life, the people's pursuit of beauty is getting higher and higher. The traditional bridge design principle that prioritizes functionality while taking aesthetics into account is gradually shifting towards giving equal weight to both functionality and aesthetics. Taking the footbridge of Pukou Park as an example, the modeling characteristics, structural combination mode and component connection details of the special-shaped landscape footbridge composed of columns, tie bars, diagonal bracing and steel plate beams are introduced. Differing from the traditional bridge expansion devices generally set at the bridge pier and abutment positions, the bridge expansion device is set at the mid span of the bridge, and its stress characteristics are not to transmit the axial force, but bear the shear force and bending moment.
