摘　　要：圆钢管结构由于其良好截面特性与外观,组成的桁架结构在公共建筑中大量运用,而在桥梁结构中应用较少。介绍某景观公园1座钢管桁架变高连续梁桥的总体设计与结构计算。该桥边跨平面分离成为2幅,呈“人”字形;桁架结构由上、下弦杆和支撑杆的腹杆组成,所有杆件采用圆钢管结构。节点连接采用内加劲板与相贯焊组合,轻盈独特、形态优美,为钢管桁架结构在人行景观桥中的应用开辟新思路,可供类似结构设计参考。Due to its good cross-section characteristics&appearance,round steel tube structures are widely used in public buildings,but less used in bridge structures.This paper introduces the overall design&structural calculation of a steel tube truss variable height continuous beam bridge in a landscape park.The bridge's side span is separated into two pieces,which are-shaped type;the truss structure is composed of upper&lower chords and web members of the support rods,and all the rods adopt round steel pipe structure.The joint connection adopts the combination of internal stiffened plates&intersecting welding,which is light,unique&beautiful in shape.It opens up new ideas for the application of steel pipe truss structures in pedestrian landscape bridges and can be used as references for similar structural designs.
