摘要
Abstract
Taking a pedestrian bridge as the research object,this paper introduces the architectural creativity and structural design of its bridge type,with a focus on the innovative points of the bridge structure.The main bridge is a single span through type simply supported space fish belly type variable height steel truss structure system,with the fish belly type truss with spatial inclination as the main load-bearing system.The X-shaped cross steel tie rods are used between the upper and lower chord rods and the vertical rods instead of the traditional cross rigid diagonal web rod connection method,and for the first time,the X-shaped cross steel tie rods are applied to bridge structures.The rigid column base connection node of the steel-concrete composite structure,which combines shear nails and PBL shear keys,is used for the position of the"double Λ-shaped"bridge pier column base.The bridge structure has reasonable stress and beautiful shape,reflecting the organic combination of shape and structure.关键词
