苏州东环南延钢混组合梁结合段设计

Design on Joints of Steel-Concrete Composite Beam Bridge, East-ring Road South Extension Project in Suzhou

针对新建苏州东环南延钢混组合梁设计,重点介绍该桥的钢混结合段构造、计算等方面的工作。该桥钢混接头采用了PBL剪力板、剪力钉、纵向预应力钢绞线、纵向预应力粗钢筋等构造措施,形成了全截面连接承压传剪式的传力体系。关键部位受力分析结果对类似工程设计具有参考作用。

This paper presented a design on steel-concrete composite beam bridge,east-ring road south extension project in Suzhou focusing on structure,calculation of steel and concrete joints in the bridge.Steel and concrete joints were covered with PBL shear plate,welding studs,prestressed steel strand,prestressed thick reinforcement to form a integrated system for pressure transferring.
