Analysis of HSFG Bolted Joint Design on Steel Truss Bridges

本文分析了采用高强螺栓连接的桁架桥节点设计的要点,介绍了多种节点连接方式、构造形式和计算方法的优缺点及选用原则。具体阐述了连接节点处的各项计算内容,涵盖了节点板强度验算、拼接板尺寸验算及螺栓承载能力验算,为同类桥梁工程的设计提供借鉴。

This paper analyzes the main design points of HSFG bolted joints on steel truss bridges,then introduces the advantages and disadvantages of various models of joint points,structural forms and the principles of application,as well as the selection principles.And also the calculation details at the HSFG bolted joint are fully described,including the stress-checking computations of gusset plate,the size checking calculation of backing plate and the strength checking of bolts bearing capacity,which could provide reference for the design of similar bridge projects.
