Title: Fatigue Test on Welded Integral Joint of Transverse Truss of Baling River Bridge
Abstract: The Baling River Bridge is a single-span simply-supported suspension bridge with a main span of 1 088 m.The welded integral joint is used to connect the transverse truss and the main truss in the steel stiffening girder.The integral joint is a key structure and determines the safety of the bridge,but it is very complex in detail and has an undefined fatigue resistance.In order to investigate its fatigue reliability,a fatigue test is performed on a full scale model of the integral joint of the main transverse truss of the bridge.With an assumption of the load spectra represented by the standard fatigue vehicle in BS 5400,the test fatigue load is derived accounting for the multiple vehicle effect and the model scale.The test result shows that no cracks are detected in the model when subjected to two million stress range cycles,and the structure has an reliable fatigue resistance satisfying the design requirement.This type of integral joint is an alternative for long span truss bridges.
