Analysis on Crack Types and Causes of Junshan Bridge’s Steel Box Girder Orthotropic Plate

Abstract:

The fatigue cracking of orthotropic plate is a fatal problem for the long operation of steel bridge safely. There are numerous fatigue cracks appearing on Junshan Bridge, which locate mainly on diaphragm, U-Rib and fillet weld between the U-Rib and deck. Based on the location of fatigue cracks, the paper analyzed the causes of fatigue cracking from three aspects of mechanics cause, detail design and manufacturing factors, providing scientific basis of future health monitoring for bridges.
