Analysis on Fatigue Crack of Orthotropic Steel Bridge Decks

Ma, Rui / Dong, Peng / Xv, Zigang

Through the detection of the steel structure bridge for 7 years, the main distribution of cracks in steel box girder of steel structure bridge was presented. Through the numerical analysis of the steel box girder of steel structure bridge, the stress distribution of the diaphragms was obtained. The result of detection and the numerical analysis was compared, and showed that the cracks mainly appeared in the welding parts and the arc notch of the diaphragms. The cracks at the welding part mainly came from the welding defects. And the cracks at the arc notch of the diaphragms were due to the stress concentration.
