Paper Title:
Fatigue Test Research on Welded Rib-to-Deck Connections in Steel Orthotropic Bridge Deck
  Abstract

In order to research the fatigue behaviors of the welded rib-to-deck connections in steel orthotropic bridge deck, 14 rib-to-deck connection specimens are designed considering the weld types, butt gap, welding method, and loading position as parameters. Fatigue test are carried out to obtain the fatigue loading cycle times of each specimen under different stress range. Based on the statistical regression analysis, the S-N curves and fatigue classification of the rib-to-deck connections welded with fillet weld and partial penetration weld are obtained respectively. The test results show that, the initial fatigue crack of the fillet weld is prone to appear at the weld root of the rib, while the initial fatigue crack of the penetration weld is prone to appear at the weld root of the deck.
