| Abstract: | In order to investigate the static and fatigue behaviors of the welded rib-to-deck connections in steel orthotropic bridge deck,14 rib-to-deck connection specimens were designed considering the weld types,butt gap,welding method and loading position as parameters.The static test and fatigue test were carried out to obtain the fatigue cycle number 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... |
