Abstract:
Fatigue is one of the main limit states in the design of shear stud connectors of steel-concrete composite bridges. In order to control fatigue in shear connectors, provisions mainly propose S-N curves. However, these curves have mostly been based on a limited number of experiments although many other S-N curves have been reported which are different. To address this issue, extensive data of conducted experiments on headed shear studs since 1950 are collected in this study, effects of various parameters on the fatigue behavior of headed shear studs are investigated. Finally, a three-level master curve is presented to evaluate the fatigue behavior of shear studs in steel-concrete composite bridge girders.
