In this study fatigue test on the steel grid composite deck is conducted for the evaluation of fatigue performance and serviceability. Deflection and crack width are measured at the end of each cyclic loading step. Test results show that maximum measured deflection and crack width are below the allowable values, and the tested steel grid composite deck exhibit acceptable fatigue performance and serviceability.
