Many numerical and experimental studies have been conducted to predict the fatigue life of RC slabs under moving load. Most of these works study the modeling of fatigue behaviors of RC slabs reinforced with deformed bars. The current study presents an experimentally verified numerical method to simulate the fatigue behaviors of RC slabs reinforced with plain bars under moving load. This numerical method is based on the bridging stress degradation concept. The bond-slip effect between a reinforcing bar and surrounding concrete is taken into consideration under repetitive load. The fatigue behaviors of RC slabs under moving load can be simulated through this numerical method. This method is also able to capture the cracking pattern, displacement evolution and rebar strain. The numerical method shows a good agreement with the experiments under static and moving load.
