This study aims to assess the suitability of the MCFT-based shear design equation for predicting fatigue life of RC bridge deck slabs. Utilizing Takeda's previously established equations, which originated from an extensive experimental dataset of RC slabs subjected to moving wheel-type loading, this research adapts the MCFT-based shear design equation for fatigue life prediction. The results suggest that with modification to accommodate moisture and support conditions during fatigue loading, the MCFT-based shear design equation proves effective in predicting the fatigue life of RC bridge deck slabs.
