キーワード:Punching Shear Capacity., Vertical Pre-crack., Internal Crack Propagation

Regarding to reinforced concrete (RC) slabs, it is well known that fatigue process is strongly related to the occurrence of one direction vertical cracks, development to two direction vertical cracks and loss of shear transfer performance at vertical cracks. Many studies have been carried out regarding the fatigue life of RC slabs under moving loads. However, the impact of these vertical cracks related to fatigue process on the punching shear capacity of RC slab, which is a fundamental structural performance is yet to be clarified. Therefore, this study evaluated the punching shear capacity of RC slabs with several types of vertical cracks through experimental evaluation.
