Dynamic responses of reinforced concrete slabs under sudden impact loading

Abstract Reinforced concrete (RC) slabs may be subjected to low-velocity impact effect in their service lives. In this study, it is aimed to investigate dynamic responses of two-way rc slabs. So, a total of 6 slabs with 500x500, 550x550 and 600x600 mm side lengths and having same thickness are both...
