CFRP Strips on Punching Shear Strength Development of Bubble

So there is no sensible difference between the behaviour of a solid slab and Bubble Deck. But weight of bubble deck slab is low compared to solid slab, so punching shear capacity of bubble deck is very low. This study deals with what will be the effect of strengthening system such as CFRP to improve the load carrying
