| Research Abstract |
Experimental and analytical investigations were conducted regarding blast resistance of various composite PEFRC slabs and RC slabs with continuous fiber sheet strengthened. As a result, it was shown that a void slab and a hollow block of PEFRC combined with rapid construction have better blast resistance and reinforcement quantity of the sheet necessary for preventing spall failure of RC slabs can be estimated based on rupture energy of the sheet and modified-scaled concrete thickness of the slab.
