Madlum}, journal={KUFA JOURNAL OF ENGINEERING مجلة الكوفة الهندسية}, volume={13}, number={1}, pages={64-81}, year={2022}, abstract={Reinforced concrete slabs are common structural parts that may subjected to impact loads plusstatic loads. Reinforced concrete structures subjected to harsh environments in some time andbecause of the high corrosion resistance of Fiber Reinforced Polymer (FRP) bars; can used asa substitute for traditional steel. Up to failure, FRP bars behave in a linear-elastic mannerwithout yielding (brittle behavior), which necessitates a solution. Recently, there has been aproposed external bonding of Carbon Fiber Reinforced Polymer (CFRP) sheet on the tensionside of the slab to strengthen it. In this study, the number of CFRP sheet layers (one or two)and their configuration (covering the entire surface or only a portion of it) explored. Five(1550×1550×150) mm concrete slabs support all four corners of each one with simple supportand reinforced with Glass Fiber Reinforce Polymer (GFRP) bars casted. Four of themexternally bonded with CFRP sheets. All slabs tested under impact loads by dropping a 150kgmass from a height of 5m until cracks appeared. Displacement-time, strain-time, reactionforce-time, and acceleration-time explored and compared between slabs with variousconfigurations. The results show that increasing the layer number of CFRP on the tension sideof the slab develops impact resistance by delaying the appearance of cracks until third blow.In general, slabs with totally bottom CFRP layers provide better performance than otherconfigurations.
