Behavior and Load Capacity of Concrete Slab Reinforced by CFRP Bar and Strengthening by CFRP Laminates

Abstract The most common FRP materials used are carbon fiber reinforced polymers (CFRPs), and glass (GFRPs). use of CFRPs has grown rapidly in the construction industry, specifically structural retrofitting, due to their strengthening property CFRP. moreover high strength, lightweight, noncorrosive, easy-to-install materials. In present study, six concrete slab specimens included two control by traditional steel reinforcements other polymer CFRP bars without laminated strips. remaining four interiorly strengthened laminates strips with different scheme layouts named Type 1 2. were tested under a uniformly distributed load applied at top surface area each specimen up failure. parameters considered study amount layout. Test results indicated that strength carrying capacity failure mode differ based on reinforcement type presence
