Abstract The aim of the research is to study the structural behaviour of RC slabs strengthened with externally bonded fiber reinforced polymer (FRP). An experimental study has been carried out on ten slabs. Each slab of the tested slabs was 125 cm long × 125 cm wide × 5 cm thick, and was simply supported at its four edges. The slabs have been divided into two groups. The steel reinforcement ratio was 0.43% in the first group and 0.65% in the second one. Each group had its control slab (a slab without FRP). Two types of FRP material have been used; namely, carbon fiber reinforced polymer sheet (CFRP) and glass fiber reinforced polymer sheet (GFRP). The following parameters have been studied: the type of FRP material, the configuration of the strengthening FRP material, the amount (quantity) of the strengthening FRP material and the steel reinforcement ratio. A simple mathematical model has been used to predict the ultimate load of each slab of the ten slabs. Good agreement has been found between the experimental and theoretical results. |
