Abstract
External wrapping with fibre-reinforced polymer (FRP) sheet has become a promising solution for retrofitting of damaged reinforced concrete slab in reinforced concrete framed structures as well as brick masonry structures due to various advantages. In particular, the flexural strength of a slab can be significantly increased by application of FRP sheets adhesively bonded to the tension face of the slab. It has been tried in the present work to study the behaviour of reinforced concrete slab strengthened with glass fibre-reinforced polymer (GFRP) laminates following the finite element approach using the software ANSYS. Previous research work based on the experimental observation reveals the fact that the extent of repair or strengthening of reinforced concrete slab with FRP laminates in terms of the load-carrying capacity or deformation under service load depends on different parameters such as the location of FRP laminate, the width of the FRP strips and thickness of the FRP.
