| dc.description.abstract | Use of carbon fiber reinforced polymer (CFRP) in construction industry is getting better attention. This is partly due to CFRP’s superior characteristics such as high strength to weight ratio, Immunity against corrosion and high tensile strength features. A study on application of CFRP in form of grid is rare. Therefore, the present research work presents numerical investigation on use of CFRP grid as a reinforcing material in concrete slab. Experimental result reported in literature (Aljazaeri et al., 2020) was used for validation analysis using ANSYS non-linear finite element software program. Also, analytical formula from ACI was used to verify FE results. Further, parametric study on influential variables such as effect of concrete compressive strength, effect of bottom CFRP grid reinforcement layer and effect of volume fraction of CFRP reinforcement were conducted to get insight into flexural response of CFRP grid reinforced concrete slab. FEA results indicated that volume fraction of carbon fiber on carbon fiber reinforced polymer reinforcement and concrete grade has effect on structural performance of CFRP grid reinforced concrete. When volume fraction of carbon on CFRP reinforcement increased from control 20% to 30%, 40% and 50%, ultimate load resistance increased by 6.25%, 19.71% and 35.63% respectively. Similarly, when slab concrete compressive strength increased from 56 MPa to 60MPa the ultimate load resistance increased by 6.9% whereas reducing slab concrete strength 56 MPa to 40MP resulted in ultimate load resistance lost by 7.8%.
