Abstract

This study presents experimental performance and modes of failure of reinforced concrete (RC) beam strengthened with externally (bottom side) bonded glass fiber reinforced polymer (GFRP) strip. Experimental results compared with presenting finite element modeling of R C beam using ANSYS software. The finite elements model uses a discrete approach to reinforced concrete and three dimensional layered elements to model the fiber reinforced polymer (FRP) composites. The comparison is made for load deflection curve at midspan and mode of failure. The result obtained from finite element analysis was calculated at same location as the experimental test of the beams and accuracy of was compared. The load–deflection curve from finite element analysis is good agreement with the experimental results
