COMPARATIVE STUDY OF EXPERIMENTAL AND ANALYTICAL BEHAVIOUR OF CRACKING AND DEFLECTION OF FRP STRENGTHENED RC BEAMS

Abstract

This paper presents the nonlinear Finite Element Analysis that has been carried out to simulate the behavior of
failure modes of Reinforced Concrete beams strengthened in flexure by Fibre Reinforced Polymer laminates. Total six
beams are modelled in Finite Element software ANSYS. Out of these Six, two beams are control beam without Fibre
Reinforced Polymer Strengthening and other beams are Glass Fibre Reinforced Polymer strengthened beams. From the
Finite Element modeling crack pattern and load vs deflection relationships until failure are obtained and compared
with the experimental results. Both the observational parameters showed good agreement with the experimental plots
with the analytical modeling for the beam without or with strengthening options.
