Evaluation of Performance of Shear Deficient Curved Beams Strengthened by Different Methods

Abstract

The study on experimental investigation and nonlinear finite element simulations of shear deficient and Glass Fiber Reinforced Plastic (GFRP) strengthened reinforced concrete beams are done. The responses, in terms of load-deflection behaviour, failure loads and crack patterns, obtained from numerical simulations are validated with that of the experimental investigations. The validated numerical models are then used for studying the efficacy and effectiveness of various strengthening schemes using epoxy impregnated GFRP fabric where the number of layers, orientation and distribution of fibers are considered as parameters. In this study investigations are done in curved beams. Modelling and analysis of curved beams is done in ANSYS 16.1 software.
