Abstract

In this paper analytical investigation was carried out for evaluating the performance of RCC beams retrofitted using BFRP wraps for enhancing shear strength. Numerical analysis tool ANSYS 2015 software was used. Two wrapping pattern considered were, U shape at shear zone and diagonal wrapping on side faces at ±45°. Beams were analysed for two point loading. Load deflection behaviour, ultimate load and deflection at ultimate load were compared. This paper also presents the effectiveness of BFRP as a retrofitting material in comparison to CFRP and GFRP.
