Numerical Approach to Shear Strengthening of Beams

Abstract

Finite element method (FEM) is used to study the behaviour of RC T-beams strengthened in shear with GFRP sheet under two-point loading condition. The finite element analysis is carried out in this study using ANSYS finite element software. Specimens without GFRP as control beams, designated as S0-0L, S300-0L and S200-0L and beams strengthened with GFRP sheets in U-jacket for specimens S0-1L-CT-U-90, S300-1L-CT-U-90 and S200-1L-CT-U-90 (Panda et al. 2012) are analysed. The main focus of the chapter is on the development of the model for full-size beams, elements used for the development of the model, the geometry of the models, loading and boundary conditions and comparison of results with experiment. The formulation of the FEM models is discussed in the following sections.
