Finite element analysis of frp strengthened RC beams using ansys

This paper presents the nonlinear Finite Element Analysis (FEA) that has been carried out to simulate the behaviour of failure modes of Reinforced Concrete (RC) beams strengthened in flexure and shear by Fibre Reinforced Polymer (FRP) laminates. Four beams were modelled in FEM software using ANSYS. In those four beams, two beams were control beams without FRP and other two beams were Carbon Fibre Reinforced Polymer (CFRP) strengthened beams. A quarter of the full beam was used for modelling by taking advantage of the symmetry of the beam, loading and boundary conditions. From the analyses the load deflection relationships until failure, and crack patterns were obtained and compared with the experimental results available in the Literatures. The load deflection plots obtained from numerical studies show good agreement with the experimental plots reported by Balamuralikrishnan Antony Jeyasehar, and Amer M. Ibrahim Mohammed Sh. Mahmood. There was a difference in behaviour between the RC beams strengthened with and without CFRP layers. The crack patterns obtained in FEA in the beams were also presented. The use of computer software to model these elements is much faster, and extremely cost-effective. Therefore, modelling of experimental beams can be adoptable in ANSYS. Validation of experimental results can also be done using ANSYS.
