Abstract
This paper present the review of analytical and numerical study of flexural and shear performance of retrofitted or strengthening of beam by fibre reinforced polymer (FRP). Now a day investigator prefer numerical and analytical study to minimize error which can’t reduce in experimental study, hence numerical study is more reliable than experimental study and analytical study less time consuming then experimental still having good agreement with experimental study.Almost all the software available in market are work based on finite element method (FEM) such as ANSYS, ATENA 3D and ABAQUS. Analytical study carried out by different author using FEM basedsoftware they found ultimate capacity of beam increased noticeably.Analytical investigation of reinforced concrete (RC) beam with FRP were carried out by number of investigator they all studied on different aspect, some of those worked on single layer or double layer of FRP , some of those worked on different pattern and thickness of FRP and then compared stress, strain and deflection with control specimen. For precise result by finite element method use fine mashing and appropriate material property. Bond behaviour between steel-concrete and concrete-FRP sheets/plate must be specify for accurate and realistic results.
