 In recent years using polymer materials in strengthening and retrofitting the concrete Elements is on the process. Fibre reinforced polymers (FRP), have emerged as an alternative solution to traditional materials for strengthening and retrofitting structures, especially in existing structures which need to up build or to change the usage. In attempt to increase strength and ductility of concrete column load bearing elements through confining systems the FRP membranes have become a familiar solution. The studies of Theoretical, Experimental And Finite Element Analysis are carried out. In these project column size of 150mm and 600mm height. The columns are retrofitted by carbon fibre reinforced polymer sheets. The theoretical calculation are performed based on the codal provision and literature available. In the Experimental studies of short column models are cast and tested under compressive test up to failure. In FE analysis the concrete columns with and without CFRP model are analyzed. The result of Theoretical, Experimental and FE analysis are tabulated discussed and conclusions are shown
