Strengthening of RCC Column Using CFRP

Abstract

In some buildings, when quality control is poor, the columns have a weak compressive strength, particularly in floor zone. Low compressive strength of the column member will lead to reduction in bearing capacity of column. This project is carried out to investigate the overall actions of P.C.C cylinder, strengthened with wrapped CFRP. From the literature study One or two of them will be a control specimen and the other six specimens were strengthened with CFRP. The main parameters studied from the literature research were the compressive strength, and the height of CFRP wrapped part of column. The results include mode of failure, ultimate load. All the test specimens were loaded to failure in axial compression and the behaviour of the specimens in the axial directions was investigated. Test results exposed that the CFRP wrap increases the strength and ductility of plain and RC cylinders expressively. The main conclusion of this project was, strengthening of column using CFRP and which may give good results of the column load carrying capacity.
