Abstract
The strengthening of columns with circumferential wrapping of Carbon fiber-reinforced polymer (CFRP) sheets is one of the common applications for repair and rehabilitation. The paper presents the behavior of large-scale circular columns (150 x 1500mm) partially and fully wrapped with CFRP sheets are examined and compared with the unwrapped/reference column. Eighteen specimens in two groups M15 specimens and M20 specimens were cast by well known technique and tested under axial loading with the help of video gauge Imetrum system. The first three specimens from each group was the reference specimen. The next three specimens from each group were fully wrapped with CFRP sheets. The last three specimens from each group were partially wrapped with CFRP sheets. The test results are presents that the wrapping of CFRP was very effective in increasing the ultimate axial compressive strength and deformability characteristics of the concrete columns.
