| Summary: | Strengthening of the structural members and frames is one of the engineering concerns, so this study will present some structural behavior of the reinforced concrete (RC) short column wrapped by carbon fiber reinforced polymer (CFRP) sheets under pure axial static load. The nonlinear finite element analysis (NLFEA) is conducted. ABAQUS/STANDARD software is used to analyze the reinforced concrete short column wrapped in CFRP and is compared the finite element analysis results to experiment results which are included in literature. Several aspects of the confinement effect on column response such as different in cross section size, number of CFRP layers, volumetric ratio of CFRP and column size effect are examined. It is found that externally bonded CFRP sheets are very effective in enhancing the axial strength and ductility of concrete columns. In order to validate the results which obtained by the finite element analysis, a comparison with experimental work is conducted. Inspection of results shows that there is a good agreement between the NLFEA and the experimental test results. |
