Abstract:The shear strength calculating methods of RC columns strengthened with CFRP sheets, suggested in seven literatures of design standards, specifications and references, are summarized for comparison with the results of 33 tests. The reliability of the seven calculating methods and the shear contribution provided by the CFRP are analyzed. Based on the comparison with experimental results and the analysis, a practical calculating formula to determine the shear contribution of CFRP with enough reliability and simple calculation is put forward. The suggested calculating method can be referred for editing specification and used for construction design.
Keywords:CFRP  RC column  shear strength  effective strain
