STUDY ON ANCHOR BEHAVIOR OF CFRP PLATE TO CONCRETE
In this study, direct shear type bond test is conducted to examine the anchor behavior of CFRP plate to concrete. CFRP plate is bonded to concrete and anchored by five types of anchor method. In case of anchorage method by carbon fiber sheet, the debonding of CFRP plate is restrained after maximum load. In case of anchorage method by multilayer CFRP plate, effectiveness of anchor strength is not confirmed. In case of anchorage method by steel plate, most effective anchor behavior is obtained and maximum load is more than 3.65 times of the calculated bond strength without anchorage. In case of anchorage method by mortar spacer and carbon fiber sheet, maximum load is 1.09-1.72 times of the calculated bond strength. Even if load decreases once, load increases again to about 0.6-0.9 times of the maximum load. In case of anchorage method by side CFRP plate and carbon fiber sheet, bond strength increases by sharing the tensile force through carbon fiber sheet.
