An investigation of anchoraged carbon fiber reinforced polymers bonded to concrete

Carbon Fiber Reinforced Polymers (CFRP) is used for strengthening or retrofitting of RC structures frequently at last decades. Although there are studies about the stress distribution between CFRP plates and concrete, there are very limited amount of studies about the behaviours of anchorages that are applied to ends of CFRP plates used for connection. Connecting diagonal strips of CFRP to columns and beams of masonry infilled RC frames is a significant problem. In this study, two different anchoraging techniques namely fan and standard type that are found in its place at literature are compared with their pros and cons. Type and the number of anchorages are the main investigated parameters. RC beams without any tension reinforcement that are manufactured with a notch at the constant moment region are used in this study. As a result, increase in the number of fan type anchorages should be kept limited, if any other precautions did not took in to account. But increase in the number of standard anchorages are improved the strength and behaviour positively
