要旨 Circular cross-sectional reinforced concrete (RC) members such as piers or piles are often used in aggressive environment. Corrosion of steel rebars harmed the lifespan of these members. As an alternative substitute, CFRP rebars present advantages over normal steel rebars. However, the force transfer between CFRP and concrete is still ambiguous. Through analyses with a material nonlinearity, this paper presents how different surface characteristics of CFRP rebar affect the strain distribution of concrete and CFRP reinforcement leading to different performance of CFRP strengthened RC beams.
