WebAug 29, 2024 · The most strengthening effect of CFRP on steel beams was observed in the case of concentrated load at midspan. Introduction Carbon fiber reinforced polymer (CFRP) has been extensively employed in the repair and reinforcement of structural members in recent decades due to its high strength-to-weight ratio, lightweight, and easy installation. WebThis paper investigates the feasibility of replacing steel bars with carbon-fiber-reinforced polymer (CFRP) bars in continuous reinforced concrete (RC) beams. A numerical model is introduced. Model predictions are compared with the experimental results that are available in the literature. A comprehensive numerical investigation is then performed on two-span …
WebNov 18, 2013 · CFRP was wrapped as a single layer around the beams within the entire tensile region and half of the sides. Results showed that the reinforced beams carried 80% more load [ 6 ]. Maalej and Leong studied the bonding behavior of CFRP and concrete blocks and discussed it in terms of analytical results. WebAug 1, 2024 · Introduce of CFRP can significantly reduce the crack widths and mid-span deflections of beams and improve the impact resistance of beams. In addition, the crack velocity in RC beam was inhibited effectively by CFRP, however, the inhibitory effect declined as impact velocity increased. Impact-resistance ability Digital image correlation
