Abstract
This paper presents the bending performance of reinforced concrete (RC) beams reinforced with carbon-glass fiber composite plates of different sizes under mechanical anchorage. The study consisted of the no-reinforced specimen and three reinforced specimens. The studies use a fourth point test method to evaluate the reinforcement effect of the mechanical anchoring carbon-glass fiber composite plate. The test was conducted by measuring the stress and strain of the carbon-glass fiber composite plates between expansion bolts, obtaining the stress distribution characteristics of the carbon-glass fiber composite plates under different load levels, and analyzing the change rule of stress in the plate. Analyze the plastic characteristics of the compression failure and the change of the ductility of the test members, and study the effect of mechanically anchored carbon-glass fiber composite plates reinforced concrete samples on the ductility of the original samples. The results of load-deflection and load-strain analyses show that carbon-glass fiber composite plate reinforcement is more effective. The test results show that the bolted anchorage carbon-glass fiber composite plates can improve the stiffness of the reinforced specimen and inhibit the development rate of concrete cracks in the tensile zone, which reflects the superiority of the mechanical bolted anchorage reinforcement form. The ultimate bending resistance of the mechanically anchored carbon-glass fiber composite plate is significantly improved. With the reasonable increase of the carbon-glass fiber composite plate, the flexural performance of the specimen beam was gradually enhanced. The computational analysis model of the bending reinforcement specimen was established, and the damage morphology of the member was analyzed. The researchers have proposed a theoretical model for calculating the positive section capacity of mechanically reinforced concrete members, and the test results are in good agreement with the theoretical calculation results of the bending capacity proposed in this paper.
