Research on Calculation Methods for Ductility of RC Beams with Near-Surface Mounted CFRP Plate Reinforcement

Abstract

Fiber-reinforced polymer (FRP) strengthening systems are widely accepted in engineering practice as means to enhance the flexural strength of RC members, but resulting in decreased ductility. To improve the flexural capacity of RC beams strengthened with CFRP plate, but also to ensure the enough ductility, a study was carried out. Putting forward the design method of CFRP embedded reinforcement beams based on ductility ability. The result of the study revealed that the method was reliable by the analysis of an example, and the method can be used in the design of reinforcement project.
