This study aims to optimize the carbon fiber-reinforced polymer’s (CFRP) arrangements rather than the amount of secondary steel reinforcements for strengthening reinforced concrete (RC) corbels, utilizing finite element (FE) analysis. While previous studies have only examined different types of FRP sheet arrangement in the absence or presence of equal amount of secondary steel reinforcements, this research fills a gap by comparing the effect of different configurations with the Externally Bonded Reinforcement (EBR) installation method and increasing the amount of the secondary steel reinforcements. Verification was conducted using a fully horizontally wrapped strengthened RC corbel with the secondary steel reinforcement. Results indicate that by just differing the arrangements of CFRP sheets, an increase can cause up to 33% in bearing capacity with the same volume of CFRP. However, by increasing the geometrical secondary steel reinforcement ratio (ρsh) from 0.18% of the verified model to 0.33% and 0.52%; the bearing capacity increases by 5.52% and 11.55%, respectively.

摘要

This study aims to optimize the carbon fiber-reinforced polymer’s (CFRP) arrangements rather than the amount of secondary steel reinforcements for strengthening reinforced concrete (RC) corbels, utilizing finite element (FE) analysis. While previous studies have only examined different types of FRP sheet arrangement in the absence or presence of equal amount of secondary steel reinforcements, this research fills a gap by comparing the effect of different configurations with the Externally Bonded Reinforcement (EBR) installation method and increasing the amount of the secondary steel reinforcements. Verification was conducted using a fully horizontally wrapped strengthened RC corbel with the secondary steel reinforcement. Results indicate that by just differing the arrangements of CFRP sheets, an increase can cause up to 33% in bearing capacity with the same volume of CFRP. However, by increasing the geometrical secondary steel reinforcement ratio (ρsh) from 0.18% of the verified model to 0.33% and 0.52%; the bearing capacity increases by 5.52% and 11.55%, respectively.
