Experimental Study on the Shear Properties of Concrete Column Repaired by CFRP

Abstract

In this paper, shear study was carried out on four reinforced concrete columns in which two columns were reinforced by CFRP (carbon fiber reinforced plastics). The three main factors: shear span ratio, ratio of longitudinal reinforcement, CFRP paste quantity (layer numbers) were analysied since they affect the reinforced effect of CFRP. Through the experiment and simulation, the results indicate that the shear strength of CFRP strengthened concrete columns is obvious, which shows good agreement with experimental and simulation data.
