Numerical study on shear behavior of gfrp reinforced concrete using textile grid as shear reinforcement

Abstract

This paper presents a numerical study on the shear behavior of GFRP-reinforced concrete beams using a textile grid as shear reinforcement, conducted with ATENA software. The results of the finite element model demonstrate good agreement with experimental findings regarding the load-displacement curve, load-bearing capacity, failure modes, and crack distribution. Based on the proposed model, the influence of the type of textile grid on the load capacity of GFRP-reinforced concrete beams was investigated using two types of fiber: carbon and glass. The results indicate that the load capacity of GFRP beams with carbon fiber increased by 7.08% and 17.03% compared to those with glass fiber.
