Abstract
This paper presents a new conception of shear behaviour of box concrete beams reinforced by composite fabrics. For this purpose, stirrups, wire meshes as shear reinforcement were used. Seven box section concrete beams were tested using two-point loading system. Beams with tensar wire mesh exhibited increasing in ultimate failure load, shear capacity and deflection with respect to beams used fiber-glass wire mesh instead of stirrups. Nonlinear finite element analysis was conducted using finite element program of ANSYS 14.5 to verify the experimental test program. An acceptable acceptance found between the experimental and numerical results.
