Numerical modeling of TRC strengthened reinforced concrete beams under shear stress was studied. TRC strengthening consists of a mortar matrix reinforced by grid alkali resistant fiberglass textiles and mat. Initially, elements governing concrete beam behavior and different failure mechanisms were listed. Thanks to this; a time-economical, simplified but effective, numerical model on the macroscopic scale of a reinforced concrete beam sensitive to shear strain was studied. For this purpose, a parametric study of shear transfer coefficients and steel reinforcement anchor length was carried out. Finally, a macroscopic-scale numerical model of TRC composites and TRC strengthened reinforced concrete beam was proposed and validated based on the load-deflection curves and the pattern of cracking.
