Abstract

Textile reinforced mortar (TRM) is a composite material composed of fibers as textiles attached to inorganic binders like cement-based mortars. TRM has been found to be a promising alternative solution to fiber reinforced polymer (FRP) in retrofitting structures. In this paper, reinforced concrete (RC) beams were strengthened in shear by TRM to investigate their behavior. ANSYS software program was used to generate the finite element analysis (FEA) models of TRM strengthened RC beams. The beam model results were compared to that of an experiment in the literature for validation and they were in good agreement. The parameters considered in the study were the effective depth of the beam, and various loading conditions. The results revealed that the beam depth had a significant impact on the ultimate load of shear deficient reinforced concrete beams strengthened with TRM. The load capacity improved, and the TRM shear contribution decreased with the increase in the beam's depth. Besides, distributing the load resulted in increasing the TRM shear contribution.
