Steel bar/wire mesh mortar(SWM) reinforced concrete(RC)beams, steel bar mortar(SM) RC beams, and controll RC beams were produced for comparison study experimentally. Results indicate that SWM can significantly enhance the shear capacity of reinforced beams. Even though under low reinforcement ratios of wire mesh, the SWM reinforced beams still have good anti cracking property and relatively larger deformation capacity. Calculation formula for predicting the shear capacity and diagonal crack width of reinforced beams is also provided and show a basic agreement with the tested results.
