Effect of The Steel Wired Mesh On the Shear Behavior of RC Beams

Ferro-cement made of steel wired mesh and cement mortar is a method using for strengthening of existing reinforced concrete structures. In this study, the effects of the steel wired mesh on the shear behavior of reinforced concrete beams were investigated experimentally. For this purpose, three reinforced concrete beams having 150x300x2000 mm dimensions and different reinforcements were produced and subjected to four point bending tests. As a result, steel wired mesh improved the cracking mechanism of the beam by reducing the number of large cracks while increasing minor cracks. However, the use of steel wired mesh has caused early strength loss of the cracked beam. In the case of the usage of steel wired mesh in addition to the stirrups as shear reinforcement, the load bearing capacities, initial stiffness and displacement ductility of the reinforced concrete beams have significantly increased
