| Abstract | ||
| Using push-off specimens with shear plan length of 200mm and depth of 100mm, the influence of the addition of relatively widely spaced layers of steel wire meshes on shear transfer strength of reinforced concrete was experimentally investigated in this study. Eleven push-off specimens were fabricated and were divided into three groups depending on the number of layers of wire meshes crossing the shear plan. The other studied parameters were the shear parameter of the conventional stirrups (ρfy) and the angle of the plan of the steel wire mesh layers to shear plan of the push-off specimens. Using push-off specimens with shear plan length of 200mm and depth of 100mm, the influence of the addition of relatively widely spaced layers of steel wire meshes on shear transfer strength of reinforced concrete was experimentally investigated in this study. Eleven push-off specimens were fabricated and were divided into three groups depending on the number of layers of wire meshes crossing the shear plan. The other studied parameters were the shear parameter of the conventional stirrups and the angle of the plan of the steel wire mesh layers to shear plan of the push-off specimens. The test results showed that the use of relatively widely spaced (about 40mm) steel wire meshes has only trivial effect on shear transfer strength of reinforced concrete, where the percentage increase in shear transfer strength was about 8% in best cases. While using steel wire meshes in combination with conventional shear reinforcement (stirrups) gave better results, the percentage increase was about 13% compared to specimens reinforced with the same amount of stirrups but without steel wire meshes. | ||
