Abstract: In this study, the effect of addition of layers of steel mesh with the dimensions 3×3 and 6×6 cm to a section of concrete reinforced beam on both of the maximum load and the amount of deflection as well as the width of the shear crack and flexure crack of the section has been studied. The six samples were examined; The two of which as reference beams. The two beams were added a layer of steel mesh with the dimensions (3×3 cm) to the sides and down, respectively as well as two samples have been added layer of steel mesh with the dimensions (6×6 cm). Deflection and width of cracks as well as the maximum load were measured, the failure pattern for each samples were also observed. Depending on the results it was concluded that adding steel mesh increases maximum crackload by 25% for dimensions (3×3 cm), on the other hand, the dimensions (6×6 cm), the increase was 7% when used at the bottom while up to 25% when used from the sides.
