        abstract = {This research work aimed to investigate the shear capacity performance for three reinforced concrete deep beams model named as (DB01, DB02 & DB03) with different shear span to depth ratio. The grade of concrete is M40 and the grade of steel is Fe500. The deep beam is subjected to two point concentrated load to enable a better understanding of the effects of shear span–depth ratio, for this investigation ABAQUS FEA numerical software was used. The dimension of three test specimens (DB01, DB02 & DB03) is 1600 mm x200 mm x 600 mm. The effective span to height ratio l0/h is 2.0; the shear span–depth ratio is 0.3, 0.6 and 0.9, respectively. The deflection of mid-span, the characteristics of the full process of shear capacity, the failure mode and the load deflection deformation curve were examined. The test results showed that the failure mode of deep beams (DB01) with small shear span–depth ratio is due to diagonal compression failure and the failure mode of deep beams (DB02 & DB03) is due to flexure - shear failure. From this numerical analysis the shear capacity of the deep beams varies when the difference in the shear span to depth ratio gets vary, it shows that when the shear span – depth ratio decreases it gets fail under diagonal compression and when shear span – depth increase it fails under the flexure – shear.},
