This study is to quantitatively estimate the effects of variables related to shear behavior of deep beam. Among many variables affecting shear behavior, three are selected for the study: shear span-to-overall depth ratio, section depth, and clear span-to-overall depth ratio. Total of 18 specimens were designed and tested. Their section width, concrete strength, and shear
span-to overall depth ratio were 160mm, 23.5MPa, and 0.5, 0.75, 1.0, respectively. Loading was acted on two symmetric points along the specimens. The results is which was observed that the diagonal crack and failure mode were significantly influenced by shear span-to-overall depth ratio and section overall depth, Also, It was conducted the RC deep beam test in order to clarify
the size effect: that is the shear strength which decrease with the increase of effective depth.
