Abstract
It is clear that there is some effect of the shear reinforcement with stirrups in deep beams. However the quantitative evaluation has not been enough and the mechanism has not been clarified. In this research, these are examined by the model experiments and the analysis. As a result, it is clarified that stirrups expand the concrete fracture area and the effect of the shear reinforcement is influenced by the shear span ratio and the shear reinforcement ratio. Based on the experimental results, the accurate calculation method of the shear strength of deep beams with stirrups is proposed.
