Outline of Final Research Achievements

In this study, experimental tests were conducted to evaluate shear strength of reinforced concrete members. By the experimental tests, following conclusions were obtained. Shear failure mode of reinforced concrete members failing in diagonal tension can be estimated with axial and shear stresses. Shear strength of a reinforced concrete column which was constructed with real scale was underestimated by conventional strength formula, and damage evaluation method provided by JBDPA underestimated the damage of the members with high-strength materials assumed by absorbed energy during loading.
