| Abstract: | Twelve restrained concrete rectangular beams without web reinforcement subjected to biaxial concentrated loads were tested so as to explore their shear mechanism and their behavior.Four main factors affecting the shear strength were analyzed:load inclination,the shear span-ratio,the ratio of maximum negative moment to the maximum positive moment, and longitudinal reinforcement ratio.Thereby the test basis for theoretical computation of the shear strength is provided. |

| Keywords: | biaxial flexural member shear strength without web reinforcement |
