STRENGTH AND BEHAVIOR OF REINFORCED CONCRETE OBTUSE CORNERS UNDER OPENING BENDING MOMENTS

Results of an experimental investigation of the strength and behavior of reinforced concrete obtuse corners under opening bending moments are presented. Five of the thirteen 145 deg corner specimens tested had different reinforcement detail; in the rest of the specimens the thickness or the length of one of the adjoining members was varied. From the observed crack and failure patterns and the ultimate strengths, adding inclined bars to loops at the joints was found to improve flexural efficiency greatly. The effect of varying the stiffness of the adjoining members significantly improved the efficiency and resulted in a gradual change in the mode of failure.
