Abstract:
Results of an experimental investigation of the effect of the corner angle on the strength and behavior of reinforced concrete corners under opening bending moments are presented. Twelve specimens divided into two groups with two reinforcement details and the included angle varying from 60 to 180 deg were tested. From the results obtained, and from those reported by others, it was found that the efficiency of the joint is significantly affected by the angle and is at its minimum when at 120 deg. Theoretical analysis using finite element method (FEM) confirms the same variation of the diagonal tensile stress concentration with the angle.
