Effect of Corner Angle on Efficiency of Reinforced Concrete Joints under Opening Bending Moment

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