Abstract:
Tests on reinforced concrete frame corners subjected to an opening bending moment (corresponding to tensile stresses in the reentrant corner) are described. Three fundamentally different reinforcement arrangements were tested. For high percentages of reinforcement, the load-carrying capacity of a common reinforcement arrangement proved to be low. Modified reinforcement arrangements resulted in corners that could transfer the same bending moments as the adjacent beams, even with balanced reinforcement.
