Abstract:
Tests of 54 reinforced concrete lightweight corners subjected to loads opening the corner. Effects of 28 types of reinforcement details on ultimate flexural strength, stiffness, and cracking reported, finding that use of two sets of mutually perpendicular diagonal reinforcement was promising method for developing flexural strength, reducing crack widths, and producing reasonably ductile behavior.
