Influence of Stirrup-Tie Shape on Inelastic Cyclic Response of Flanged Reinforced Concrete Flexural Members

Three reinforced concrete flanged sections (T-sections) having different shapes of shear reinforcement were subjected to cyclic inelastic flexure representative of what framed structure members might-be forced to endure during a severe earthquake. The different types of shear reinforcement consisted of closed hoops and two types of U-shaped stirrups, neither having been supplemented with cap ties. This report documents the experimental work, presents data obtained during tests (including energy dissipation capacities) and discusses the implications of test results on possible changes in reinforcement details for frame structures in seismic regions
