Abstract:
The observed behavior of three reinforced concrete T-beams having differing stirrup- tie details during static cyclic inelastic flexure is summarized. The three types of stirrups investigated consisted of closed hoops and two types of U-shaped stirrups having different anchorage details. Results of the tests indicated that a U-shaped stirrup having 180 deg hook anchorages was capable of providing significantly the same amount of confinement as that provided by a closed hoop in flanged sections. Significant lateral confinement was provided by the flanges of the specimens tested.
