Abstract:
Structural elements subject to high out-of-plane shear and those needing confinement for ductility in the postelastic phase require concentrated transverse reinforcement. A T-headed bar has been developed that is inserted between the in-plane bars, then turned 90 degrees to lock behind hem. Ease of placement makes these bars economical, and the ability of one T-headed bar to replace several conventional stirrups facilitates concrete placement and vibration.
