概要 This paper describes an experimental study on high-strength short-span beams. The beams are constructed at the central core tube in a reinforced concrete high-rise building and expected to resist considerable part of seismic force by its high strength and ductility. Six specimens were fabricated with reinforced concrete and steel tube to satisfy the design demands. These were tested under seismic loading conditions. The beams with X shaped reinforcement showed good performance as expected. The beams with steel tube confinement showed much better performance. The load-deformation relationship can be estimated considering with flexure deformation, shear deformation, additional rotation by pull out of main bar at fixed end, and strain shift of main bar by bond degradation.
