Shear Behavior and Bond Performance along PC Tendons in Prestressed Reinforced Concrete Interior Beam-Column Subassemblage under Bi-Lateral Load Reversals
Abstract eng: It is very important to clarify joint-panel shear failure mechanism of prestressed reinforced concrete (PRC) structures in which both PC tendons and longitudinal reinforcing bars are arranged. Therefore, bi-lateral load reversal tests of PRC three-dimensional and plane interior beam-column subassemblage specimens fabricated by post-tensioning method were carried out to investigate joint-panel shear behavior and bond performance along a PC tendon-sheath tube system. After column flexural yielding occurred for the three-dimensional specimen with coarse spacing of ribs along sheath tube surface a joint panel failed eventually in shear. As for the three-dimensional specimen with close spacing of ribs along sheath tube surface, the column failed in flexure without decay of story shear capacity.
