ABSTRACT
A prefabricated beam-column connection with short strands (SSPC) in self-centering steel frame was proposed in this paper. The connection connects the frame column with the short beam portions on both sides through short post -tensioned (PT) prestressed strands, thus having avoided on-site aerial tension and achieving a prefabricated connection. Two full-scale test specimens were designed; low cyclic loading quasi-static tests and numerical simulations were also conducted. The study indicated that the hysteresis loops of the prefabricated beam-column connection with short strands showed an obvious double-flag shape and displayed a significant self-centering feature and satisfying energy dissipation ability. Aside from the occurrence of plasticity of the beam flange reinforcing plates and the beam flange at the two SSPCs closer to the column, the strain at the locations was small, resulting in an elastic state. The results of the theoretical formula derivation, finite element analyses, and experiments were very consistent.
