Numerical investigation of precast reinforced concrete beam–to–column joints by replaceable damper

This study aimed to investigate the precast reinforced concrete beam-to-column joints behaviors through replaceable damper under cyclic loading. The specimens have been embedded with steel reinforcement and specially shaped connectors. After application of loading, energy dissipation part has acted very well increased bearing capacity specimens. beam–to–column were designed analyzed compare (RC) specimen. analysis result loading based on controlled displacement method illustrated that specimen model shown a greater hysteric behavior than RC frame. PS-1 is passed 2.8% chord rotation approximately, which showed better performance, higher resistance efficiency PS–1 special connection elaborated finite element (FEM) simulated by ABAQUS software.
