EXPERIMENTAL STUDY ON SEISMIC BEHAVIOR OF PRE-CAST CONCRETE BEAM-COLUMN SUB-ASSEMBLAGE WITH CAST-IN-SITU MONOLITHIC JOINT
With full-scale models,this paper investigated the seismic behavior of pre-cast concrete beam-column subassemblies with cast-in-situ monolithic joints under low-cycle reversed loading.The failure pattern,hysteretic characteristic,skeleton curve,ductility and energy dissipation,were analyzed.The result indicated that beam-column joints with longitudinal bars welded at the bottom of beams can meet the requirements of 'strong column weak beam,stronger joint'.
