Experimental Study on Seismic Behavior of Pre-cast Concrete Structure with Cast-in-situ Integral Beam-column Joint Sub-assemblage

摘要

Based on the need of housing industrialization, using 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 also 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".
