Highlights A FEM of UHPC grouted RC column-footing socket joints was established. Influencing parameters of joints performance were analyzed. An estimation method of moment capacity was proposed.
Abstract Socket connection is an effective connection method for assembling precast columns and adjacent components in accelerate bridge construction(ABC). In order to further enhance the efficiency of this connection type, an extensive numerical study of reinforced concrete(RC) column-footing socket joints was conducted by experimental data. The force transmission mechanism, the influence of parameters on the strength and failure state of the socket joints are revealed. It was found that the socket depth, longitudinal rebar ratio and axial load ratio have notable effect on the mechanical performance of the socket joints compared with other parameters. Base on the numerical simulation and experimental results, a calculation method for the moment capacity of socket joints was developed, which can accurately predict the moment capacity and failure mode of RC column-footing joints with socket connections. A design method of RC column-footing socket joints was also given for practical engineering.
