In order to realize the design concept of “strengthened column and weakened beam, strengthened connection joints and weakened components” and ensure the improvement of joints’ bearing capacity and the transfer of plastic hinges along beams far away from column ends, this paper proposes a new type of prefabricated beams with strengthen-weaken beam-column connection, and changes multiple parameters. Six connection joint models are designed for finite element analysis. The results show that: JD-1 is located far away from the column end according to the plastic development trend, which is in line with the purpose of transfer of the plastic hinges at the beam end. In addition, the whole column is barely damaged during the whole loading process of this connection joint, and quick recovery after the earthquake could be realized merely by replacing other related components of the joint in the later period. Changes of different parameters also have certain impact on the bearing capacity, seismic resistance and energy dissipation capacity of the joint.
