Research on Seismic Performance of New Prefabricated Strengthen-weaken Beam-column Connection Joints

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