摘要	A single-yielding mechanism can effectively control the bending moment of a connection, and reduce the damage to the connection and column. In this study, a single-yielding precast concrete (SYPC) beam-column connection with a replaceable energy-dissipation connector (REDC) is proposed. The force transfer mechanism of the SYPC connection is discussed based on theoretical research. To verify the force transfer mechanism and repair ability of the SYPC connection and investigate the seismic performance of the SYPC connection, five low-cycle quasi-static loading tests are conducted on a single full-scaled specimen using five REDCs with different sizes. According to the test results, the seismic performance of the SYPC connection is discussed, including the bearing capacity, energy dissipation capacity, and stiffness. In addition, the single-yielding mechanism, neutral axis depth, beam elongation, and REDC strain in the SYPC connection are studied. The analytical and test results show that the structure of the SYPC connection is simple and reasonable, and that the path of the force transmission is direct and efficient. The SYPC connection provides excellent seismic performance, and is easy to repair after an earthquake. The single-yielding mechanism allows for control of the bending moment of the SYPC connection; this is beneficial to avoiding damage to the connection, e.g., damage owing to the overstrength of the beam strength and the alteration of the strength hierarchy in the structural system. Thus, it is conducive to realizing the design concept of strong-column and weak-beam.
