In order to investigate the seismic performance of the joint of a new PEC column-steel beam frame with a partial self-centering BRS energy-dissipation connection, the axial compression on the top of the PEC column and its layout were taken into consideration to design three reduced-scale specimens, and tests were conducted with low-cycle reversed lateral loading. Based on the experimental results, the seismic mechanisms of specimens were analyzed in terms of the load-carrying capacity, bending stiffness degradation, self-centering function, energy-dissipation capacity, and force-transfer mechanism of the joint. The results indicate that: (a)Partial self-centering BRS connectivity can provide self-centering functionality through dissipation of earthquake energy and reduction of structural response, and the main components are in the elastic state throughout the loading process. (b)The axial compression on the top of the PEC column significantly increases the initial bending stiffness, and accelerates the energy dissipation process, while the layout of the PEC column has little effect on the initial bending stiffness, stiffness degradation, and energy dissipation process. (c)The residual drift angle of specimen SYJ1 is less than 0. 005 rad when the loading drift reaches the interstory drift limit of 1/50 at the medium earthquake level and 0. 01 rad when the loading drift reaches the interstory drift limit of 1/30 at the maximum earthquake level, indicating its sound self-centering functionality. The self-centering functionality of specimen SYJ3 is slightly inferior to that of SYJ1, and the self-centering functionality of specimen SYJ3 is strong before the loading drift reaches the interstory drift limit of 1/50, but degenerates significantly in the late stage of loading.
