Abstract: Based on the design principle of "strong-columns and weak-beams", this paper proposes a single-yield precast concrete (SYPC) beam-column connection. Firstly, internal force analysis was conducted on the single-yielding mechanics and rotational stiffness of the SYPC joints, focusing on the beam end bending moment. Secondly, the replaceable energy-dissipation connector (REDC) was replaced once for the single SYPC beam column joint specimen, and three low-cycle quasi-static tests were conducted to study the hysteresis characteristics and damage state of the connection. Finally, the main influencing factors on the stiffness of SYPC joints were studied through the numerical analysis of SYPC joints, and corresponding design suggestions were proposed. The results show that the SYPC joint realizes the single-yielding mechanism, and the bending bearing moment at the beam end is completely controlled by the REDC yield force, which is conducive to the realization of the design principle of "strong-column and weak-beam". The damage of the joint is concentrated and easy to repair after earthquakes. The finite element model can better reflect the hysteresis characteristics of connections, and the design principle needs to balance the influence of REDC length on the ductility and stiffness. When the stiffness requirements cannot be met, it can be improved by increasing the cross-sectional area of REDC.
