To improve the hysteretic performance of prefabricated beam-column connections, a parametric analysis is conducted on an energy-dissipating damper connection composed of shear rods and a pin shaft. Based on the finite element method, the effects of the gusset plate spacing, the diameter of the energy-dissipating rods, and the distance from the rods to the pin shaft center on the seismic performance of the connection are investigated. The results indicate that increasing the rod diameter significantly enhances both the load-bearing capacity and ductility. When the rod diameter is increased from 18 mm to 22 mm, the peak load-bearing capacity increases by 18.5%, and the ductility coefficient improves by 27.7%. Increasing the gusset plate spacing enhances the energy dissipation capacity, but the peak load-bearing capacity decreases by up to 39.7%. Increasing the distance from the rods to the pin shaft center simultaneously improves the load-bearing capacity and stiffness; when this distance is increased from 100 mm to 120 mm, the load-bearing capacity increases by 10.0%. It is recommended to prioritize the use of 22 mm diameter rods and a center distance of 120 mm, while the gusset plate spacing should be selected between 5 mm and 15 mm according to the seismic fortification intensity. The optimized damper can effectively improve the seismic performance of the connection.
