In recent years, resilient structures have gained widespread attention for their ability to withstand high-intensity seismic actions and rapidly restore functionality by replacing damaged components after earthquakes. The present paper proposes a novel dog-bone reduced beam section connection, incorporating V-shaped steel replaceable energy-dissipating components, and introduces its structural configuration and design concept. The finite element software ABAQUS was used to analyze the failure mode, stress, and strain distribution of the joint. This analyticalapproach was taken to reveal the failure mechanism, load transfer path, and energy-dissipation mechanism. On this basis, the influence of key design parameters (including thickness, material strength, and reduced dimensions) of V-shaped steel connectors and dog-bone reduced connections on the seismic performance of the joint was analyzed. The results indicate that (1) The integration of V-shaped steel replaceable energy-dissipating components, derived from traditional dog-bone replaceable joints, enables significant improvement of the energy-dissipation capacity and ductility of the joint. This configuration exhibits an equivalent viscous damping ratio ranging from 0.257 to 0.331. (2) The V-shaped steel connector undergoes significant plastic deformation during loading, thereby achieving the seismic design objectives of controlled damage and postearthquake replaceability. (3) The utilization of LY160 or Q235 steels is recommended for the design of dog-bone reduced connections and V-shaped steel connections. The thickness of dogbone reduced connections is advised to be 0.9-1.5 times the beam flange thickness, with dimensions of 25-30 mm. The thickness of V-shaped steel connectors is recommended to be 0.3-0.6 times the beam flange thickness.
