Abstract: As a widely used prestressed connector, high-strength bolts are seldom employed in self-centering structures because of their limited deformability. This paper connects disc springs in series with a high-strength bolt to form a prestressed disc spring bolt, which is then applied to steel column base joints. This paper theoretically derives the force-displacement relationship of disc spring bolts, establishes calculation formulas for parameters such as stiffness, load-bearing capacity and length of disc spring bolts, and conducts axial repeated tensile tests on 11 disc spring bolt specimens. The hysteresis curves, skeleton curves, energy dissipation capacities, and other data of the specimens are obtained from the tests. The results indicate that the disc spring bolts exhibit excellent elastic recovery and possess a significant energy dissipation capacity due to the friction between the disc springs. Increasing the initial pre-tension force and the number of disc springs in parallel can increase the energy dissipation, while increasing the number of disc springs in series and using B-type and C-type disc springs can decrease the energy dissipation. Based on the experimental data, a simplified simulation method using connectors for disc spring bolts is proposed. Further, numerical simulation hysteresis analysis is performed on the disc spring bolt-connected column base joint. The results reveal that the hysteresis curve of the disc spring bolt-connected column base joint exhibits a typical flag shape, demonstrating effective energy dissipation and self-centering capabilities. The proposed disc spring bolt can serve as a self-centering component for earthquake resilient column base joints.
