“…Uplifting is a form of seismic isolation because seismic demands are reduced to the supported structure through period elongation [2,3,6,[11][12][13][14]. However, the amount of period elongation is dependent on the amplitude of rocking displacement [2,6].…”

“…Accounting for deformation of soil and foundation, full-coupled soilstructure shaking table tests [5][6][7][8] and numerical analysis [9][10][11][12] were conducted and gained deeper insight into the seismic performance of structures. With soil intervention, vibration period of the whole model extends and thus influences authentic seismic responses of superstructures.…”

Based on branch substructure method, this article deduces motion equation of an equipment-structure-soil interaction system. The equation is converted and applied to a shaking table real-time substructure experiment. The equipmentstructure system is adopted as experimental substructure loaded by the shaking table. Meanwhile, finite element model of soil is adopted as numerical substructure after modal reduction. An equipment-structure-soil interaction scale model is designed and tested using shaking table under different earthquake records. Comparison shows good agreement of results of experimental and finite element methods. This work also proves validity and accuracy of the proposed experimental method.

“…Mergos and Kawashima [2] found that inelastic rocking of bridge pier has a significant isolation effect on the seismic response of the bridge. In recent years, many relevant experimental and numerical researches on the rocking seismic isolation mechanism have been carried out around the world [3][4][5][6]. It can be concluded that bridges with rocking foundations have advantages in seismic performance compared with other bridges, such as the fixed-base or the hinging-column bridges [7,8].…”

Abstract. The seismic isolation techniques of controlled rocking bridge pier is presented to improve seismic performance of the railway bridge in the earthquake-prone zone. In order to limit the lateral movement and overturning under the rarely strong earthquake, the inhibiting steel bar and prestressing tendon are used in the rocking bridge piers. The seismic performance of the two-different controlled rocking bridge piers are evaluated by quasi-static tests for two 1/10 scale model piers of a typical railway bridge pier with pile foundation. Through the hysteretic behaviors, it can be concluded that the rocking isolation model pier with the inhibiting steel bar shows better energy dissipation capacity, while the rocking isolation model pier with the prestressing tendon has higher anti-overturning capacity under strong earthquakes.
