The electro-hydraulic shaking table is a crucial experimental apparatus used in earthquake engineering to simulate real vibration condition [1], [2].Through various methods such as full-scale shaking table test [3], [4], reduced-scale shaking table test [5], [6], and shaking table substructure test [7], [8], researchers can assess the seismic behavior of test structures and …
Jafarian et al. (2020) investigated the influence of boundary effects on horizontal seismic waves using shaking table tests with rigid shear boxes. In dry and saturated sands, the acceleration response and settlement of the surface were more influenced by the boundary, and the hysteresis line of the shear box was consistent with the dynamic ...
Chen et al. [13] performed shaking table tests on a shaking table array comprising two shaking tables to research the effects of different coherent models on the seismic responses of utility tunnels. Researchers have investigated the seismic response of linear-shaped prefabricated utility tunnels using shaking table tests.
There are many factors affecting the work of the shaking table, among which the main stroke, the number of strokes, the concentration of ore feeding, the amount of ore feeding, the flushing water for the ore body, the lateral slope of the bed surface, and the nature of the ore feeding. (1) Stroke and stroke […]

Interaction effects between shaking table and structure are first studied by analysing the response of a two DOF (degree of freedom) oscillator with mechanical properties representative of the actuator-table-structure system. A single DOF viscoelastic oscillator representing the structural test specimen is then included in the analytical model ...
The layered shear soil box is widely used in shaking table tests, as it effectively minimizes boundary effects and allows for soil shear deformation(Li et al., 2023a; Lei et al., 2020). Additionally, 5 cm thick plates are placed on both sides of the model box to eliminate the influence of boundary waves generated by water vibrations.
