Either way the mechanics are simple. Using either a motor or by hand, you shove the table sideways, then "snap" it back. The thin sheet of water flowing over the table washes away any lighter material that "jumps" during the snaping action. Or at least that's the way some have described the action as being.

As shown in Fig. 5.12, this shaking table has an upper plate (25 tons) in square form (6 m × 6 m). This table is able to generate excitations with six degrees of freedom (three degrees in translation and three in rotation) using four vertical actuators and four horizontal actuators, each with a capacity of 1000 kN.

There are many studies on shaking table tests of LRBs for a building structure seismic isolation, but most of them are performed with the reduced scale LRBs [17,18,19,20]. For this reason, there are very few studies of the shaking table tests for the full-scale LRBs. ... and of equivalent stiffness (K eq) and critical damping ratio ...

For fair testing, place two marks on the table indicating the distance the pans can be shaken with an even force and speed over a set a time for the duration of the "earthquake". Next, have students test their structures one at a time on the Jell-O pan earthquake simulator. Shake the pan for the set time, force and distance.
