 Earthquake shaking table

An earthquake shaking table is a device used to simulate the ground motions that occur during an earthquake. It is primarily used in structural engineering and earthquake research to test how buildings, bridges, and other structures respond when subjected to seismic forces. The table usually consists of a flat surface mounted on several hydraulic actuators or electric motors that can move the table in various directions (typically horizontal and vertical) to replicate the shaking of the ground.
