Shake Tables—What They Are & How They Help Structural Engineers

Beneath the table are mechanical devices called actuators that work together to simulate an earthquake. Typically, two actuators shake the table along the X axis, two shake the table along the Y axis, and four shake the tables vertically along the Z axis. The tables can also rotate independently along each of these three axes.
