The shake table simulates earthquakes, and is able to reproduce any real event that has been measured to date, in order to test large dimension prototypes. The characteristics and the main specifications of the table are reported in the following.

Structure of the table: Honey-comb like steel network to ensure high stiffness and a reduced mass, compatible with the forces developed during the structural tests.

Guides: Supported with hydrostatic bearings to ensure minimum friction.

Electronic and control software: Closed loop control system based on displacement, velocity and acceleration.
