The Earthquake Shaking Table, dedicated in 1972, was the first modern Shaking Table and is still the largest six-degree-of-freedom (6 DOF) Shaking Table in the United States. The Shaking Table is configured to produce three translational components of motion; vertical and two horizontal, plus three rotational components; pitch, roll and yaw.
