    'Shake Table' Designed For Full Scale Earthquake Testing ..

    Theoretical simulations and scale models have only limited usefulness in predicting structural damage, so MIT researchers and their collaborators have prepared a conceptual design for a 30-by-30-meter shake table that can subject a full-scale building or other structure to the forces of a real earthquake.
