Seismic Simulators (Shake Tables)

The MTS seismic simulator portfolio features a host of standard, pre-engineered and custom tables for evaluating everything from nonstructural infrastructure to structural components and substructures to model-scale and full-scale civil structures. Precise seismic loading in up to six degrees-of-freedom can be applied to a broad array of test articles to evaluate their behavior under real-world earthquake conditions.

Applications
