Full-scale shake table testing
A full-scale portion of a DIS Floor Isolation System, comprising two modules connected by stringers, was shake table tested at the University of Nevada, Reno.

More than 100 earthquake tests, including 75 DBE (Design Basis Earthquakes) and MCE (Maximum Credible Earthquake) motions were performed.

This suite of tests was extreme with maximum accelerations of 6g and floor displacements relative to the shake table of 18 inches. The results showed good agreement with the performance predicted by nonlinear computer models. Peak Accelerations and spectral accelerations were reduced by up to a factor of 7.
