Research Shake Table

Professor Andrew Smith of Columbia University will receive an ANCO 5-ton capacity, servo-hydraulic, horizontal shake table in September.  The 5-ft square R-142 table will be used for evaluation of building isolation and other building seismic enhancement devices, including passive and active control.

The uniaxial table is guided by very high stiffness preloaded roller bearings and zero-gap actuator flex couplings.  This guidance system provides virtually gap-free operation to high (100 Hz) frequencies and low maintenance.
