Earthquake Protection Systems presents its major industrial projects incorporating seismic isolation technique.

Research projects related to the earthquake/wind protective building control techniques that are developed at the California State University, Northridge.

Video of a performance testing of a 6-story building model placed on an earthquake protector. The peak horizontal accelerations of the shake table are in the range of 1.2 - 30.6g. California State University Northridge. Requires apple quicktime.

Provides an example of a building designed to resist a magnitude 8 earthquake on the nearby San Andreas Fault.

Earthquake Protection Systems supplied friction pendulum bearings which satisfied the high seismic design requirements for the rebuilding of these viaducts after the 1999 earthquake.

Taylor Devices, Inc. provides information on the use of damping devices in large structures.

Viscous dampers distributed throughout an otherwise conventional structure can achieve the same result as base isolation at a significantly lower cost. This technical paper describes how to install viscous dampers in a structure and gives several examples.
