Benicia-Martinez Bridge

This bridge retrofit uses the world's largest seismic isolation bearings. The bearings can displace +53 inches while supporting loads of 5 million lbs. The ability of the Friction PendulumTM bearing design to avoid eccentric gravity loads in the truss structure, and the low profile bearing height, saved millions of dollars in retrofit costs, compared to the equivalent rubber bearing design.

U.S. Court of Appeals
Owner: General Services Administration
Engineer: Skidmore, Owings & Merrill
Seismic retrofit of this historic building using Friction PendulumTM bearings saved $7.6 million in construction costs and 80,000 sq. ft. of basement space, compared to the rubber bearing design. The project won the 1994 GSA Design Award for Engineering, Technology & Innovation.

San Francisco Airport International Terminal
Owner: City & County of San Francisco
Engineer: Skidmore, Owings & Merrill
Friction PendulumTM seismic isolation of this new building protects the expansive glass exterior walls and the long span roof trusses. Use of Friction PendulumTM   bearings, instead of the equivalent rubber bearings, saved 600 tons of structural steel. With over 1.2 million sq. ft. of supported space, it is the largest seismically isolated building in the world.
