3D-BASIS used for analysis and design around the world: Recent Applications

Buildings/Structures Analyzed and Designed using 3D-BASIS suite of programs

San Francisco International Airport Terminal

San Francisco’s International Airport Terminal is supported 267 seismic isolation bearings. This landmark building is protected from a major earthquakes in California primarily due to seismic isolation. 3D-BASIS suite of programs were used for the analysis and validation. The analysis and design was performed by Skidmore Owings and Merrill.

US Court of Appeals Building – San Francisco

The 100-year-old Court of Appeals Building in San Francisco, California was retrofitted after the 1989 Loma Prieta earthquake using seismic isolation bearings and was fully reoccupied in 1996. Sensors placed below and above the isolators allow measurement of the effectiveness of the system. 3D-BASIS program was used for the analysis and validation. The analysis and design was performed by Skidmore Owings and Merrill.

New San Bernardino Justice Center 

The Justice Center is landmark 400,000 square-foot building in San Bernardino city is located in one of the most active seismic regions in the U.S. The seismic isolation system consists of 69 bearings located above the base mat foundation.   3D-BASIS suite of programs were used for the analysis and validation. The analysis and design was performed by Skidmore Owings and Merrill.

The new, 450,000 square foot medical facility located just two miles from California’s San Andreas fault is supported on 176 seismic isolation bearings. 3D-BASIS suite of programs were used for their analysis and validation.

 

Sakhalin offshore platforms I and II

Sakhalin offshore platforms I and II, are supported by four large seismic isolation bearings.  The topsides steel deck sits atop of the four bearings. The four bearings are supported by four massive concrete columns on massive concrete gravity structure. 3D-BASIS suite of programs were used for their analysis and validation.

Many other structures have been analyzed and designed using 3D-BASIS suite of programs. These include airport building complexes and LNG tanks in Turkey, Peru, and other countries.
