Seismic Design with Fluid Dampers in a Steel Frame Building

I'm Gregg Haskell of Haskell and Haskell of Knights Ferry, California.

These 30,000 lb. Taylor Fluid Dampers are used to dissipate seismic energy in a steel frame building.

This is the building, ready for the dampers to be installed. Total floor space is 300,000 square feet.

I designed an inverted chevron brace with a sliding box section. The dampers mount with one end on the sliding box, with the opposite end mounted to a welded down ground connection, called a deadman.

This is a finished damper installation, which the owner chose to leave exposed for occupants and visitors to see. A total of 62 Taylor Fluid Dampers were used for this project.
