The addition structure at China Basin
utilizes an innovative application of seismic isolation
technology. Under the ownership of RREEF & McCarthy Cook the two
level, 175,000 square foot isolated addition has been built upon
the 1991 vintage three level post tension concrete Berry Street
Building at China Basin. This isolation technology is well suited
for this application given the susceptibility to earthquake
activity and meeting the current building code requirements under
the performance based design criteria. The seismic isolation
system provides lateral flexibility for the addition structure,
and during an earthquake dampens the ground motion energy being
transferred into the structure. The isolation system utilizes a
combination of 87 DIS lead rubber bearings and sliding isolators.
This sophisticated seismic isolation system is being used in
high-value structures and offers the building occupants and
operations a high level of safety and protection.
