Post-Tensioned Concrete Walls and Frames for Seismic-Resistance




Introduction This case-study describes an innovative application of post-

tensioned concrete construction in the new Davi d Br ower Center urban mixed-use development.

Situated in the heart of downtown Berkeley, CA, within 1km of the Hayward Fault, the new complex represents a model of integrated sustainable design. Rated LEED Platinum b y the U.S. Green Building Council and named for David Brower, one of the preeminent environmentalists of the 20th century, the center will provide office and meeting space for environmental advocacy and non-profit groups.

To protect the building against the high likelihood of a major earthquake, the structure integrates a unique combination of post-tensioned concrete walls and frames that improve performance, limit damage, and make more efficient use of construction materials.
