Description:	The original structural system for Barker Hall was a concrete frame with exterior precast concrete shear wall panels. During the 1989 Loma Prieta Earthquake these wall panels suffered moderate damage and after engineering analysis, the panels were found to be brittle and irregular with inadequate connection to the structural frame. To improve the seismic performance of the building, the design engineers decided to create a new seismic force resisting system instead of improving the old brittle wall panels. As a result, eight new concrete shear walls were constructed around the building perimeter supported by a new continuous post-tensioned concrete perimeter foundation. A unique feature of the retrofit was the use of fly ash (a by-product of coal burning that increases the durability of the concrete) in all concrete retrofit elements. This University of California Berkeley building was retrofitted as a part of the SAFER Program (Seismic Action for Facilities Enhancement & Renewal) which systematically reviewed, prioritized, and constructed building retrofits for all UC Berkeley owned and operated buildings.
