Berkeley Campus Retrofit: Barrows Hall

	Image-CR0299 Nearly completed retrofit of Barrows Hall, one of the first buildings retrofitted in recent campus-wide initiative. 8-story reinforced concrete frame and wall building was rated seismically "poor." Retrofit consists of new anchored reinforced concrete walls and foundations wrapping each end of the building and tied together by collector beams extending along the north and south face of the building at the upper floors. Retrofit was complicated by requirements to keep building in full use during work and to preserve window arrangements. (University of California, Berkeley)
