FEMA Mitigation Best Practices: UCSF Medical Center Seismic Saw-Cut Mitigation Project   [open pdf - 26KB]

This document is part of the Federal Emergency Management Agency (FEMA) Best Practices Portfolio. The Best Practices Portfolio is a collection of true stories about people and communities who have experienced disasters, and what mitigation they used to survive, rebuild, and prepare for disasters. This Best Practice Story describes, "The University of California San Francisco (UCSF) Medical Center Parnassus serves as the main campus for UCSF's medical program, as well as a Children's Hospital, several research labs, and the center for the Dental and Nursing programs. Located in San Francisco near Golden Gate Park, this fifteen story structure is in a neighborhood that has a high likelihood of significant damage after a major seismic event. During the last major seismic event, the Loma Prieta earthquake of October 1989, the Medical Center building and the Medical Sciences Building (MSB) experienced significant damage to the expansion joint between them. An engineering analysis revealed that due to the differences in the relative stiffness of the structures, they would perform better independently than tied together. Project Seismic Saw-Cut will physically sever the structural connection between the two buildings and install a seismic expansion joint in the gap. This improves the chances of both structures surviving a seismic event with minimal significant structural damage. The same change would be implemented on the link between the MSB and Cole Hall (a 408 seat lecture hall adjacent to the MSB)." This and other individual FEMA Best Practices documents are also combined in "Mitigation Best Practices: Public and Private Sector Best Practice Stories for All Activity/Project Types in All States and Territories Relating to All Hazards [August 10, 2011]," which can be accessed at the following link: [https://www.hsdl.org/?abstract&did=683132]
