This presentation will introduce FEMA P-807, Guidelines for Seismic Retrofit of Weak-Story Wood-framed Buildings, developed by the Applied Technology Council for the Federal Emergency Management Agency (FEMA) in 2011. The Guidelines are cost-effective retrofit procedures for a vulnerable class of buildings with a history of poor performance in earthquakes. These buildings have weak ground stories with few walls, required to accommodate parking or commercial uses. The upper structure, with numerous walls, tends to be strong, but brittle. This relative weakness concentrates damage and deformations in the ground story. These structures are prevalent in the seismically active regions of the Pacific Northwest and California. The Guidelines have been developed to be easy to use while providing a practicable and cost-effective means to reduce damage and the risk of collapse. Sophisticated and extensive nonlinear response history analyses form the technical basis of the Guidelines. However, the procedure itself is straightforward and prescriptive.
