Purpose. The purpose of the webinar is to provide an overview of FEMA P-807, Seismic Evaluation and Retrofit of Multi-Unit Wood-Frame Buildings with Weak First Stories, developed by the Applied Technology Council for the Federal Emergency Management Agency (FEMA) in 2012. These guidelines provide cost-effective retrofit procedures for a vulnerable class of buildings with a history of poor performance in earthquakes. These buildings typically 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.

 Intended Audience. This webinar on FEMA P-807 has been designed for building officials, engineers, architects and others who need information on seismic retrofit of weak-story, wood-framed buildings.


Webinar Presenters.‎ David Mar‎ is the President of Mar Structural Design. His work emphasizes innovation in the areas of high-performance seismic design and sustainable design. His practice synthesizes creative engineering, rigorous analysis and research. David has worked with ATC on multiple projects: serving as the Project Technical Director of the ATC-71-1 Project, which produced the FEMA P-807 report, Seismic Evaluation and Retrofit of Multi-Unit Wood-Frame Buildings With Weak First Stories, serving on the Project Management Committees of the ATC-98 and ATC-99 Projects which discuss the use of high-strength reinforcement in earthquake-resistant concrete structures, and serving on the Steering Committee of the ATC-58 Project involving the methodology and implementation of seismic performance assessment of buildings. He has many years of experience and graduated from University of California, Berkeley with a BS and MS in Structural Engineering. 

Mike Korolyk is a principal at Tipping Structural Engineers. He has made substantial contributions to the firm's practice of engineering, weaving dynamic creativity, design aptitude, and the ability to effectively organize information with his masterful understanding of performance-based seismic design, analysis, and computer programming. His analytic strategies and tools have driven much of Tipping’s success in the last ten years. Mike was the primary force behind the analytic framework and execution of FEMA P-807, Seismic Evaluation and Retrofit of Multi-Unit Wood-Frame Buildings with Weak First Stories. Furthermore, Mike conceptualized and developed the Weak-Story Tool, the software program accompanying the report. Mike earned his BS in Civil Engineering and his MS in Structural Engineering at the University of California, Berkeley.

Professional Development Hours (PDHs). Each participant of the FEMA P-807 webinar will receive an electronic certificate documenting 1.5 PDHs. Each additional participant sharing the registrant’s computer may obtain PDH documentation using a form that will be provided as one of the handouts.

About *NETAP. This Webinar is funded by the Federal Emergency Management Agency (FEMA) National Earthquake Technical Assistance Program (NETAP), which is a mechanism for delivering direct assistance to the public to increase their knowledge and ability to analyze their risk, make a plan, and take actions aimed at reducing their earthquake risk and supporting overall community resilience. NETAP is not a grant or cooperative agreement program, but a contract managed by FEMA to rapidly deploy training and technical assistance to organizations and communities.

What's New?

What's New? The ATC Hazards by Location website allows the user to find site-specific basic wind speeds, ground snow loads, tornado design wind loads, and seismic loads used in the standards published by the American Society of Civil Engineers, National Earthquake Hazards Reduction Program, and International Building Code. This website was developed with the financial help of the ATC Endowment Fund, Federal Emergency Management Agency (FEMA), Insurance Institute for Business & Home Safety (IBHS), and Metal Building Manufacturers Association (MBMA), and is free of charge to users.
