FEMA P-58, Seismic Performance Assessment of Buildings, Methodology and Implementation

Speakers: Ronald O. Hamburger, Simpson Gumpertz & Heger and Jon A. Heintz, Applied Technology Council

Ronald O. Hamburger is Senior Principal at Simpson Gumpertz & Heger in San Francisco, California.  Mr. Hamburger has more than 35 years of experience in: structural design; seismic evaluation and upgrade; failure investigation; earthquake engineering research; building code and standards development; and education.  Mr. Hamburger serves as Chair of the ASCE 7 Committee, the AISC Connection Prequalification Review Committee and the NCSEA Code Advisory Committee.  He served as President of the Structural Engineers Association of California (1999-2000); the National Council of Structural Engineering Associations (2004-2005); and, the national Structural Engineering Certification Board (2007-2011).  He has authored more than 100 publications on the performance of structures in earthquakes and other disasters, structural design provisions of building codes, and the development and application of performance-based engineering methods.

Jon A. Heintz is Director of Projects at Applied Technology Council in Redwood City, California.  Mr. Heintz has more than 20 years of experience as a structural design and consulting engineer, and is currently responsible for project management, oversight, and quality control on the development of ATC products and publications.  A licensed civil/structural engineer in California and Alaska, he received his B.S. and M.S degrees in civil/structural engineering from the University of California at Berkeley.  His practice has included extensive experience in seismic evaluation and strengthening of existing buildings, advanced analysis methods, and structural engineering research.  He is a member of the ASCE Standards Committee on Seismic Rehabilitation, has been actively involved in the development of guidelines, codes, and standards for existing buildings, and has participated in post-earthquake damage investigations following the 1989 Loma Prieta, 1994 Northridge, 1999 Chi-Chi, and the 2010 Chile Earthquakes.


The Applied Technology Council (ATC) has recently completed a 10-year program under contract with the Federal Emergency Management Agency (FEMA) to develop a next-generation methodology for seismic performance assessment of buildings.  Collectively referred to as FEMA P-58, Seismic Performance Assessment of Buildings, Methodology and Implementation, the resulting products describe a general methodology and recommended procedures to assess the probable seismic performance of individual buildings based on their unique site, structural, nonstructural, and occupancy characteristics.  Based on the framework for performance-based seismic engineering developed by the Pacific Earthquake Engineering Research Center, performance is measured in terms of the probability of incurring casualties, repair and replacement costs, repair time, and unsafe placarding.  The methodology and procedures are applicable to new or existing buildings, and can be used to: (1) assess the probable performance of a building; (2) design new buildings to be capable of providing desired performance; or (3) design seismic upgrades for existing buildings to improve their performance.

This joint presentation will provide an overview of the ATC-58 project and the products resulting from that work, and will introduce the basic components of the methodology, including the types of assessment that can be performed, the results that can be obtained from those assessments, and concepts that are key to the methodology such as fragility, consequence, uncertainty, and the building performance model.
