Description:

Structural engineers have been implementing performance-based seismic design for decades.  Originally focused on safety, methods for performance-based design have evolved to include risk-based quantification of damage, repair costs, repair time, and environmental impacts with the publication of FEMA P-58 Seismic Performance Assessment of Buildings, Methodology and Implementation (2012 and 2018).  Now, with evolving concepts of resilience, and national attention on the concept of functional recovery, engineers are leading the way in shifting practice towards resilient design, with enhanced goals of limiting damage and building closure times, and maintaining specified levels of functionality.      

The FEMA P-58 methodology provides means for designing individual buildings to achieve enhanced performance objectives related to reoccupancy and functional recovery.  The Applied Technology Council is currently leading the FEMA-funded ATC-138 Project, which is enhancing the FEMA P-58 methodology to explicitly estimate functional recovery time as a performance measure.  This program will provide a brief overview of the FEMA P-58 methodology, describe enhancement of the method to assess functional recovery time, illustrate uses of FEMA P-58 in resilient design, and demonstrate applications of the methodology on a series of practical project examples.

1 – Jon A. Heintz, Applied Technology Council

Jon Heintz is the Executive Director of the Applied Technology Council in Redwood City, California.  He is a structural engineer with more than 30 years of experience in earthquake engineering practice and research, natural hazard mitigation, seismic evaluation and retrofit, and strategic planning on structural engineering research needs at the national level.  He is actively involved in committees for the development of guidelines, codes and standards for new and existing buildings, and has participated in post-earthquake investigations immediately following the 1989 Loma Prieta, 1994 Northridge, 1999 Chi-Chi Taiwan, and 2010 Chile Earthquakes, as well as damage assessments following Hurricanes Katrina and Rita in 2005.  He has led numerous ATC projects, most notably those leading to the publication of FEMA P-695, Quantification of Building Seismic Performance Factors, FEMA P-58, Seismic Performance Assessment of Buildings, Methodology and Implementation, and most recently, FEMA P-2090/NIST SP-1254 Recommended Options for Improving the Built Environment for Post-Earthquake Reoccupancy and Functional Recovery Time.   

2 – Curt B. Haselton, California State University, Chico

Curt B. Haselton, Ph.D., P.E. is the John F. O’Connell Endowed Professor of Civil Engineering at California State University, Chico, and the Co-Founder and CEO of Haselton Baker Risk Group (hbrisk.com) and the Seismic Performance Prediction Program (SP3); SP3 is a commercial tool to implement FEMA P-58 analyses, with the goal of making broad use of resilience-based design and risk assessment feasible in structural engineering practice.  Dr. Haselton's research is in the area of performance-based and resilience-based earthquake engineering, with focuses on damage and loss estimation, building code development, collapse safety assessment, ground motion selection and scaling, and the treatment of uncertainties. Dr. Haselton also chaired of the Building Seismic Safety Council team to rewriting Chapter 16 of the ASCE 7-16 building code.
