Prof. Fahim Sadek

Engineering Laboratory, National Institute of Standard and Technology, U.S.A.
Structural Design for Disaster Resilience

Dr. Sadek is the Leader of the Structures Group at the Engineering Laboratory, National Institute of Standard Technology. He received his Doctoral Degree in Structural Engineering from Southern Methodist University in 1996, and has worked at NIST since then. Dr. Sadek has extensive experience in finite element modeling and computer simulation of linear and nonlinear, static and dynamic structural response, particularly for structures subjected to seismic, wind, impact, and other extreme loads. His research specialties include mitigation of progressive structural collapse, structural dynamics and earthquake engineering, active and passive structural control, and wind engineering and structural reliability. He led the project "Baseline Structural Performance and Aircraft Impact Damage Analysis" as part of the NIST investigation into the collapse of the World Trade Center buildings. Dr. Sadek is the co-author of "Ground Motion and Response Spectra" in the Seismic Design Handbook (F. Naeim, ed., Kluwer Academic Publishers, 2001, pp. 47-124) and "Risk Considerations in Tall Building Design" in the Tall Buildings Reference Book (D. Parker and A. Wood, ed., Council on Tall Buildings, Routledge Publishers, 2013). He is also the author and co-author of more than eighty technical publications. Dr. Sadek is the recipient of the Department of Commerce's Gold Medal Award in 2005 for his role in conducting the NIST federal building and fire safety investigation of the World Trade Center disaster and the Department of Commerce's Silver Medal Award in 2007 for his role in conducting the NIST reconnaissance following Hurricanes Katrina and Rita. Dr. Sadek also received the Department of Commerce's Special Act Award for his contributions to the investigation of the World Trade Center Building 7 collapse in 2008 and the Building and Fire Research Laboratory Communication Award in 2002. In 2012, he received the ASCE's Moisseiff Award.

Abstract

This presentation provides a brief overview of research at the National Institute of Standards and Technology (NIST) on disaster resilience of buildings, infrastructure, and communities, including component programs and projects. NIST's efforts aim at developing the scientific basis required to enable technological innovation, improve predictive capabilities, and improve codes, standards, and practices for the cost-effective improvement of disaster resilience, including life-safety and reduction of property loss due to natural and man-made hazards. The fundamental idea underpinning this research is that disaster resilience can be enhanced by developing a robust capability to predict the effects of hazards on the performance of complex structural systems. This will be achieved by providing data to characterize the hazard, validated models to predict performance, metrics for measuring performance, acceptance criteria for differing levels of performance objectives, and mitigation strategies based on performance evaluation. Special emphasis is provided for two key research efforts related to structural design for disaster resilience currently underway at the NIST. These include mitigation of disproportionate collapse and fire performance of structures. For each effort, an overview is provided, followed by details of recent work carried out by the NIST including experiments and computational studies for the assessment of disproportionate collapse potential and the design and construction of the National Fire Research Laboratory (NFRL).
