Long Phan (Fed)

Dr. Long Phan is the Leader of the Structures Group in the Materials and Structural Systems Division (MSSD).  He began working at NIST as a member of the MSSD since 1984.  At NIST, he has conducted research on a wide range of topics, including performance of structures and materials subject to extreme loadings (fire, earthquake, hurricane wind and storm surge, tornado wind and debris, and ice-floes impact) and field investigations of damage to the built environment caused by natural or man-made disasters.  

He was an appointed member of the selected American Society of Civil Engineers (ASCE) and the U.S. Army Corps of Engineers team investigating the 9/11 terrorists attack on the Pentagon and coauthored the ASCE Pentagon Building Performance Report.  He published widely in the area of structural and material engineering, with over 100 technical papers in refereed journals and conferences.

He is the recipient of several NIST and external awards, including: the American Concrete Institute’s Arthur J. Boase Award (2019); the U.S. Department of Commerce Gold Medal (2014); U.S. Department of Commerce Silver Medal (2007); the U.S. Department of Commerce Bronze Medals (2006 and 1990); the American Concrete Institute’s Wason Medal (2004); and the U.S. Army Corps of Engineers’ Award for Valuable Contribution to the Pentagon Rebuilt Retrofit Program (2002).

Dr. Phan is a Fellow of the American Concrete Institute (ACI) and a registered Professional Engineer (P.E.) in the State of Virginia. He is also an adjunct professor at the Civil Engineering department of Catholic University of America. He is a Senior Member of RILEM Technical Committee HTC (High Temperature Concrete) and was the former chairman of the joint ACI-TMS Technical Committee 216 (Fire Resistance and Fire Protection of Structures), and a member of ACI 349 (Nuclear Structures), ASCE/SFPE Standard Committee 29 (Fire Design Calculation), ASCE 24 (Flood Protection), and ASCE 7-22 Wind Load Subcommittee, ASCE 7-16 Subcommittee on Tsunami Loads and Effects, and the former chairman of ASCE's Fire Protection committee.
