Jonathan Barnett ~ Forensic Engineer For WTC7 Collapse

“We were surprised that the building [WTC7] collapsed, we being the team that investigated what occurred on that day. There was some damage to the Tower 7 caused by debris that hit it from Tower 1 but the damage was certainly not similar in scope or magnitude to that caused by the aircrafts hitting Towers 1 and 2. Normally when you have a structural failure you carefully go through the debris field looking at each item, photographing every beam as it collapsed and every column where it is on the ground and you pick them up very carefully and you look at each element. We were unable to do that in the case of Tower 7”.

[Dear Prof. Barnett,
I came across the following comment made by you to James Glanz of the New York Times of November 29, 2001, regarding the collapse of WTC 7 on September 11, 2001:
“A combination of an uncontrolled fire and the structural damage might have been able to bring the building down, some engineers said. But that would not explain steel members in the debris pile that appear to
have been partly evaporated in extraordinarily high temperatures, Dr.
Barnett said.”]…

Dr. Jonathan R. Barnett is a Professor at Worcester Polytechnic Institute (WPI). He holds appointments in Fire Protection engineering and mechanical engineering and is the co-Director and co-founder of the
WPI Melbourne Project Center. Dr. Barnett received his undergraduate, masters and doctorate from Worcester Polytechnic Institute. He is a fellow of the Society of Fire Protection Engineers (SFPE) and a member of the American Society of Civil Engineers, American Society of Mechanical Engineers, the National Fire Protection Association, the American Society of Testing and Materials Committee E-5, and the
International Association of Fire Safety Science. He has held appointments as the Editor of the SFPE Journal of Fire Protection Engineering, President of the New England Chapter of the SFPE and Chair
of the American Society of Civil Engineers Committee on Fire Protection.

His work and research in fire protection engineering is extensive, including most recently his participation in the Building Performance Assessment Team organized by the American Society of Civil Engineers for the Federal Emergency Management Agency to investigate the collapse of the World Trade Center Towers after the terrorist attacks of
September 11, 2001.

His current research centers on the mathematical modeling and computer
simulation of fires in buildings, ships and transit systems with an emphasis on heat transfer in structures and the use of computers in fire investigation and fire reconstruction. Recently he has developed a
prototype garment flammability test for the U.S. Navy Clothing and Textile Research Facility.
