NIST and the World Trade Center
The collapse of New
York City’s World Trade Center structures following the terrorist
attacks of Sept. 11, 2001, was the worst building disaster in recorded
history, killing some 2,800 people. More than 350 fire and emergency responders
were among those killed, the largest loss of life for this group in a
single incident.
In response to the
WTC tragedy, the National Institute of Standards and Technology conducted
a 3-year building and fire safety investigation to study the factors
contributing to the probable cause (or causes) of post-impact collapse
of the WTC Towers (WTC 1 and 2) and WTC 7; expanded its research in areas
of high-priority need such as prevention of progressive collapse, fire
resistance design and retrofit of structures, and fire resistive coatings
for structural steel; and is reaching out to the building and fire safety
communities to pave the way for timely, expedited considerations of recommendations
stemming from the investigation.
