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 is conducting
a three-part plan: a 24-month 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; a research
and development program to provide the technical basis for improved
building and fire codes, standards, and practices; and a dissemination
and technical assistance program to engage leaders of the construction
and building community in implementing proposed changes to practices,
standards and codes. Also it will provide practical guidance and tools
to better prepare facility owners, contractors, architects, engineers,
emergency responders, and regulatory authorities to respond to future
disasters.
This dedicated Web
site will be updated regularly to keep the public, the news media, and
all other interested parties current on NIST's efforts to carry out the
WTC response plan.
