Program Overview
|
|
|
NOVA takes a look at what can be learned from the World Trade Center
disaster.
The program:
-
reviews the structure of the Alfred A. Murrah building in
Oklahoma City and details how the building suffered a
progressive collapse when bombed in 1995.
-
notes that the American Society of Civil Engineers found that
the World Trade Center (WTC) towers performed well when attacked
and that there was no tradeoff of safety for economy in
construction.
-
reviews findings from the National Institute of Standards and
Technology (NIST) detailing how and why the WTC towers
collapsed.
-
reports on NIST conclusions that the WTC had no structural flaws
that could account for its collapse—the towers fell due to
the interplay between the impact damage and fire.
-
summarizes some of the NIST recommendations for improving safety
standards that resulted from the study of the WTC collapse.
-
specifies safety features being designed into China's World
Financial Center in Shanghai, which will be the world's tallest
building when completed.
-
details the safety features in the newly rebuilt #7 WTC building
(the third skyscraper to collapse).
explores the question of how safe is safe enough?
