Task force to probe collapse of WTC
01 October 2001
The American Institute of Steel Construction Inc (AISC) has formed a special task force to investigate the structural collapses of the World Trade Center buildings in New York following the terrorist attacks there.
AISC is the technical institute responsible for developing and maintaining standards for design and construction of steel buildings in the US. Information developed by this task force will enable AISC to determine if modifications are needed to existing standards.
"AISC strives to create a steel building specification that makes use of the latest available design data and construction technology," said Nestor R Iwankiw, AISC's vice president of engineering and research.
"The special task force of nationally recognised experts will investigate and determine the various factors that contributed to the collapses and make recommendations to AISC's specification, blast and fire committees."
Most engineers currently believe the collapses occurred as a result of a combination of extraordinary events, including the initial aircraft impacts and explosions, which destroyed part of the structure, and the subsequent extreme fire, which progressively weakened the remaining structure.
