Dominant Factor in the Collapse of WTC-1
Publication: Journal of Performance of Constructed Facilities
Volume 23, Issue 4
Abstract
The behavior of the World Trade Center Tower 1 on September 11, 2001 is studied in light of experimental data on the effect of elevated temperature on mechanical properties of structural steel. It is concluded that the damage inflicted by aircraft impact on the insulation of the core framing was the dominant factor in the collapse of the structure.
