Abstract

In March 2002 NIST became the lead agency in an investigation of the World Trade Center collapse. The investigation addresses many aspects of the catastrophe, from occupant egress to factors affecting how long the Twin Towers stood after being hit by the airplanes, with the goal of gaining valuable information for the future. A critical aspect of the investigation, conducted by MSEL, is the metallurgical analysis of structural steel from the Twin Towers and WTC 7. The analysis includes characterization of properties, failure modes, and temperature excursions seen by the steel.
