| Description |
In 2005, NIST completed a three-year building and fire safety investigation of the probable causes for the post-impact collapse of World Trade Center Towers 1 and 2 following the terrorist attacks of Sept. 11. As part of the investigation, NIST structural experts examined about 250 pieces of steel recovered from the site. Here NIST researchers Stephen Banovic (left) and Frank Davis take inventory.
