University Study Finds Fire Did Not Cause Building 7’s Collapse on 9/11

A Structural Reevaluation of the Collapse of World Trade Center 7

March 2020

U of Alaska, Fairbanks

On March 25, 2020, researchers at the University of Alaska Fairbanks issued the final report of a four-year computer modeling study on the collapse of World Trade Center Building 7.

The 47-story WTC 7 was the third skyscraper to be completely destroyed on September 11, 2001, collapsing rapidly and symmetrically into its footprint at 5:20 PM. Seven years later, investigators at the National Institute of Standards and Technology (NIST) concluded that WTC 7 was the first steel-framed high-rise ever to have collapsed solely as a result of normal office fires.

Contrary to the conclusions of NIST, the UAF research team finds that the collapse of WTC 7 on 9/11 was not caused by fires but instead was caused by the near-simultaneous failure of every column in the building.
