This report describes how the fires that followed the impact of debris from the collapse of WTC 1 (the north tower) led to the collapse of WTC 7; an evaluation of the building evacuation and emergency response procedures; what procedures and practices were

Global Structural Analysis of the Response of World Trade Center Building 7 to Fires and Debris Impact Damage, Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-9A)

November 20, 2008
Author(s)
Robert S. MacNeill, Therese P. McAllister
This report analyzes the global response of WTC 7 to fire-induced structural failures and the resulting sequence of component and subsystem failures to determine the events that led to the global collapse of the building. The analysis involved a finite

Structural Fire Response and Probable Collapse Sequence of World Trade Center Building 7, Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-9) VOLUMES 1 and 2
