The collapses of the World Trade Center towers on September 11, 2001, resulted from a combination of aircraft impact damage and the ensuing fires. This report documents: The information obtained on the factors that affected the nature, duration and location of the fires and how this was obtained; The development and validation of the fire model used to simulate the fires; Descriptions of the most likely fires, as they were reconstructed; and The modeling and validation of the heat transfer from the fires to the buildings' structural members.
