Summary

The 9/11 attacks on the World Trade Center caused massive structural damage and fires, leading to the collapse of both 110-story towers, resulting in 2,830 deaths. A study by FEMA and ASCE found that the damage was not initially catastrophic, but the subsequent fires weakened the steel structures, causing collapse. The towers' design and construction features, such as robust steel framing and adequate egress stairways, allowed them to stand for a time and enabled many occupants to evacuate. The study identified key factors contributing to the collapse, including the spread of fires and the weakening of structural elements, but did not find any substandard structural features.
