The structural steel of the skyscraper, built to withstand winds in excess of 200 miles per hour and a large conventional fire, could not withstand the tremendous heat generated by the burning jet fuel. At 10:30 a.m., the north building of the twin towers collapsed.
How Did the World Trade Center Collapse?
The collapse of the World Trade Center on September 11, 2001, was one of the most devastating events in history. On that day, two hijacked planes crashed into the Twin Towers in New York City, resulting in the collapse of both buildings as well as the death of thousands of people. The tragedy has sparked an ongoing debate as to how exactly the towers were brought down.
The most widely accepted explanation for the collapse of the World Trade Center is that the intense heat from the burning jet fuel weakened the steel columns of the buildings, causing them to buckle and eventually collapse. The impact of the planes caused a chain reaction of fires, which spread rapidly through the buildings. The intense heat from the fires weakened the steel structure of the buildings, causing it to collapse. In addition to the heat, the intense vibration from the impact also contributed to the weakening of the steel structure.
Another theory that has been proposed is that the collapse was caused by the failure of the fireproofing material on the steel columns, which allowed the intense heat to penetrate the steel and cause it to weaken. This theory has been largely debunked, however, as the fireproofing material was designed to withstand temperatures up to 2000 degrees Fahrenheit.
A third theory is that the buildings were
