Why Did the World Trade Center Buildings Collapse?
On September 11, 2001, the world was changed forever when two planes crashed into the World Trade Center Towers in New York City. This tragic event left many people asking why did the buildings collapse? The answer lies in a combination of factors, including the impact of the planes, the design of the buildings, and the fire that ensued.
The design of the buildings was a major factor in their collapse, as the towers were built with lightweight aluminum and steel frames. This design allowed the towers to be built at over 1,300 feet, weighing hundreds of thousands of tons. The weight of the building and the fact that it was made with lightweight materials meant that it was not designed to withstand the impact of an airplane.
The force of the plane crashes was another factor in the towers’ collapse. The two planes that crashed into the buildings were traveling at speeds of over 500 miles per hour, and the force of the impact was strong enough to damage the buildings’ structural integrity. The outer steel and aluminum frames were bent and weakened, and the inner core of the buildings was heavily damaged.
The fire that ensued after the plane crashes also played a role in weakening the buildings’ structures. The
