There are many contributing factors to the fall of the World Trade Center. The World Trade Center was the first super-tall building to be built without masonry. The support beams were composed of small steel bars, forming hollow tubes to support the massive weight of the tower. Another reason is simply the nature of the impact on the towers. The World Trade Center was the first super-tall building to be built without masonry. Due to the high air pressure created by the elevators, engineers were worried that conventional shafts would fail. So engineers developed a new system to deal with the problem.

Another contributing factor to the collapse of the World Trade Center is the fact that the support beams used were not made of solid metal.
