How Did the Wtc Collapse?

The collapse of the world trade center occurred during the terrorist attacks of september 11, 2001, after the twin towers were struck by two hijacked commercial airliners. One world trade center (wtc 1, or the north tower) was hit at 8:46 a.m. Eastern time and collapsed at 10:28 a.m.

How Did the Wtc Collapse?

The collapse of the World Trade Center (WTC) on September 11, 2001 was one of the most catastrophic events in modern history. Although the specific cause of the collapse of the twin towers has been debated extensively, the general consensus is that the combination of the intense heat from the jet fuel-fed fires and the damage caused by the impact of the two hijacked planes caused the steel support structures of the buildings to fail.

The towers were designed with a “tube-in-tube” system, with closely spaced steel columns forming a hollow core, surrounded by thick walls of steel, concrete, and other materials. This design was meant to be fireproof and gave the buildings their incredible strength. The intense heat of the jet fuel fires, however, weakened the steel columns and caused them to buckle.

The impact of the planes also caused extensive damage to the structures of the towers. The force of the collisions caused the building’s facades to crumble, as well as damaging the outer columns and internal walls of the building. The impact of the planes also damaged the fireproofing material that was meant to protect the steel columns from the intense heat of the jet fuel-fed fires.
