It is understood the South Tower collapsed sooner because it suffered more damage from the initial aircraft impact, which also dislodged more fireproofing material. While there are different theories regarding how the progressive collapse of Building 7 was initiated, there is consensus among investigators fire was the primary cause of failure.
Both official reports made a range of fire safety recommendations for other high-rise buildings, including to improve evacuation and emergency response. In , the National Institute of Standards and Technology also published a best practice guide recommending solutions to reduce risk of progressive collapse. There have since been changes to building codes and standards on improving the structural performance of buildings on fire, as well as opportunities to escape such as added stairwell requirements.
At the same time, the collapse of the twin towers demonstrated the very real dangers of fire in high-rise buildings. In the decades since the World Trade Center was designed, buildings have become taller and more complex, as societies demand sustainable and cost-effective housing in large cities. This can be partly attributed to the wide use of flammable cladding.
It is marketed as an innovative, cost-effective and sustainable material, yet it has shown significant shortcomings in terms of fire safety — as witnessed in the Grenfell Disaster.
The Grenfell fire and similar cladding fires are proof that fire safety in tall buildings is still a problem. And as structures get taller and more complex, with new and innovative designs and materials, questions around fire safety will only become more difficult to answer.
Did you know Edit. Connections Featured in Mysteries Part 1: Demolitions User reviews 3 Review. Top review. So many similarities to the fictional "Towering Inferno". Fascinating and eerie. Essentially , a prime example of all that can go wrong at once. All the elevators and sprinklers were in the center of each floor. A weak and unstable distribution of the weight of each floor by a precarious cantilever design using far too small girders, joints, and bolt-connectors.
No cinder block to speak of or not used at all. Wallboard was used instead. About all that didn't happen is that electrical wiring didn't catch fire, like in "Inferno". I suspect that, in reality, a similar pancaking effect might have happened in the fictitious story of "The Towering Inferno". Again, the "specs" were not tough enough for a story building, while it did meet building codes designed for much smaller buildings.
The architect of the building looks totally "spooked" and guilty about the whole thing. All in the name of more "retail floor space" than the solidly built Empire State Building. Beautifully produced by the BBC and not at all dry or boring to me. Tastefully produced with a minimum of explicit scenes. When you find out why the "Twin Towers" were selected as targets, you will be very surprised!
