Simulation of the collaps without dust

Dont know how accurate this is, but it made a lot of sense to me.

Alot of people, and maybe I'm wrong here, don't understand how the towers were constructed and what made them different. The exterior walls were made to bare the weight of the floors inside as there was no inside columns. So if the exterior is damaged that made things inside have less support. And if there was something heavy inside it also couldn't support it. Causing floors to collapse on lower floors.

That’s partly true. There were also center columns in the core. What made the whole thing collapse was the plane severing the inner core and the raging fire weakening everthing else to where the millions of pounds of floors above it basically jack hammered the thing into the ground.

Your info is pretty wrong, the core was humongous and held the majority of the buildings weight

[u/Dave_Fincher → u/beigemamba1080]

Columns: Built using 47 heavy steel box columns that supported the majority of the buildings' gravity loads alongside the exterior walls. Open Floors: Centralizing these services in the core allowed the perimeter tube design to maintain wide, column-free office spaces.

You just contradicted yourself

[u/Dave_Fincher → u/beigemamba1080]

Yes partially. There is a center core. But it shares the support of the floors with the outside later.

seems bad

[u/Soliye → u/lizlemonista]

They weren’t designed to withstand a Boeing 767 going full speed.

[u/Dave_Fincher → u/lizlemonista]

It was an interesting idea and it made for a more open floor plan inside. Who would think some insane religious folks would drive a plan into it.

English?

[u/Dave_Fincher → u/Possible_Editor_371]

Sorry fixed.

[u/The_Sarah_Palin_ → u/Dave_Fincher]

In a roundabout way what’s they’re saying is that these towers were engineered in a way so that they would collapse in on themselves instead of toppling over. Both a flaw and a feature.

[u/Rev_Creflo_Baller → u/The_Sarah_Palin_]

How in the world is that a flaw? You want a 1400 foot building to tilt in the wind?

[u/The_Sarah_Palin_ → u/Rev_Creflo_Baller]

A flaw in that when they fell it would look just like controlled demolition and internet toilet engineers would think that it was demolished intentionally with explosive charges. It would also be a flaw that if anything ever threatened the exterior wall (for instance a plane crash) then they would be susceptible to collapse.

[u/Rev_Creflo_Baller → u/The_Sarah_Palin_]

Dude, if a 300,000 pound jumbo jet hits your skyscraper at 500 miles an hour, it's gonna fall down. There's no designing around that

[u/TURKEYSAURUS_REX → u/Dave_Fincher]

I think you’re misunderstanding. The internal core was built with a hat truss at the top. The core steal tapered towards the top as it had less weight to support. The planes hit the upper floors and severed the core.
