What's inside One World Trade Center's structure?

In this video, I used 3D animation to show what's inside one World Trade Center building of the United States. I will work to make more videos in the future in my free time. I hope you support my content.

Yeah, you can see their primary goal with this new tower was to make the stairways protected and separated from one another to maximize the likelihood you can take the stairs to get out, even if a commercial jet flies into it.

[@probochronicles3991]

I like that they made a special staircases for first responders to use in an emergency.

[@BlackChad792]

Is it just me or does anyone else think those staircases are still to close together...? Like if a big ass plane like the one from 9/11 would smash through the floor it looks like it would destroy or at least damage both of them.

[@adamk203]

@@BlackChad792 A concrete core that thick would be effectively impenetrable to aircraft. High strength concrete combined with heavy reinforcement would shield most of the core from any impact damage.

[@doodledangernoodle2517]

The biggest point against 1WTC is not making the roof height 1,776 feet then having the antenna bring it up to 1,973 feet which is the year the Twin Towers were completed. Having the antenna count toward the full height is such a cop out. The Antenna isn’t even covered in the planned spire to make it look less naked. Since we aren’t getting Twins again, we should’ve at least made 1WTC bigger by roof height than the Twin Towers.

[@scratchpad7954]

In a big way, I agree with that sentiment. They could have made the roof height 1,776 feet and used a 225-foot antenna spire to raise the total height to 2,001 feet to symbolize the year the old towers fell, but I feel that would be very insensitive to the families who lost loved ones and friends that day. But I agree that counting the spire toward the total height of a building is cheating as opposed to counting to the roof or the highest occupied floor.

[@mikefialko2979]

I agree. To say a building is 1,776 feet tall when almost the top 400 feet are an antenna is not accurate. The height of a building should be measured from the ground level to the top of the roof.Antenna and spires should not count.

[@wll1500]

Agreed, but there's no market for office space anymore. They struggle to find tenants, which is why WTC 2 hasn't been started and may never be. I think they only made One WTC as big as they did for symbolic purposes. A smaller building would have actually been more practical.

[@scratchpad7954]

Wow, this is a very interesting video. I love the structure design of the World Trade Center, especially as it fixes lots of the mistakes pre-9/11.

[@uzaiyaro]

Personally, I think it’s difficult to consider the past towers a mistake in some way. Aircraft the size of a 757/767 simply did not exist back when these things were built, and even if they did, the concrete technology to make cores as strong as they are now, similarly didn’t exist. Even putting that to the side, a terrorist attack really wasn’t something designed for; 9/11 was quite unprecedented. The pre-9/11 world and post 9/11 world, for better or worse, is a vastly different place. The unprecedented nature of these attacks is specifically why the legacy of said attacks is so far-reaching into our everyday lives. The TSA, for example, came into being specifically as a 9/11 security shakeup.

[@franksfuterisonlyinches6405]

Most mistakes, engineering wise, are always figured out after a tragedy.

[@cliftwingclifton1401]

Yeah pretty unpredictable that a big ass plane would crash into it…

[@TheTotallyRealXiJinping]

Calling the design of the TT a ‘mistake’ is wishful thinking. The architect didn’t get a full evacuation plan in case of 400 mph plane strike, because it hasn’t happened yet. The word you’re looking for is ‘faults’

[@ANTUBER]

You guys realize 9/11 wasn't the only attack on the Twin Towers....? Sure they didn't expect a big plane to hit the tower, but they did expect some sort of terrorism to do with the towers. It was literally the most famous towers in the world.

[@nahblue]

You can see some of the features of "learning" from the old WTC design. There seems to be three stairwells instead of two, and two of them are further separated so that it increases the chance that one of them is usable and they don't both get blocked. See timestamp 2:19

[@ShadowLinkxMaster]

There were three stairwells in the original buildings as well.

[@azul8811]

In extinguishing fires In high rise buildings the FDNY stretches their hose lines off an outlet of the standpipe riser which is located in the enclosed stairwell of the floor below the fire floor. This necessitates that the door to the stairwell be kept open. Unfortunately, it also causes the entire stairwell above the fire floor to fill with heat and smoke. As a matter of procedure, they designate this as the attack stairway and the other stairway as the evacuation stairway. However, building occupants may ignore such direction. By having a dedicated stairway, the possibility of such a situation might be greatly reduced.

[@uzaiyaro]

@@azul8811 ahh so it’s an exit with a dry riser in it? I dunno why I didn’t think of that, but that makes sense. But also makes sense as an attack point. I’ve seen dry risers inside cupboards as well. I used to do telecom installs in a former life (which is why I forgot), and sometimes the cable or power distribution cavities would be next to a dry riser cupboard, and of course, these are part of the building core, with the lift shafts and exits next door.

[@azul8811]

@@uzaiyaro Actually, I’d imagine that it’s not dry. New standpipe systems are typically “combination systems” in that they are tied in with the sprinkler system. IDK why they would necessarily be dry because freezing is not an issue inside a structure that is heated. You can tell if it’s a combination system by the yellow color of the Siamese on exterior of the building. Green Siamese for sprinkler, red Siamese for standpipe and yellow for combination. Unlike in some jurisdictions, the NYC Code requires that standpipe outlets are located in the enclosed stair rather than in the public hall. And again the FDNY stretches from the floor below the fire floor.

The passengers on flight 93 were aware of the hi jacked planes hitting WTC. They found out by phone conversation, so they reacted to the news.

Flight 93 was downed by the passengers because they were told about the planes hitting the world trade center when they called their spouses.
