[@dylbie]

Incredible work! The 'Component Tests' part is absolutely amazing. I can see you were having the same issues that I encountered whereby the initial shock of the collapse makes the tower fail at the base. Incredibly difficult to solve but it looks like you've sorted it. This has to be one of the most complex simulations ever done. You should win some kind of prize for this project.

[@brymstar333]

Neither tower failed at their base... Collapse for both began in the vicinity of where the planes impacted, the floors above remained intact on their way down until they hit the pile... The floors beneath gave way in sequence, every third floor completely detached, the two above bend and snap, all the way down.... What most people don't know, because they simply don't care to research the matter, is that from the top to the base, every 22 floors the gauge of steel used for the support columns doubled in thickness, to where the columns of the first 22 floors, were massive, and totally overbuilt...rated to support 3 times the maximum occupancy weight of each tower... At some point, all of you have to come to terms with the forensically verified FACT that explosives are what brought those towers down ...

[@sgthartford6347]

​@@brymstar333yep. There's absolutely no way they would have collapsed that quick straight through the path of greatest resistance that was unaffected by damage or fire pulverizing everything in its path below the destruction zone before the collapse made it there. Oh, and they fail to research or recognize several impossible pieces of evidence unless you consider demolition. Like unreacted thermite, iron microspheres melted beams, melted concrete, and the molten steel that stayed molten for several weeks after 9/11. Or the fact that to date no skyscraper has collapsed due to fire.

[@james_fisch]

@@brymstar333 "forensically verified FACT" ahahaha oh god that's a good one. right... You've never watched a controlled demolition in person. The explosions used in those are far louder than the collapses you see in the 9/11 footage. goofy twoofers at it again

[@lugiamastero13]

Amazing this video shows a lot of details i have figured out about the collapses over the years. I noticed that the floors fell first the exterior peeled away and then the core remained for a few moments before the bottom cracked and crumbled. One thing i always remembered about the south towers collapse is when the top section of the building that thing dissappears behind the dust then a fat chunk of the exterior pops out mostly intact from what once attatched to the top block near the roof

[@james_fisch]

That's precisely what I think of when looking at simulations of the collapses with a careful eye due to my morbid fascination with its mechanism. The south tower's collapse is interesting watching so many floors tilt, disappear into a cloud of dust, with what I assumed was the top floors exterior columns breaking apart from the roof and hat truss when coming out of the cloud. I've tried figuring out in my head how those pulled apart like that for years, and it wasn't until the final bit in this video where it really began to make sense. I think Kostack has said before that after they've finished simulations of the Twin Towers, WTC7 would be coming up. I'm really interested in seeing how that turns out as it seems for a lot of people, visualizing how the collapse happened internally prior to its shell collapsing is difficult when the smoke obscured the south face of the building.

[@teeteejones7983]

you'll never figure it out using words like "collapse" it literally turned to dust. it disintegrated in mid-air. most people would view something like this to be impossible. that's why nobody talks about it. you can watch the steel columns turn to dust and blow away like sand in your hand. if you're not familiar with physics you would never suspect it. everything about that day goes against the laws of physics. look up John hutchinson and the Hutchinson effect using frequencies around an electromagnetic field can cause all types of kookie things to happen, chemical bonding, levitation of objects, turning steel to jelly etc also dr judy wood she will allow you to see things like you never thought possible

[@teeteejones7983]

@@lugiamastero13 stop saying collapse. it did not collapse there wasn't 220 stories worth of rubble. it turns to dust in Mid air, nothing about it is typical. there was an ambulance parked right outside the tower it would have been smashed if everything fell on it but it was not it was just covered in dust famous picture. do you think fire in the building would maybe burn the paper? why do you think it didn't?

[@RagingKoala]

I love how the sliced segment at 6:16 of the South Tower-even though it’s still not quite as accurate as it should be-is still very close to how the collapse actually progressed. Especially with the core still remaining after the initial collapse as it did remain in both towers for a few seconds afterwards. Can’t wait to see the final results!

[@EricMalette]

Yeah, there's even a flattened pancake at the pile base that shows how the survivors of stairwell B made it.

[@7249xxl]

did you take into account the different strength levels the towers had? They are comprised of 3 components each varying in column thickness and truss complexity. This is why each part was labeled because the upper most outer sections were 1 think 2/3rds thinner then the parts in the base. This could solve your shock propagation issue as the base

[@lajoswinkler]

You are on a good lead, but things were more complex. Each of the three sections also had tapering of column box walls throughout their heights AND throughout the perimeter at each floor. But yes, shock propagation seen in the simulation seems to originate in columns being simple rods of identical properties when they're supposed to be difficult to squish/bend boxes.

[@calvinrivera49]

less steel thickness for the perimeter, there's a schematic of thru which floors and what thickness in inches or cm. don't recall.

[@7249xxl]

@@calvinrivera49 from fema: For example, the spandrel plates used in the column- to-column connections in the perimeters of WTC 1 and WTC 2 reportedly ranged in thickness from about 1-1/2 inches at the lower levels to as little as 3/8 inch at the upper levels Theres allot of data about this but uts common practice in skyscrapers. Bottom thick bc of the weight mid and top thinner to adjust for said pressure. We just built box pyramids

[@IanZeAlien]

I remember seeing the 1.0 version of the WTC collapse simulation videos from years ago. I'm so glad this popped up randomly for me. Been wanting to see a very detailed simulation of the collapses, as well as the neighboring damage, to see how it "looked like" under the smoke and fire.

[@lajoswinkler]

It is possible you are seeing structural failures way down the model because your basic column elements are just rods which makes the whole model so tight. Columns of these towers were, unlike what lying nutters preach, not solid steel, but _steel boxes with walls that tapered towards the top_ , being few millimetres thick at upper floors. Also, thickness of outer column walls varied across each floor. It was quite an elaborate system designed to maximize lateral load capabilities. You can find these blueprints in the final investigation done by NIST. This arrangement played a huge role in the behaviour during the collapse and it's why the lower parts remained connected while the tops were crushing their way down. Growing pile of falling mass against growing resistance. All in all, you're making better and better simulations each year. Keep up the good work. As models are improved, as computing power available to individuals gets higher, so will this model approach the observed reality of that terrible day.

[@WasFakestCenturyAesthetics]

lol it's "nutty" to think that these total, rapid, vertical skyscraper failures had something in common with 99.9% of other total, rapid, vertical skyscraper failures in history...but totally not nutty to come up with a brand new unprecedented skyscraper collapse phenomenon with no reference to any physical evidence or physical experiment solely in order to conform to your desired conclusion.

Thank you very much and thank you for the offer of help! I think I have most of the documents that have ever been publicly available. Here is what springs to mind: I was particularly missing high-resolution drawings of the underground levels with the PATH terminal, I only have low-resolution files "SKA10-84" ff. There is a "Masterplan" named pack in good resolution, but that is from 1963 and the terminal was still missing from it. I am also missing complete drawings of buildings 3 to 6, including sections. I only have the early draft from 1963 with all the buildings, which probably also changed after that. These drawings may already be somewhere in my archive, but that is really a lot of files. If they have ever been published, then perhaps a keyword that I could search for would help me. What would be particularly helpful is if any drawings were available as vectors, Autocad, DWG, DXF, etc. Almost all the plans I have are bitmaps. Source data is always the most accurate and then the resolution doesn't matter. But don't feel pressured to get all of this now. This project is about showing how the collapse behaves in principle, we don't need every detail for that.

[@BillyO8834]

If i remember correctly, wasn't a lot of the structural support on the outside? 50% of it was compromised by the plane strike. I'm sure the wind at that height also acted like a bellows and increased the temperature of the fire

[@Smedley1947]

@BillyO8834 I have always thought of the World Trade Center buildings in their post impact condition as being similar to a huge hibachi with air vents all the way around the circumference of the building because of the windows being blown out in the crash area. You have all of the flammable debris, the kerosene hundreds of tons of paper from all the filing cabinets in office furniture and tables and ceiling panels Etc in a huge tangled but open mess plus the floors likely having impact holes blown which would facilitate air getting to the many fires. With the windows blown out between the outer columns in the area of the damaged floors, the induced draft of the hot fire would suck outside fresh oxygen-laden air up through the flaming debris through the many holes punched through the floors by the 767. I believe that due to that phenomenon, it would be possible for much hotter fires to occur than if the fires were oxygen starved. And that of course could contribute to the speeding up of the collapse due to the steel floor trusses being greatly weakened by a hotter fire.

[@robertdallara4981]

Definitely seeing the banana peeling / wedge-in effect of the top section in that last simulation there, just like in the real collapse videos! Might be good to "color code" the columns of the top vs bottom section so we can more easily discern the behavior of both the perimeter and core columns during the collapse. It would also tell us how intact the top section remains throughout the whole collapse. It will be very interesting to see what the final simulation will show happening to the core columns of both the top and bottom sections...

In all these simulations, there is one common theme: The bottom of the towers collapsed/failed prior to the top failing. Unfortunately there is no video evidence to back up this series of events. In every video, the top collapses and causes both towers to fall at free fall speed through the path of most resistance. Don't forget, the bottom 80 floors were completely undamaged. And in these simulations of the collapses, it shows something that did not happen: The bottom of the towers collapsing before the top of the towers.

@@muzzmacc6411 I believe NIST explains it as once the first floor collapsed the rest were destined to collapse. Each floor was designed to only hold its own floors weight. That's my laymans way of explaining NIST's complicated way...Lol

Cada vez se confirma más que fue caída por los aviones y no por bombitas escondidas

[@lajoswinkler]

It was confirmed *back in 2005* that it was because of the combination of widespread structural damage and fire that was immediately ignited on so many floors. Neither of the events were included in the design. Their combination... absolutely outside of any design. There really isn't anything suspicious with this. Primary report by FEMA was badly done, but NIST's was totally fine. It's the relentless work of the conspiracy idiots that has sadly pushed the absurd narrative of "planted bombs" into the accepted mainstream. Just pure human idiocy. While we could discuss about political ramifications of this tragedy and possibly willful ignoring of signs by the state agencies, the physics alone is untainted. There is literally nothing suspicious about what happened that day.

Incredible how they both fell at near free fall speeds! As if the supporting trusses and girders gave way without any resistance!

Did they? How near is "near" anyway? How "near" does it need to be to rank as "incredible"? What is "free fall SPEEDS" since free fall is not a measurement of velocity? When a structure fails (for any reason) doesn't that automatically mean resistance is removed?

[@jmoy4408]

Great!

[@sebastianhaugland5611]

I dont think this is the way they collapsed. From documentaries, they showed how the outer walls leaned inward, due to sagging of the floors. Evetntually leading to a collapse at the damaged areas. Pancaking downward. This video shos immediate coolapse at the bottom, and outer suppørt collums falling first. In vidoes of the collapse, you can see the smcenter collums collapse almost at the same time, but somewhat delayed. You do great work on the simualtion, and i get its really hard to recreate the exact conditions. 😊

[@MFitz12]

It isn't. Says so right in the Title and in the Description.

It's not up to you to decide what is part of the topic and what is not. Have I made myself clear? If you want to find out what happened underground there are plenty of photos, video and a few books that describe it in detail. 60 Minutes did a whole hour on it.

By sharing these failed attempts and prototype simulations, my goal is to illustrate the challenges and learning experiences that were crucial for refining the model of the WTC collapse over time. This video offers a glimpse into the development journey, emphasizing the importance of experimentation and analysis in achieving more accurate results.
