A week after the collapse of Champlain Towers South I released this quick response video. With the preliminary information at hand immediately after the tragedy it illustrates the collapse sequence and a potential explanation of the failure. For the more complete explanation with additional evidence see the part 2 and 3 videos.
On 24 Jun 2021 the Champlain South Tower collapsed at 1:15am. This was a 13 story condominium building in Miami Florida in the town of Surfside. It was built in 1981.
The 3D animation is made from Architectural and Structural drawings made available by the town of Surfside. The events and sequences are based on key photographic evidence and eyewitness accounts.
I am an Architect with a career in designing and constructing buildings including experience in the USA. I caution that its still too early to know why it collapsed. This video is only a possible explanation of this failure.

You should take that as a lesson when it comes to everything concerning the news, the days of reporters and news teams getting their facts straight before reporting on something are over, especially concerning politics, they're even worse in that area because they're flagrantly biased when it comes to that, every media outlet has it's political agenda in this day and age and that is what's turned them into advocates instead of reporters like they were years ago.

Your simulation shows a key issue about the building’s original construction, however doesn’t focus on the columns!! The columns under the portion of the tower that first fell and the pool deck look to be close to half the size and strength of the columns under the part of the building that survived the initial collapse.

Your remark supposes that there is a single answer why this collapse happened.and that an engineer ought to be able to figure it out just by looking at the pictures. In fact there are multiple possibilities and it would be irresponsible to issue a verdict without careful examination of all the evidence, much of which cannot be determined by observation, such as the type and strength of the concrete used.

What a tragedy. As a board member of our 530-unit condo complex in Culver City, California, we do a complete inspections of our property every two years (15 buildings). About 5 years ago we discovered considerable spalling in a few of our buildings (underground carports). We got bids right away and fixed the problems, paid out of our reserves. Two years ago, we discovered spalling in the basement underneath our clubhouse...one of our pools is right next to it. It took some time to discover that our pool was leaking. We are currently wrapping up an extensive project to fix this problem. I am grateful to have worked on a board and with our HOA manager to address problems as they arise. Our monthly dues are $504 per month...very high...but we have money available to fix these types of problems when they arise.

@@Mike-Bell I was kind of wondering if it might not be some kind of punching shear failure when they said the building had been settling over the years. If some parts of the building settle more than others, that would increase the axial load (and therefore also the punching shear) on the columns which have settled less. Then I read that there had been problems with rebar corrosion, and that the collapse seemed to happen in the pool area first. I'd been struggling to figure out how an initial collapse in the pool area (outside the building footprint) could cause the whole building to come down. When I saw your animation, and the actual photos of the columns punched through the slab, I thought 'ah, that makes sense'. I hope all is well your side, and that your mom is doing well.

@@garymostert4811 If you look closely at pics of the rebar of the punch shear columns it has been commented how woefully little steel is visible. this comment on reddit is pertient... I design these kinds of buildings for a living. This building would not meet modern codes, and just simply wouldn't be built this way today. The columns are extremely small ( And packed with steel, 8 #11 on a 16X16 column is absurd), the slabs are fairly thin for a conventional reinforced slab. I imagine the slabs were designed to razor thin margins even by that times codes. I don't think there was any shear reinforcement at the slab column joint either, which makes a punching shear failure more catastrophic. If built by modern standards the building would have surely had more shear walls on the south end. These would have helped stabilize the building laterally and helped keep the south portion from collapsing long enough for evacuation to occur. www.reddit.com/r/CatastrophicFailure/comments/ocv4rv/simulation_of_surfside_condo_collapse_catenary/

@@Mike-Bell Sorry to step in while the experts are doing such a good job, but two things I'd like to comment on (and I'm no expert). First, my first thought on seeing the pictures the day of the collapse was that compared to other building destroying disasters (earthquakes come to mind), these pictures seem to show a woefully inadequate amount of steel within the concrete. Second, I too wondered how a pool "outside the building footprint" could bring this tower down -- my current way of thinking of it (with the help of your video) is that it's only "outside the building footprint" until you look at it from the perspective of the parking structure. Then it's all within the footprint (reminds me a little of Wacker Drive in Chicago in that regards).

Wasn't stupidity but grace. She was a devotee of Our Lady of Guadelupe and our Lady interceded to the Lord for her benefit. Part of this involved blinding her to the fact that there were stairs literally 2 doors down, yet she knew about the ones at the other end of the building. Just one moment seeing a person go in or out that stair door, during the 10 months she'd live there, she would have know they were there, taken them, and been killed. And no human would have foreknown for those 10 months, that it would be the other section of the building to survive. If you read the story with a sympathetic eye - or even a mildly skeptical one - and think about it - it's clearly miraculous. So here is the advice, Grace is better to have than intelligence or stupidity. Or be a sukka and think it was somehow all luck. Pretty strong message there.

Since we had a big earthquake followed by other 4000 ones here in my city, in Albania from 2019 - 2020, buildings collapsed and almost every house or building were damaged, I've read and followed many documentaries about building failure to prepere for the next one or any possible building failure. We have similar ground to Miami, a swampy one near the sea. By what i learned so far, in big structures like this, if no earthquake is involved, it doesn't happen out of the blue. There must have been cracks in the columns or walls, the ground level, down in the garage. People need to pay attention to their buildings, especially near the sea where's underground erosion.

Generally that one deck slab you are referring to that divides the sub to the super structure is appointed as a transfer plate. The layout of the carpark and the dwellings above are considerably different. That being said transfer plates can take many form at many levels pending the design of the structure as a whole. If the video is correct in its theory of punching, then id say the design or construction or both were inefficient. Could have been below the basement as well, ie the footing systems causing settlement differentially loading other areas past their limits. I doubt the loading of the building was in excess although it could have contributed to the above factors. There may also have been load additions to the building that may not have been factored well. The structural engineers/ builder and owner of the building will have some idea of the reasons, 100%.
@albud6687

2 major design mistakes. (1) hooking the deck to the middle of columns, not continuous with a slab on the other side, guarantees this situation buckles them. (2) Having the exterior, optional, feature-recreational surface slab - its concrete exposed to the elements fully even more than the roof - poured and rebar'd into the main tower columns. A fix would require separate abutting columns or a plate/sill on the main columns (making them double wide). Expect new codes to mitigate these issues. (1) is the most glaringly obvious problem. I might not have caught it but if a senior engineer n the company reviewed the drawings, no way they'd miss that.

This would of prevented the collapse of the building. This clip clearly demonstrates my own thinking of the failure modes, its great really. So there is clearly a design flaw. It goes without saying had the waterproofing been maintained then it would of never happened but really one shouldnt be relying on the upkeep of the waterproofing system.

Great video. My understanding from the Morobito report is that the pool deck was not properly sloped to allow water runoff and standing water collected for long periods around the location of the column punch throughs. Water was also leaking in the same area to the parking deck below.
@Mike-Bell
@Mike-Bell 2 жыл бұрын
Slabs are routinely flat on top because it is much less fuss and quicker. The slope is achieve thru tapered topping. The issue is to not let the topping get too thick which is done with more frequent outlets. The sloped topping is visible is visible in fotos of the failed pool deck and the topping is pretty thick in parts. Morabito has created a misconception with this statement. There were extensive stalactites of the garage ceiling but this was due to non maintained and failed waterproofing. Not because the deck was flat.

Seen a lot of theories, but this makes a lot of sense. That pool deck was obviously severly compromised. I imagine future builds wont make a building so precariously susceptible to a domino effect like the one that happened here. Another person noticed that the support columns on the collapsed portion of the building were smaller than the support columns on the part of the building left standing. This just seems like an architectural failure on many levels.

Newer buildings have already been built stronger than this. At the time though this style was common in multiple cities across the United States. Although that doesn't mean other buildings of this style are going to collapse because it all depends on environmental elements. Climate change will cause much more damage to cities on the coast especially those in Florida, Louisiana, and Texas due to the effects of hurricanes and the rising water. Already there are multiple areas of Miami where sea water comes up from the ground. You'd think it had just rained and move along until you get told it didn't rain at all and the water is standing.

Earth has changed so much over so long, no matter what humans have done. Trying to stop the earth from going through it's changes is kind of futile. Whether we survive as a species is the real question. Yes, there are things that can be done to help along the way, but in the end, mother nature is going to do what she wants and is going to go through changes that she's been going through since the beginning of time. I'd rather just try to keep trash out the ocean and see nature parks in California properly take care of their foliage to prevent wild fires. By that, I mean they need to do seasonal controlled burns so that all of that natural fuel can be removed for new growth to begin. Thus preventing more fires. There are so many simple things we can do, that people just don't realize, because they see fire, and instantly think bad. They've done it for years in many national parks. Controlled fires prevent uncontrollable ones. Anyways, we really have built a lot of things on the coasts that should have never been built, because eventually water levels were gonna rise and destruction was basically eminent. Humans really do think we can build anywhere we want without consequences. Pompeii for example.

There were massive dirt filled planter boxes next to those columns on the pool deck.

One of the things that they could’ve done to prevent a complete and total collapse is to do the same thing that they do on modern bridges. On modern bridges they design the bridge with uneven spacing between the sections and columns to get them not to tug on each other during failures. If you look at bridges the center spans are farther apart than the ones closer to the shore. Engineers have found out the hard way to do that to bridges. It looks like some building engineers are going to have to find out the hard way that they need to follow suit too.

It sounds like there were various things going on, think we'll have to wait on a more expansive report. Some say the design of the drainage was poor, it was a level surface rather than graded which would naturally cause any sort of water buildup to flow away, potentially made an ideal circumstance to rust or decay the material around it, or just increasing pore fluid pressure which makes shear stress failure more likely too. But this is all speculation as we don't quite know what point or points of failure caused this. Could even be a little bit of everything.

I'm not ignorant of the tragedy of the situation. But I don't see any good reason to immerse myself in it. We can't help anybody who died, but we can learn how this happened and that knowledge will help us understand how to better protect against things like this in the future.

Great video Mike! Your sequence of events makes total sense with the witness accounts, engineering report, and the post collapse evidence of column punch through. The pool was supported by horizontal transfer girders that were supported by columns. My sequence of events matches yours except for the horizontal transfer girders. I believe that the transfer girders failed first thus causing the column punch through. The waterproofing failed over time and the girders were exposed to constant salt water destroying their integrity, and they also renovated the pool adding substantial weight for them to support. You don’t state in your video what you believe caused the punch through so we could be on the same page? A tragic event!

Very few people had heard of the city of Surfside outside of Dade County and Surfside Mayor Burkett was certainly unknown to the world. When he turned in for the night at 11 p.m. he had no clue that he would be addressing the world media in less than 24 hours for a catastrophe in the city. Just like the city of Parkland (school shooting) in Broward. Small unheard of city suddenly known across the world.

This makes sense. I've done Civil and architecture construction, building bridges, interstate ramps and beach house 15 story buildings. I'm surprised in what little work went into the base of the building. We would drive several pilings into the ground and cap them off with a ton of concrete and rebar. Then build thick steel up too every floor and that would be boxed in with more rebar and concrete.

Excellent FMCA analysis. So basically the structure failed like a soda can dented on the side. They should have had built in shear failure points on the pool deck so as not to allow the huge lever arm to bend the columns under compression after punch through. Sad part is they knew this failure mode report done by some local Professor.

Just as many other similar older multi-story condos in other areas of FL are now "all of a sudden" being declared "unsafe". These are multi-story homes, owned by the residents, and should be paid for by the owners who neglected them....just as my house would be if I let it deteriorate to the extent the roof collapsed.
