South Florida Condo Collapse

I think they’re just doing it to mess with you.

You should find a cooler place to hang out with cooler friends that will appreciate your contributions.

Honestly, because I got tired of sifting through nearly 200 more shitposts, so I just split it at where I was trying to talk COVID specifically because of the condo involvement, but you all just lost your fucking minds, at that point.

Ha! I lost my mind decades ago! That’s what you know, ya Texas queer!

Excellent thread title. Kudos sir.

Premises are not facts, they are just propositions that can be true or false.

False propositions can still be used to create valid logic and a conclusion, whether it is true or false, unassailable by simple logical analysis, without additional rules of inference.

E.g. modus ponens, “I can see my shadow (p), therefore the sun is out (q).”

This statement and conclusion are logically valid (p follows q), but unsound and provably false in a number of contexts (e.g. moonlight, spotlight, firelight).

BuT I caNt brEaThe!

Outside, 14 feet away from other people, excepting for runner’s slip stream situations, unnecessary.

Yes. Buy more masks from the country that made you have to wear masks.

We do lockdowns instead.

You should all go to New Zealand and infect those smug bastards.

Like all the Kalifornicators are moving to Idaho…

NZ implements strict immigration rules, LOL. How progressive of them?

An offer was made for up to $120M on the property.

I work in structural design and construction and have followed the Florida collapse case in a forum for structural engineers, so when I saw the title of this thread I thought I may add some comments, but it kinda looks like the discussion here went elsewhere…

New Zealand is the Colonial name, you Imperialist dog.

I’d be interested hear what you have to say.

Come back.

Long time no see.

Well, trying to not be long-winded, the building had a lot of problems stemming from the original construction, when an additional penthouse level was built that was not part of the original structural calculations. Analysis of the way the structure failed at the slabs shows significant spalling, as if the reinforcement had been laid directly over the form-work and not given the minimum cover required, which is a bad practice I see a lot here in the third world. That would make the slabs fail to add diaphragm stiffening to the larger structure. The area that collapsed also had per the original design smaller columns that the other sector of the building and IIRC there were some columns transitioned to support on beams instead of just going all the way up from the foundations.

There had been failure warning signs for a long while already, with columns cracking and exposing corroded reinforcement. There was recurrent water leak at the area of the basement parking adyacent to the adjoined pool deck area which showed that protection had been compromised. Beams in the pool area showed significant outer deterioration. A study was conducted by professional and repair measures were recommended which were not followed beyond some cosmetic coverage with expansive grout.

Examination of recent photographs showed that the adjoined pool deck slab had already begun to fail. This slab was an extension of the building structure, something that is not recommended by good structural practice where you try to isolate different geometric blocks as separate, self-supporting structures. If persistent moisture corroded the reinforcement inside the structure, that may have contributed to a growing weakness that was made worse by the effects of a recent nearby big construction project creating temporary soil movement, by the temporary loads of renovations being done on the roof slab, and by any possible incident like somebody’s car in the basement parking hitting one of the columns.

The way the building failed seemed to be that the lower slab extended to the pool deck failed first, shearing off the support columns. The columns there suddenly lacked lateral restrain and had now twice its actual-working length because of now being 2-story unsupported length, which caused them to fail in flex-compression and made the whole thing collapse.

The collapsed building has a twin project elsewhere in the area that is still standing but shows similar signs of impending structural failure. (No penthouse added level on that one, though). Resident have not accepted to move out, apparently.

There is legislation that buildings need to be recertified as structurally sound every 40 years because of some famous failures there back in the 70s or so, and this building was about to undergo the process of recertification. People are now arguing that this time range has to be less.

Thank you.

Well written and easy for the layman to follow.

You still in South America (if I remember correctly)?

Glad it was not a slog.

I still live in Honduras, Central America.
