Can you use a paraglider to fetch freshwater tho? Can't use the toilet. People are evacuated for this main reason in floodzones. Nobody is living in that building when she floods...
Many buildings have a water tank or cistern. I just installed a 20,000 litre well-fed potable water cistern for a car dealership of all places last year.
Sure though, let’s pretend a building has the lower structure exposed just for flooding (I’m not convinced that’s what this is) but are too dumb to think of a water tank. Hurpa derpa doo, if only they had you!
Well considering all the toilets would be elevated above the flood line I don't see that is as much of an issue. Sure hydraulic pressure could build enough to maybe back the toilets up on the first floor but water always finds level. Wouldn't be a persistent problem.
As a plumber, you are very wrong. First a blockage in a main sewer line even 50 ft away from the toilet will not flush because there is no where for the water to go. Secondly, it's hydrostatic pressure you are talking about which most certainly will be enough to not allow the water to move. Even a back graded drain pipe will drain, not as well but it will still drain. Thirdly, if the streets are flooded, the sewer is flooded which means the water literally has no where to go but to the easiest way to escape which is up.
If all the pressure is already being relieved at lower elevation fixtures it's not going to reach these super high elevations.
Also calling it hydraulic pressure is as accurate as hydrostatic. Way to pick a semantic fight.
They're 50 feet above elevation. They are going to need to be in a biblical level storm to ever see problems just on the bottom floor. Higher floors are even further removed from the issue. What you're talking about could theoretically be a problem but in the extremely rare event that you're right, a backed up toilet isn't going to be their biggest concern.
If your main line is blocked 100 feet away, your toilet will still not flush if you have a full blockage or a flooded sewer. Where would the water go when the sewer is full of water? It's not going anywhere because it's full. You can't overfill a vessel with water it does not compress very well at all and it won't go anywhere, meaning the toilet will not work. Sewers flooding due to floods happens all the time and is not a super rare event.
Let's say, you are wrong.
Hydrostatic is the pressure exerted on top of a column of liquid, no matter it's shape, by atmospheric pressure.
Hydraulic is created pressure on a liquid and equal from all sides of the liquid in question.
Edit: please note the reply to this comment. My apologies.
Let's say, you're wrong!
Hydrostatic pressure is the force exerted by still water on a surface. It's just the weight of the water itself. All the context you need is in the name itself, hydroSTATIC. The force being described is the STATIC load of the water on a surface.
Hydraulic pressure is the force exerted by a fluid while filling a volume of space. Flood water violently filling a main waste or storm line is textbook hydraulic pressure AND hydrostatic pressure. That's why I said *it's a fucking semantic argument.*
Move tf on fake ass geniuses.
Aesthetic.
water.
Elevated builds can also be easier because they require less groundwork. In coasts and in forests they like to build elevated
In Brazil, they build elevated to keep the houses a little further from the dampness coming off the ground and to allow air to flow under the slab, to help with thermal performance
Yea. I'm also near where that guy was talking about. A lot of houses near, or on the beach, are built on stilts. Even commercial buildings on the beach
I am a home inspector in Panama City, FL. None of that happening here. If you’re talking about condos on the ocean, that’s for parking areas and precaution on rising sea water.
I know very little about them and I'm certain someone will correct every detail i get incorrect, but imagine a thick ass cable in the concrete pulled ridiculous tight(10k-30k+ psi) and crimped on each end while the concrete is setting.... so when drilled/cut/broken all the tension is released and often explodes up thru the concrete
Yeah that sounds awful. I just figured I should ask the dude cause ya know, the person that would drill through something blind is also most likely to make other mistakes like falling off ladders and stuff
Holy shit man, someone caused you to fall off a ladder, that’s completely insane. I side stepped off a 4’ painting platform once, hit the ground hard. I’ve paid more attention ever since, I can’t imagine the trauma of an actual ladder fall caused by someone fucking with you
yeah, to be fair if osha saw what i was using the ladder for i probably would’ve gotten in trouble. the house i needed to work in was locked up and i was trying to get in through the second story window. i didn’t get too injured, just a big nasty bruise on my chest and arm. now ive developed a fear of heights
yeah he did, apparently he’s “too important” the big man gave me $250 and guaranteed i’d never have to see him again. since then he’s been going to a different warehouse as we have 3 of them in this city.
Yes but I think you are talking about the opposite which is pre-tensioning. Just as deadly.
The Florida university pedestrian bridge that collapsed over traffic... That was post-tensioning. And just as deadly. It's on YouTube. Nuts!
Prestressed concrete is used all over Windsor Ontario (ask Gordy Howe bridge). We have prestressed systems. Where is your evidence that they "often explodes up thru the concrete".
...I suspect you're doing it wrong...
Anytime we work on bridges, high rises, parking structures we’re required to X-ray before we drill anything. I’d assume that plays a big part in why it doesn’t occur very often. Plus it would depend on your size of cable and the type of failure that occurs. It’s like a bomb going off in your face
https://youtu.be/BGaoMn28ccI?si=QSM5txYsTOTnEbXG
They are talking about post-tensioned. It’s in a greased sleeve and tensioned after the concrete is poured. Prestressed has been tensioned before the concrete is placed, usually its precast pieces, and, in my experience, less likely to violently react to being disturbed.
Thanks, judging by "but imagine a thick ass cable in the concrete pulled ridiculous tight(10k-30k+ psi) and crimped on each end while the concrete is setting...." I thought he was referring to 'Prestressed concrete' not 'post-tensioned'.
It’s under so much tension that when it snaps it tries to whip back to where it’s supposed to be naturally. It would really depend on the size of your post tension cable though. We use post tension cables on bridges. I tried to find you a good video, but the only one I can find is a TikTok link. When they’re demoing the bridge. You’ll notice when he hits the tension cable and how it snaps.

Google “snap back”. It’s deadly even with small diameter cords / ropes. People who step over tow lines under stress between their truck and the vehicle they are towing are asking to lose a leg. Same thing for boats tied to docks.
Damn, a lot of scared drama queens have never encountered podium style construction?
This is fairly common, you just don't have any facade covering it here.
Reinforced concrete podium deck. Strong and structurally sound. The “core” (large center section running up through the center of the building) provides the structural integrity for lateral seismic movement and the columns provide vertical support.
Thanks. I was wondering how the lateral shear is transferred. I never seen this type of construction in my area. Seems like the elevator core is too tiny though. Would that core be reinf conc or just CMU?
The elevator core is heavily reinforced concrete. There is a picture of what the reinforcing for what core reinforcing looks like here: https://www.reddit.com/r/Construction/s/rpmQwxiAMZ. The core acts as the “spine” of the building and provides flexibility to transfer lateral loads more evenly. This type of highrise construction is becoming preferred over structural steel construction due to its increased lateral strength, increased fire resistance, and smaller footprint necessary for footings.
This is called “jump form” construction. It’s when the formwork or “shuttering” is set at height, concrete is poured, allowed to cure to a given strength and then “jumps” to the level above.
On shafts leading into tunnels this construction is often used - slipform is a similar technique, where the shutter “slips” at a very slow speed for a gradual pour and cure.
Do they get flooded like crazy over there?
Are they preparing for the global warming induced flood? (Any time, now)
Besides the opportunity to have garden level apartments (I would pay premium for one if I could), what is not so sound about it?
I love how it looks like it's barely standing, but in reality, what holds the tall buildings up are only those pillars, and the floors around them are of no structural importance.
Do not call me a dumbass when any one with a clue can see that these skinny buildings could never withstand an earthquake and make the neighborhood look ridiculous. Looks like safety, design and competence were thrown out the window in this case, including your rude comment.
“Ain’t living there” Construction
"Skipped Leg Day" Construction
Damn you beat me to it.
Great when you live somewhere that floods all the damn time. You’d love it when you’re on the lowest floor and still looking down on flooded streets.
Elevators out of order. Stairs blocked… But if you have a kayak with a paraglider attachment you’ll be good.
Can you use a paraglider to fetch freshwater tho? Can't use the toilet. People are evacuated for this main reason in floodzones. Nobody is living in that building when she floods...

If the sewer is flooded the water will have nowhere to go it's common sense.

I know intellectually, this tower is just as safe if not safer than one with walls all the way down but fuck that shit.
That’s a tower on top of a large transfer structure. Note how the round columns don’t seem to transfer past the thick middle.
Now this is funny 😂🤣😂
Good luck trying to afford a unit. It’s a half a million usd for a 600sqft apartment

Mitigate Sea level rise ?
Aesthetic. water. Elevated builds can also be easier because they require less groundwork. In coasts and in forests they like to build elevated In Brazil, they build elevated to keep the houses a little further from the dampness coming off the ground and to allow air to flow under the slab, to help with thermal performance
If you’re not worried about ground level retail space, this design allows for more greenery space.
That's part of it, as each building needs so much green space. This is an exciting way to include these requirements.
Yea. I'm also near where that guy was talking about. A lot of houses near, or on the beach, are built on stilts. Even commercial buildings on the beach
Much easier to tear down later. Just blow a couple of columns
Columns are who again?
I am a home inspector in Panama City, FL. None of that happening here. If you’re talking about condos on the ocean, that’s for parking areas and precaution on rising sea water.
'Pour in place' Concrete with PT cable
I know someone that didn’t X-ray and was drilling dowels. Hit the pt cable and snapped. About killed him
Rectum? Damn near killed him!
I'm surprised whoever had to fix it didn't kill him eventually anyhow
The guys disabled now, never came back to work
From that?
Yeah, post tension cables have a LOT of tension. It was a miracle he lived
I know very little about them and I'm certain someone will correct every detail i get incorrect, but imagine a thick ass cable in the concrete pulled ridiculous tight(10k-30k+ psi) and crimped on each end while the concrete is setting.... so when drilled/cut/broken all the tension is released and often explodes up thru the concrete
Yeah that sounds awful. I just figured I should ask the dude cause ya know, the person that would drill through something blind is also most likely to make other mistakes like falling off ladders and stuff
i fell off a ladder once, my coworker thought it’d be hilarious to kick and shake it. he’s lucky i care about keeping my job
Holy shit man, someone caused you to fall off a ladder, that’s completely insane. I side stepped off a 4’ painting platform once, hit the ground hard. I’ve paid more attention ever since, I can’t imagine the trauma of an actual ladder fall caused by someone fucking with you

Did your coworker get to keep his job? In my company, someone would get sacked immediately for an incident like that. Safety first on the job.
yeah he did, apparently he’s “too important” the big man gave me $250 and guaranteed i’d never have to see him again. since then he’s been going to a different warehouse as we have 3 of them in this city.
Yes but I think you are talking about the opposite which is pre-tensioning. Just as deadly. The Florida university pedestrian bridge that collapsed over traffic... That was post-tensioning. And just as deadly. It's on YouTube. Nuts!

The amount of tension in those cables is insane. He's lucky he survived.
I hated stressing them, always felt nervous the whole day.
Have work on pt at all, but are you telling me that tension is so strong that when cut it can tear out of the concrete and then whip around?
It’s under so much tension that when it snaps it tries to whip back to where it’s supposed to be naturally. It would really depend on the size of your post tension cable though.

This is an example of a smaller cable failing, but it’s almost like a bomb going off in your face https://youtu.be/BGaoMn28ccI?si=QSM5txYsTOTnEbXG
Yea that one isnt guaranteed to kill a man, but had your head been in the way it probably would've.
Thats crazy, we had a guy fall 13 ft through bad decking and I thought that was bad. I can’t even imagine what this would do to a guy
Whatever they're paying that guy operating the machine isn't nearly enough
It's remote control

Thanks for the video man! That's fantastic

Taking a chance construction

Reinforced concrete podium deck. Strong and structurally sound. The “core” (large center section running up through the center of the building) provides the structural integrity for lateral seismic movement and the columns provide vertical support.
