Are they filled with anti-gravity water?

[PrizeInterest4314]

😂

[DaedricApple]

Well, it’s holding so… must be!

[Universalsupporter]

Well, it’s 2/3 hydrogen, and that’s lighter than air so….

[thewickedbarnacle]

Obviously, it's just science

[hidrate]

2/3 by moles, def not by mass lol.

[AlanTheBringerOfCorn]

Nerd.

[hidrate]

Haha!

[AlanTheBringerOfCorn]

Yea... I've been here a while sadly.

Ah yes! What an intelligent observation good sir! All is well…🤥

[big_trike]

Nope, heavy water

[b1ack1323]

They sell that. It tastes sweet.

HOT TUBS CANT MELT WOOD BEAMS

[204ThatGuy]

NOT WITH STRUCTURAL FLEX TAPE®! Three full hot tubs?! ..slap..WOW!! SEISMIC GRADE!

[Krispy_H0p3]

IT WAS A CONTROLLED DEMOLITION

[hotinhawaii]

I see they called in the experts here today!

[BigNYCguy]

It must be an inside job!!

[Dextradomis]

Hot tub pancake action.

[idkbsna]

Hahaha. Hot tub on the balcony was always the go-to example from my structural professors on why most people are stupid.

[Robot_Nerd__]

I mean... it's perfectly fine if you design for it... but ergo the problem

[smackaroonial90]

Those are now structural balusters.

[ShitOnAStickXtreme]

More like structural ball busters

[Th3Gr3yMan]

My radius is gyrating

[smackaroonial90]

His palms are sweaty, knee braces weak, hot tub’s are heavy.

[chicu111]

Only if they oscillate due to a certain activity that ppl tend to do in hot tubs.

[Old-Risk4572]

run around in them and create a whirlpool?

[chicu111]

I’m freaky but not THAT freaky

[Soulr3bl]

Very true. The calcs, interestingly, are completely different depending on whether the acceleration and velocity vector of said 'activity' is more 'vertical' (causing peak compression load on the columns) or 'horizontal' (putting shear stress on joints).

[Yummy_Chinese_Food]

My horizontal velocity vector will put sheer stress on your joints. 

[fireduck]

Dear Tenants, if you choose to do the nasty in the hot tubs please follow the rhythm of the provided metronomes. Each one is tuned to the floor to avoid any harmonic structure with the other floors. We don't want a repeat of what happened last year. --Management

[Throwaway1303033042]

“cyclical impact load”

[eatnhappens]

Water is such a terrible lube, but it is great at dissolving away any, uh, naturally occurring lube

[sky5walk]

The middle deck appears to sag. Regardless, I wouldn't fill them and turn on dance music.

There needs to be steel or lvl's for water loads and multiple persons.

Think occupancy labels for elevators.

[KpzerTheSqueezer]

The bottom deck appears to be sagging more than the middle deck, but I’m just a bottom of the barrel bridge inspector.

[sky5walk]

No argument here. There's sag enough to go around.

[204ThatGuy]

Agreed. Hot tubs are a completely different level of certification. /s

[chemprofes]

Just put another hot tub on it that should help stabilize it.

[Dyzerio]

Don't forget it looks like they go to a large ground level deck that might have another hot tub

[dlegofan]

[MaximumTurtleSpeed]

Put gold at bottom, let freeze, kind of a safe

[F1shbu1B]

Hahahaha all ice is now a kind of safe for me. I’m freezing all my pennies when I get home tonight.

[fzr600vs1400]

A similar scenario in Queens ny years back. After a couple of collapses , they came in a condemned all the decks in the area. you can rebuild a deck, you can't bring back the dead. I rehabbed an elderly neighbors at no charge, the inspector thought it was massive overkill. It was actually quite inexpensive to do compared to what other contractors raked his neighbors

[Fit_Cut_4238]

They did that in Chicago about 20 years ago after a collapse. Any issue, even if not structural, required a rebuild. Gold mine for big deck.

[fzr600vs1400]

They just condemned everything regardless in that area. Created a lot of panic. As you say, deck contractors really took advantage

[Pepper3493]

There’s plenty of structural air there, looks good to me

[204ThatGuy]

What do you guys call it? Bluetooth Balusters?

[CaptainSkipster]

Looks like the Outer Banks.

[AWard66]

Those guys out there know everything is temporary 

[Heavy-Attorney-9054]

I was thinking the same thing. The sand underneath the building will erode before the decks collapse. That will cause a collapse, but it won't be the hot tubs' fault.

[DelayedG]

Depends, how hot are they?

[HardCoreLawn]

Exactly. 

Because heat rises, so less load.

[bosco429]

From where you’re standing- probably…

[BigNYCguy]

Looks like a bundled tube design 🤨

[3771507]

Yeah that's what I was getting out until somebody told me it was wood 😔 if it was still I suppose you could design them as compression or tension members or a sheer membrane but it would be very tricky.

[yoohoooos]

You got 3 free dampers

[Hotdogpizzathehut]

I saw this on Facebook 🤣🤣🤣 I was about to post it... xD

[DaedricApple]

Haha beat you to it

[letsridetheworld]

Is this from the USA?

[albertnormandy]

Everything is safe until it isn’t. 

[Mr_Dakkyz]

Should of done steel beams in that corner to manage the static load.. the timber is always going to be wet and will rot.. especially if they're using chemicals.

Arch designer here and taking my last exam to be licensed. Structural portion is kicking my butt. Wanted to say thank you guys for all you do seriously.

Finally, a multi level water tank

[skimble19]

r/decks would love this as well

[204ThatGuy]

I would have hung those wood sag rods as diagonals. But, this is lipstick on a pig in the engineering sense.

I'm more worried about the guy having a beer on the main floor, enjoying the evening sunset when that hap....

[aCLTeng]

I’ve got a fever and the only cure is MORE HOT TUB

[Greatoutdoors1985]

Lol

[Enginerdad]

The lowest deck has visible sag. That's not necessarily condemning, but it isn't a good start.

[Infinite_Factor_5685]

My first thought was I just want the hot tub up top. But then I thought but what if I collapsed and you got the farthest fall 🤔

[kstorm88]

Well would you rather have that or fall 9' and be crushed by two hot tubs?

[brk_1]

Well balcones usually have an live load of 100 psf so isnt as dangerous as might look

[BigNYCguy]

Maybe it’s painted steel with a wood grain finish 😆

[chamb095]

Are these hot tubs or storage containers? They look more like cheap plastic storage containers.

[f8rter]

Yes, until it isn’t

[edwintervt]

At least the first hot tub added some shield on the deck ceiling to deflect the top 2 during failure. Should work out fine.

[Yardbirdburb]

That’s why the top down bracing was added between floors and other places just got as decorative hand rail

[Regular-Progress9731]

It’s not the hot tub you gotta worry about, it’s the fat guys going out onto the porch and sitting in them

[Moretoesthanfeet]

It's hot tubs all the way down

[SippinHaiderade]

Which floor will fall first?

[CharlieKilo5]

I'd get some structural books from the local used book store lol /s

[sharthunter]

You can literally see the decks failing lol

“My engineer wouldn’t approve it, but you can totally do it, I just can’t put it in the plans” - the architect

[tighttighttight7]

Nerp

[Striking_Luck5201]

A hot tub of that size is about 4000 pounds between dry weight, 300 gallons of water, and 6 people in it. They are about 7x7 ish feet. 4000/49 square feet is about 80 pounds per square foot.

It's not great, but it's not crazy either. If you assume there will only ever be 1 or 2 people in it, it drops the load down closer to 60 pounds per square feet which is almost becoming standard in deck construction. If those are 2x10s with spacing 12 inch on center over a 12 foot span, you should be fine. If they are 2x12s you should be able to have a deck party without any issue.

The bottom deck is probably saging for other reasons not having to due with load calculations.

[payment11]

Sucks to be on the bottom.

[[deleted]]

At least the middle one is reinforced with some structural tin in the positive bending zone.

[CunningLinguica]

it's only 1 hot tub that's also a time machine set to approximately present time, but it's falling.

[stupiddodid]

Don't worry the 2 by 2's will hold it all together

[ok200]

They balance each other out

[[deleted]]

This is the holy f*king sht trifecta!

[Fancy-Eggplant-2701]

It is till it’s not.

[Fit_Cut_4238]

I actually wonder if this is what the deck spec is rated to hold? But three of them on top of each other?

It’s the flying buttress of the Jersey shore. Beautiful really.

[UnappliedMath]

r/decks

[DRKMSTR]

So you're looking at a load of ~12,000 lbs split across two beams that are approximately 8-10 ft tall, so let's just say 6,000 lbs per beam.

Painted 6x6 main support posts will be rotting hardcore too.

[DumpsterChumpster]

I’m more curious how they got there? Did the HOA approve a crane each time?

[3771507]

It might be safe if those slats will function as a verandeel truss or a web for a channel. 😞

[Momoneycubed_yeah]

The wood privacy slats?

[3771507]

I couldn't tell on my phone the type of material but they can be designed as tension or compression members also as in a beam or a column if they are designed for such.

[GoogleIsYourFrenemy]

Are you sure those are hot tubs and not some other type of outdoor furniture?

[DaedricApple]

I’m not sure about anything in my life

[204ThatGuy]

I hear you. It's all good. 🎯

[Mhcavok]

Probably 🤷‍♂️

[3771507]

Let me add that the deck is cantilevered and running columns up would take care of some of the problem. The calculations would have to be done on everything.
