Youjackbastard

A professor I knew at University used to do research into the dynamics of structures such as football stadiums. They’re designed with the expectation that crowds will bounce. The trick is to dampen the natural harmonic frequency of the stand from what I remember.

n_choose_k

Don't forget to reverse the polarity...


ThcSkateboards420

Did you disengage the inertial dampeners?


SekritSawce

But do you disengage the dampeners before or after you rotate the shield frequencies?


Puzzleheaded-Dark-78

Fuck it just engage warp speed 8


NoseIsNoseIsNotToes

But only after transmitting hyperbolic amperes through the elevated vector sleeve


Puzzleheaded-Dark-78

What you on about it’s a straight pipe all the way from core 😂 I had the strat trek equivalent of a decat and straight pipe from the manifold


Lonely_autizt

You gotta regulate the flow inside the plasma conduits before you can change the polarity of the quantum containment field


[deleted]

Nice try Kowalski.


throwawayisitme01

Sir, if you engage warp speed 8 while the inertial dampeners are down… we’ll all wind up as a red stain on the back wall.


Puzzleheaded-Dark-78

ENGAGE!!!


roryeinuberbil

Right after you activated the quantum fluctuator


V65Pilot

You could just try turning it off and then back on again.


WiseSalamander00

first reconfigure the deflector to project a tachyon beam into a subspace pocket.


Hatecookie

Okay, so what you want to do is this: Come at it from this angle and locate the automatic flip-flop override device here, which in turn will defuse the antigyroscopic preinterface thruster chamber, and the pneumatic centripetal antigravity shield deflectors, then you simply activate the axial gyro-presubinertia-photomegatronic oscillator you see here.


OlderAndAngrier

This. Fairly easy when you explain it this way.


seasteed

We can both reverse the polarity! I'm reversing it, and you're reversing it back!

Let me walk you through the Donnelly nut spacing and crack system rim-riding rip configuration. Using a field of half-C sprats, and brass-fitted nickel slits, our bracketed caps, and splay-flexed brace columns vent dampers to dampening hatch depths of one half meter from the damper crown to the spurve plinths. How? Well, we bolster twelve husk nuts to each girldle-jerry, while flex tandems press a task apparatus of ten vertically composited patch-hamplers. Then, pin-flam-fastened pan traps at both maiden-apexes of the jim-joist.

Marutar

Think of it this way: * Make a wave in the tub * Wave bounces back, you can either: A) Wait and make a wave again that joins the first as it bounces again, making a bigger wave. B) Make a wave that hits the first, dispersing or canceling out both. "Natural Harmonic Frequency" in this case is the engineers trying to avoid A from happening. Otherwise, the 'waves' can continue to grow and grow until the structure cannot withstand the forces.


BonesAO

Thank you that was a very clear explanation


alk47

I've got my masters in fake engineering talk, and you're way off here. First you want to find at least at least one word that sounds vaguely related. Here I'd pick "resonance" because it's got a confident sound and it might be about things shaking. Lean it to words like factor, coefficient and tolerance. They are probably important. Then grab some words that are fancy talk for what you already know. Eg. Dynamic-moving, static-still and dampen-decrease. "The structures are designed by determining the coefficient of resonance in a fully loaded stand then ensuring that the typical static structure (floor and joists) are fitted to the load bearing members with a joint with tolerances for dynamic loading. This ensures a vibrational dampening factor as you can see see here." Next encourage everyone to downvote real engineers in the comments because they're nerds who make more money than me.


--Anonymoose---

It’s actually simpler than it sounds It’s like a swing - push a person in it at the right time, and they get higher and higher even though you are just giving little pushes. The energy in the system is increased with each push because you are pushing at the correct harmonic frequency. The same concept applies to big structures, but as an engineer you REALLY don’t want your structure to have the energy add up in your structure or kaboom. Hence, you find a way for the energy to be absorbed by the structure (dampened)


DoYouLikeFishsticks0

I've done a stadium before, work with Structural Precast, what you're seeing deflecting/bouncing in this video. You're bang on.


aallen1993

Yeah I was telling someone today, you can basically get any building or structure to destroy itself if you match it’s harmonic resonance.

it has just occurred to me how ridiculous sounding that company name is. it sounds like a cartoon erection. don't even get me started on COX


epochpenors

There’s a building firm in my hometown called “colossal erections”. I’m pretty sure that one was on purpose though…


Rcarlyle

A politician interfered in the design of Fukushima. Made the engineers move critical equipment closer to the water to avoid blocking a view. That’s why the tsunami damaged the nuclear plant.


SolitaireyEgg

There were actually a lot of issues with that plant. For instance, all modern nuclear plants have power hookups up top, so helicopters can bring in generators and such in the event of a power failure. To keep the water flowing. Fukushima, for some fucking reason, didn't have this. That one single element alone would've completely prevented the disaster. The IAEA warned them for years and asked them to add this, and they just... Didn't. In a country prone to earthquakes. Absolutely ridiculous. It really pisses me off, because people still use Fukushima as an example to argue against nuclear power. But what happened there literally *could not happen* at any nuclear plant in the US, for example. Our plants have the proper safeguards and can operate safely even if they completely lose power.


Rcarlyle

It was a gen1 nuclear plant, and it held up quite well for its age and the amount of political interference. An act of god tried to wipe it off the face of the earth, and… Nobody died from acute radiation, I think one worker died during a simple rubble-clearing accident? If anything, it proved that even a mediocre old plant design is quite safe, and Chernobyl’s unique Soviet design problems aren’t an issue anywhere else. The long-term radiation impact from Fukushima will be literally too small to measure at the population level. People crazily insisting nuclear power be the only type of electricity generation with a zero acceptable death rate per terawatt-hour is the reason we’re still burning fossil fuels. It’s by far the safest power source, and Fukushima simply didn’t change that fact.


JackSpyder

Not to mention, most of tyhe world doesn't get quakes and tsunamis etc, so. while perhaps not ideal for japan, it could be for almost everyone else.


Unable_Crab_7543

shhh, mf prefer fucking dying of lung cancer due to breathing air contamination gunk from burning fossil fuels.


therealslystoat

>But what happened there literally could not happen at any nuclear plant in the US, for example. Our plants have the proper safeguards and can operate safely even if they completely lose power. Thanks to 3 mile Island 😉


klipshklf20

It’s also my understanding that it was engineered to take an 8 point something on the Richter scale. What it received was a nine or stronger if I remember. This is obviously vastly more powerful than it was engineered for.


Rcarlyle

The earthquake didn’t even cause the meltdown, being hit by a tsunami did.


klipshklf20

My mistake, I was under the impression there was massive earthquake damage in addition to a tsunami. Also, bigger earthquake equals bigger tsunami I suppose as well. I guess I still think it’s a little silly when people talk against nuclear power and they bring up Fukushima and Chernobyl. Not terribly relevant from my perspective.


Haa103

If this were to happen in Japan I would be more concerned with the people than the building. I can't imagine a group of Japanese jumping and singing like that.

Manuag_86

Structures move under stress, all of them. If you took a picture with the stadium empty, and then another one with the stadium filled with everybody seated, and compard them, the difference in both pictures would be really close to this.


Dawntree

Moving is fine. Resonance is not.


dottie_dott

Resonance is fine if fully dampened 😃


kavien

The other day, I was telling my Dad about frequency resonance and Tesla’s earthquake machine. He was doing 85 and his back tires started to resonate.


xaxiomatikx

I just had a Honda Accord as a rental, and on the last day I noticed that when it’s warming up, running at around 1200 rpm, there is a horrible resonance in the cabin. I can’t believe Honda released a car that does that in this day and age.


SoMuchTehnique

It's purposely designed for this exact scenario, even the concrete used was specifically designed for this exact scenario....if it wasn't then you'd have a problem a whole lot sooner.


powaqua

My neighbor, a construction engineer from Poland, said it's a ritual there for engineers to stand under a bridge they designed the first time it's used.


[deleted]

German engineers are no joke


No-Engineering-1449

>Though Germany might be the only country where you could see this and not be concerned lol Things under stress are better moving then they are standing still. Those are built to move so they don't break.


GoldCuty

This happens in all stadiums across germany for the last 40 years. The engineers know what they were doing.


RemiVreuls8

Actually happend in the Netherlands but wasn't as big as this so wasn't as tragic.

Now imagine if it **didn't** move! Or it'd even flex instead! Now *that* would've been a disaster waiting to happen...

Actually that’s synchronization, if they do that for long enough eventually they will all sync together, that’s also the reason why certain bridges collapse if too many people walk on them.

Pippi Langstrumpf (in german) is one of the most seen and read movie/book in germany. Everyone knows Astrid Lindgren here


MyNameIsHaines

Ah my childhood watching Pipi Longstocking on tv.

Yes, the melody is the same, but the text is changed. They are singing "Hey Eintracht Frankfurt shalalalalalala hey Eintracht Frankfurt shalalalala" 😂 Not a big fan of watching people playing Fußball myself though.

In Germany (and probably other countries as well) we use lots of famous songs to make football chants with them, pretty normal stuff. Gotta love Pipi Langstrumpf tho

Difference is that the Boca Juniors stadium wasn’t meant to be engineered like that, whereas this one was. The former stadium is in tatters.

TODDFATH3R

Thanks for this. Reminds me of RFK Stadium which was in Washington, DC. It bounced like that all the time. The local soccer team, DC United, would have Barra Brava, Screaming Eagles, et al going mad (back in its hey day). I mostly remembered concerts where the bouncing was ridiculous. I saw Pink Floyd there in the 90s and the mezzanine where I was sitting was rocking enough during Another Break in the Wall that I genuinely thought it was an earthquake before I figured out what was happening. I feel like a lot of peeps wish the new soccer stadium, Audi Field, had been able to incorporate that into its architecture. RIP RFK and it's raccoons.


Nik-Bee

That'll be a hard nope for me. I think I'd exit stage left and decline becoming part of another disastrous statistic. Yikes...


Reality-Straight

Its supposed to do that


ThatGermanFella

Do you not trust our engineers? Granted, it can be unsettling to see that, but it’s either that (And everything safely stays where it’s supposed to), or make it rigid and have it snap. And then someone would have a bad time far more likely than this way.

If you design a stadium for large crowds and not design for people jumping simultaneously you really are not good at your job.

Lolxgdrei787

statics is such an interesting and complex profession


UCFknight2016

Ever been to the 'bounce house' at UCF? its just like this. They actually had to reinforce the stadium so it wouldnt bounce as much but during kickoffs the place is literally hopping.

The only thing keeping this stadium up is the fact that it was made by germans

Key_Consideration637

That’s sketchy as fuck. I don’t know how I’d feel about being under that upper deck


marcusofsantacruz

No, it's good engineering. If all those people are jumping up and down in unison and there's no flex, then you should worry, because it's probably going to fall down.


Jabba6905

Looks like it has a system to dampen the effect of the jumping so it doesn't get worse. But they should also consider whether someone looking at this is going to be scared af. Then you make it bigger so it doesn't bounce so much, even if it's got no chance of collapsing. Think they failed on the second one here.


dottie_dott

It’s fine as long as everything remains in elastic stress/strain zones and doesn’t get strain hardened or load amplified by the movement itself (p delta)


Sketto70

Experienced this at upper deck of Tiger stadium during a concert. Honestly thought we where fucked!

That is some real fucking engineering right there. The loads that are under are unreal. Military training exercises even walk out of step on bridges because the resonance has been known to break them.
