Superdomes - Extreme Engineering - Big Bigger Biggest
This documentary reveals the technological leaps forward that have allowed some of the world’s largest dome’s to be built. The Oita Stadium in Japan has a colossal roof spanning a mighty 274 metres. A steel, Teflon and titanium structure over 270 metres across, and 60 metres high, the Oita’s roof covers a sports stadium big enough to seat 43 thousand spectators. At the flick of a switch its seats retract to reveal a running track and its roof opens and closes like a giant eye.
The film explores how this building was made possible through a series of six engineering breakthroughs. We explore how six landmark buildings - including the Pantheon in Rome and Florence Cathedral - each feature a major technological innovation that allowed engineers to build bigger Domes. Using computer generated imagery, this film reveals the incredible stories behind these super domes and the inventions that have enabled them to grow ever larger. Six ingenious leaps forward that enabled domes to evolve, from small, to complex and BIG!
Episode from the “Big Bigger Biggest” documentary series exploring the engineering breakthroughs that have enabled us to develop some of the largest structures in existence.

The Pantheon is such an incredible building. A building of such architectural complexity in such condition after such a period of time is awe-inspiring.
*_Dome looks so light that it might take off and fly_* ... The main arched trusses use triangulated space frame techniques. It is very strong but very light too. You can see through them to ceiling or sky overhead. The structure of the 2 movable dome sections are also amazingly light. Use of dome material in center is translucent and allow natural daylight to flood the playing field below. In fact, it is probably brighter inside when dome is closed because sunlight is very direct. Part of field or seating areas might be in the sun, while every where else is much darker. Closed panels allows diffused light to be scattered evenly over majority of field. I am a former Seattle resident... our Kingdome was largest reinforced concrete dome in world at the time. It outlived it's usefulness and was imploded by CDI. It remains largest concrete dome imploded and set a Guinness Record.
Air flow concept is from the simple design of the incredible rocket stove. I am surprised you did not give it credit. Thank you for your coverage on domes.
The actual Superdome in New Orleans outshines the Astro Dome and the Georgia dome by far!
Thank you ⚜⚜⚜⚜
London Millennium Dome: Hi! I'm here!?
Yeah but Astrodome came first and super done was very similar
The Oita Dome truly is awesome!!!
This show was so good. bring it back.
nah, need to make americas youngster stupid and gay.
It's amazing how much it can calm and soothe the mind and body.
A reminder that even the failures of engineering, like the retractable Kevlar roof, are valuable, because sometimes you only learn the limitations of a system or material if you attempt it at scale.
If it passes the paddle-pool test, then it's all good. 😹

There was a whole lot of corruption that needs to be factored in to an understanding of the Montreal Olympic games.
Who knew domes could be so interesting?
yes they are. just look it up in the bible. our flat earth is covered and sealed by a dome. nothing goes out nothing comes in. where do you think they get the idea from?
There's the issue also of large buildings and indoor weather.
Wow!!! that's amazing!!!!
I love that shortly after this came out, the national dome in singapore became the biggest dome
I learned a lot from this video
I'm a little and normale engineer I like this educational videos .
This is whats needed in remote areas & icy areas & desserts for people to grow their vegies & live under in a comfortable environment.
The Iota Dome is a beautiful elegant design.
love it!!!
Good job
Genius!
Very beautiful sweet video
I would add the Hagia Sophia in Turkey... Thank you for your impressive presentation !
It would be so simple if only a large stadium could be built using the same materials and dimensions based on a much smaller model. This is not possible as new dynamics come into play as you build it bigger. I give both thumbs up to the engineers would were able to design modern marvel and also give a thumb up to this video.
36:28 "robotic firefighters", such a japan thing to do
"Only once it's passed the childrens paddling pool test can it be rolled out across the dome" 🤣🤣🤣
The Pantheon is by far the most impressive, considering how many technolgical break throughs were required for it be stil standing. I doubt anything we build today will last 200 years, not to mention 2000 years.
It all comes down to cost and design intent. With an unlimited time and budget and a goal of creating long lasting structures, we could easily create buildings to last thousands of years, if we wanted to. But our goals are different. There's a saying that its easy to engineer a bridge that's standing, but its much harder to engineer that's just barely standing.
My uncle was an electrician on the Astrodome. It was a Houston,Texas landmark when it was built.
I did not mention that the cables hold what is known as the "Oculas" (score board) which itself weighs 100 tons.
Toronto had the first retractable dome in 1989. it was named the SkyDome. later, the name was changed to Roger's Centre. Let's see if they get their facts right in the video above... Nope. only human.
Surprised the Skydome\Rogers Center isn't one of the 6 domes
This what makes engineering so amazing, engineers takes ideas from past projects to implement present projects.
What else do you expect - do the same errors over and over again? Engineers and scientists are not politicians. Of course they learn from failure.
@@Enyavar1 burn!!
@@Enyavar1 oof
Can't wait for 360° dome, one dome to roll them all.
I want one!
only 40,000 spectators !!!!! Stadiums in the UK hold bigger crowds
Its still better than it was for everybody else , they arent going to be there for you when you need them the most
19:00 Bridge between the physical and the metaphysical/imaginarium/atrium
nice
These forms may actually cause less damage during extreme weather.
amazing
Never mind the sporting events, how about just for living? The dome could be made out of transparent solar panels, which exist now, which also filter out the sun's damaging UV rays. The air that is pumped in could be filtered and cleaned first, likewise the water. And, like those summer themed domes that people go to for for a bit of summer vacation in the middle of winter, the temperature and climate could be controlled as best suits inhabitants. Also, it would be legal to dress as Krusty the Klown in the dome.
Finland here, big domes please! -7°C to +2°C all week, snowfall , water rain. Either slippery and icy or wet and dirty outdoors. Sunrise 9:18 AM sunset 14;52 PM (it is cloudy, cannot see the sun anyway)...
The energy requirements in most climates would be impractical. You could do it, yes - but the benefits wouldn't justify the maintenance and power costs.
There you go. You have identified the problem and the market. Invent it and sell it. You'll be the richest person on the entire planet.
Ia this a good idea
You think the engineeers havent sent proposal about that? they all got snuffed out by oil and energy company. Disappeared in a hench night.
Live close to the west baden dome it's a remarkable building with a long history kinda creepy in the early hours they have always tried to keep the history alive tho lots of pictures from the 20s also a favorite hideaway for Chicagos gangsters especially Al Capone and his partners in crime
Best building ever, by 1000 years we are move up... Forested arabic peninsula will be second step to return back to Paradise..
The video did not cover how Oita dome takes care of the steel expansion problem due to temperature. Oita does not use rollers to allow the steel to expand. I wonder how they solve the expansion problem.
It was actually covered in the video. They mentioned they solved it by using detectors to the "rollers" to synchronize their positions with others in case of steel expansion due to temperature.
@@markiel55 thats actually for the roof closing system. i guess because the roof is so massive the force causing it splay out like the old domes need it to be permanently fixed to the base.
Is the Rams stadium in Inglewood, Ca. included in your study? That stadium seats 80-90 thousand spectators. It has a cable supported dome.
Your an idiot
GREAT NOW HELP BUILD ONE ON THE MOON
Just like the Toronto SkyDome
OH SHIT the flat earthers will have a hay day with this lol
reminds me of ATT Stadium in Texas
What about the Johan Cruyff Arena in Amsterdam? It has a retractable roof and hosts 55.000 spectators.
Bad research. The biggedt dome is the Cargolifter Dome in Germany, it free-spans 360m and now hosts a tropical landscape.
Jose Delgado , good job engineer , architecture , impresionant super big structure / Puerto Rico Caribbean
Very BIG ⚽
Why no mention of the Principality Stadium in Cardiff? Sliding roof oped 1999.
I'm just here to read all the arguments amongst apparent engineers.

The sound track at 30:25 reminds me of some old show on animal planet I think or discovery
Very interesting video. It makes understanding the firmament seem possible now. Firmament is still a dome type structure, just on a massive scale around 24,000 miles in diameter.
Fucking what... LOL
@@kindlin Don't you think it's possible from watching actual examples of the engineering required for a self - supporting structure ? I like the part of the structural ring placed at the base of the domes. Pro tip: people might listen better if you skip the profanities. Just saying
i didnt see the flathead sign
@@skipmagil My bad, I forgot it, at your mom's house.
@@12344567ist You're post and subsequent reply hardly deserve much better. Your opinions expressed in this thread are that of the most brainwashed of sheeple, hoping in vain to be the hero of your own story with no idea how to actually do such a thing but to proclaim _I'm right and you're wrong, I know and you don't._ Sorry, it's just not that easy.
Retractable roof in Montreal was built for the 1976 Olympics, not 1987.
*_PACK YOUR THINGS, BOYS! WE'RE GOING TO MARS!_*
What about the Toronto SKY DOME. I think it was long before this one where the roof opened.
The Toronto Sky Dome hasn't been completed yet. It should be complete around 2078. I can't wait.
Lots of retractable roofs, I thought it odd they skipped from the failed attempt in the 70s to the Oita dome, like there'd been no other progress in the last 40+ years.
As a black African-American man, I would like to say congratulations to the Japanese people and Engineers. This is very beautiful engineering all the best blessings to the people of Japan.
Why aren't there any African American builders?
for this story, why does it matter what color Your skin is?
Too much loud background noise. I have to keep jockeying my sound control. Very distracting.
roman engineering is so incredible
I suspect you could talk to the North American Eskimo people of you want some hints into how to recreate the Cupola del Brunelleschi
what were the tension rings made out of on the Pantheon
Yeah, they didn't tell us that
You have not even mentioned Araneta Coliseum in Quezon City, Philippines which was the largest coliseum when it opened in the early 1960’s. It holds its records until 2001 when the Oita Stadium in Japan was opened. (See Wikipedia)
no mention of Buxton Dome?
I wonder why they didn't talk about BC Place in Vancouver ....its amazing to see what they did with it ..
Mate I once stayed at the beautiful Trump hotel in Vancouver. Second only to the Shangri La.
The only thing I do not like of this particular episode is the fact that they focus on Montreal's failed attempt and not at Toronto's triumph. The Rogers Centre has the world's largest retractable roof and has been since it was built almost forty years ago. Canada is not all about blunders people.
Center... AND NO ONE CARES
@@allentoyokawa9068 F
AH, CANADA DID IMAX TOO!!! AND THEY LET BLACKBERRY FAIL. I STILL CANT FATHOM IT.
I didn’t see the whole thing thru. Any discussion of domes and dome structures cannot leave out Bucky Fuller and his geodesic structure, his American Pavilion in Montreal.
They forgot the dome light in a car. wink wink 😉
Thank you . ( 2023 / Jan / 09 )
Interesting that the superdome in New Orleans wasn't even talked about.
Singapore National Stadium: And I Took That Personally
Civic Arena , Pittsburgh, PA, USA
by adding air into a fire situation? wouldn't it fuel the fire?
Sire, the air flow is for the smoke, the water is for the fire. Airflow wont feed the fire as much as the already-existing air inside the stadium.
Is it tornado proof?
Next: Starship Megarocket
Nowadays, Oita Stadium was named as Resonac Oita Stadium since 2023 which is formerly as Showa Denko Oita Stadium before it was merged the company
Can't believe you left out The King Dome
Looks like a ladybug. Also, the hole in the roof of the Pantheon wasn't to save weight, it was to insure that the roof didn't collapse. If they had filled the hole in the roof in, the translation of the forces of the roof would come to a single point. No building material available of that time would have been able to withstand the translated forces at a single point, it would have just crumbled under the load causing the structure to fail. Instead, the builders used an arch (a complete arch would be a round hole in this instance) to spread the load to the surrounding material. Any structural engineer would be able to tell you that this is the reason for the hole.
A dome is an arch.
That's not really how a dome works. The central point will be under pressure from all directions, but it won't be some kind of singularity point where no material can resist the compressive forces, not when everything is all rigidly connected together as one giant mass. Doing a simple 2D free body diagram to get a feel for arc action, I got that the total horizontal stress at the apex would be on the order of the total load resisted and a factor of B/4H, where B is the total width of the arc and H is the total height. So, if you make a tall arc (H/B>4) the horizontal load at the top of the arc could be less than the load you're holding up. Going from 2D to 3D will only have a small affect, as you add more load, but you have more material. Typically, accounting for full 2-way action (like as you can do with 3D modeling), will get you lower stress than simple 2D assumptions.
You're reversing gravity.
Weight,pressure,load there all stressors at the centre point so they had to omit the centre point to prevent the stressors
Can’t believe 18 people believed that
No mention of Skydome Toronto Canada
An additional 15 mins longer than necessary with constant cliff hangers rewinds and non essential information ; fire burns water puts out fire simple no need for a 10 min animation to explain
Wait wait wait what about the New Orleans Super Dome!
❤❤❤
❤🇱🇨 #brilliant
They talk about the first dome beyond the ice wall
What about the London dome, Called the Dome (Today’s O2 center)?!
I’m at 2:31 into this fact filled documentary and I just have to say, I for sure do not envy this structure let alone any human being on planet Earth.I Envy none of YOU!🤨
🙋Craft carries are hundreds of meters and things like kitchens feed🐥 thousands beach ⛱
Big - bigger - boooooom
❤
The largest dome on Earth is above Earth.
No mention of the geodesic domes, why is that?
We still haven't matched the Romans. The Circus Maximus in Rome could seat 250,000!
5:30 Everyone on Facebook believing doomsday be like
what kind of 3D Software are you using?
Except now the largest dome is the Singapore stadium’s dome
Using the Oita dome design, how large could this dome be made given Martian gravity?
8
Japanese already proposed a 10 km mountain-like structure with concave strut. I think theres youtube video somewhere.
so i'm not the only one that played too much 'civilization'
I am unimpressed by this dome. If it had no trusses over the aperture, then I would have been wowed.
Only 40,000 seats?
