Superdomes - Extreme Engineering - Big Bigger Biggest

[@SJR_Media_Group]

*_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!

London Millennium Dome: Hi! I'm here!?

[@connorcoultas9629]

Yeah but Astrodome came first and super done was very similar

[@communitycollegegenius9684]

The Superdome is multi-use. Oita seats 42,000 for soccer, while in some configurations the Superdome seats nearly 80,000 and has standing room for 20,000 more. I've attended rock concerts, football games, and even motocross racing in the actual Superdome. The Superdome is in the center of the New Orleans Downtown. All your other domes are out of town. The New Orleans Superdome is STILL the largest fixed domed structure in the world.

[@wackowacko8931]

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.

[@PatHaskell]

A dome is an arch.

[@kindlin]

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.

[@Cheka__]

You're reversing gravity.

[@kenroydick7743]

Weight,pressure,load there all stressors at the centre point so they had to omit the centre point to prevent the stressors

[@peterwan9076]

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.

[@markiel55]

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.

[@theshuman100]

@@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.

[@trespire]

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.

[@denisl2760]

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.

[@52memor]

only 40,000 spectators !!!!! Stadiums in the UK hold bigger crowds

[@falklumo]

Bad research. The biggedt dome is the Cargolifter Dome in Germany, it free-spans 360m and now hosts a tropical landscape.

[@moosefactory133]

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.

[@noble_JAKOB]

Wow!!! that's amazing!!!!

[@Mordred478]

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.

[@rikulappi9664]

[@dbx1233]

The Toronto Sky Dome hasn't been completed yet. It should be complete around 2078. I can't wait.

[@MrAlfable]

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.
