Built on Rubber!

[1103mix1103]

I made a mistake.

×the bridge

○ a bridge

I have watched the news that some stray cats are settling in between a bridge and its pillar, on TV before.

(>_< )

[1103mix1103]

I have watched the news that some stray cats are settling in between the bridge and its pillar on TV before, but I have not ever watched the news that such rubbers are in between there.

( ﾟДﾟ)

[komattaaa]

0:18 The bridge also keeps an bird's nest :)

[Flankymanga]

ohhh i think our highway builders should go look to japan for modern technological marvels like this one....

press pause button

hold down F11

stress test :)

[ahhhhhron]

that genius

[ComicPlague]

We actually have some very similar things in the US,,, altho they are on a little smaller scale for buildings, usually something like Teflon coated slide bearings. There are also the rubber ones for the larger structures like the new wtc.

[LittleKiseop]

That was interesting, i didnt know that :D

[kostyxaz]

I think you should put your voice on top of the original video's audio or make the original audio a bit louder, it's very quiet besides your voice =D

[MrJohn1966elliott]

I hope, it will be works.

[darkyoda]

Japan also pionered a type of railroad that has the tracks built on what is effectively rubber sleepers (or ties.) However this isn't done to help with earthquakes, though I'm certain it must, but instead to quiet the sound of the train. Making them less likely to intrude into peaceful areas.

[ReccaDreamer]

This is quite interesting really. Japan is great at engineering such things indeed. That's why it is rare that a huge skyscrapper would collapse in Earthquakes in Japan. Nice video by the way. :) Keep up with the interesting facts vids. ^_^

[depravedreality]

Very interesting idea. Logically it sounds like it would work nicely.

[2kageromaru]

Might as well build buildings and stuff from rubber... EQ problem solved. :)

[Kooletz71]

how long have they been doing that for? I would imagine that it would be degraded fairly quickly in the winter

[ChoppedLiver44060]

@Kooletz71 I initially thought the same thing, but then I thought about automobile tires.. I wonder how long it lasts though.

[Kooletz71]

@ChoppedLiver44060 yeah well automobile tires are constantly moving and being heated up, also you replace them fairly often, tractor tires on the other hand get really cracked up after a while

[RobertJFreemantle]

As always, great video. Interesting things that we want to see about the country we love.

[Nemesis093781]

Thank you for the video.

[Legendofsnake53]

Future builders in earthquake prone areas from around the world need to learn a few things from the Japanese!

[sagargdeshpande]

Hey ,I am from India who migrated to USA.After watching these videos I want to go to Japan.I really Love and adore your video.It takes a big heart to do this kind of stuff . I along with others appreciate it greatly.

[reshjuk]

For engineers this is not surprising at all. But thank you for showing us how it has been done with that bridge. There is no doubt the Japanese do this a lot for obvious reasons.

Another example is in Los Angeles, California. The City Hall is on top of elements which are basically vertical stacks of steel plates and rubber , and there are also shock absorbers horizontally. They installed them after a big earthquake. They had to raise the building by about 2 metres to do it.

[16thesoldier91]

nice and interesting peace of detail of japan never thought of that

[petitesalade]

i would have never imagined, very interesting indeed and great attention to detail! thanks

[Degenskonto]

How do you know its rubber?

[weurRTG]

@Degenskonto Well, maybe he asked.

[Capt777harris]

We have some of those rubber cushions in the San Francisco Bay Area under onramps and a few bridges.

[chibiariel]

I don't know why more cities don't do this.

[guguigugu]

@chibiariel they do :)

[chibiariel]

@guguigugu - Do they? Places in CA and stuff that get tonnes of earthquakes?

[guguigugu]

@chibiariel yes, there are even buildings built entirely on a rubber base. and rubberized bearings are common in many other applications where vibrations need to be dampened for some reason.

[chibiariel]

@guguigugu - Interesting. Thanks!

[cbunni666]

Wow. Is it actually effective? Or just one of those bright ideas that came the day after the big quake? Lol. Still cool. Keep up with the vids.

[FelixTheHouseFreak]

What happens after so many years and the rubber starts to dry and rot? Still a very good idea.

[LogiForce86]

@FelixTheHouseFreak That is if it's pure rubber and not something that's treated in a special way. Which I reckon it is, else I doubt it would get through the building regulations in Japan.

[Marh044]

always the most wonderful random videos that seem to educate you on the most small yet cool aspects of japan :)

[forgottenwinner]

Doesnt rubber lose its flexibility when its exposed to the elements?

[xTenshiAi]

wow, Japan is so amazing

[Cleavemyer]

so these are like the one building that is built on ball bearings to allow them to make taller buildings without fear

[StarDr0ps]

Huh, I never noticed that!

[SEThatered]

As an architect i can tell you that these blocks are a must for every long or curved bridge, as a compensation for a thermal expansion.

It comes is many forms: sliding plates, special joints, rollers, and rubber-like materials.

However i do agree that in Japan they are also calculate every structure to withstand an earthquake.

For example in this video the metal strips around this "rubber block" act as a crumple zone adsorbing kinetic energy and would be unnecessary otherwise.

[FHomeBrew]

@SEThatered There was a documentary about buildings in earthquake zones where the basements also contained HUGE springs to absorb the shocks and energy.

[hitachi088]

can you visit a LCD company? they are usually builded on big piston and rubber pad to absorb the vibration. Thumbs up so he can see it.

[Leecher4711]

I was always wondering how that infamous anti-earth-quake architecture was working ... so thats how it is! Thx!

[DvoracKode]

Rubbers for protection.

Allow me to translate. *ahem*

Mother Nature: f*ck you.

[singh4lyfee]

quiet a nicee idea, i like it 

[DuartChannel]

Of course it's interesting, I've also seen images of building being built on top of springs and other type of technology for the same reason as this.

[slopedarmor]

same as here, even though there are never earthquakes here.

[MrNadaname]

interesting :)

[SytheSlice]

I want a huge rubber boot :D

[kakapoable]

This is actually ancient technology called base isolation , used by the persians over 2000 years ago, the persians built huge palace's with this technology as (iran today) persia was very earthquake prone.

The Mausoleum of Cyrus is the oldest base-isolated structure in the world that is still standing.

[kakapoable]

Also very common in new zealand, in landmarks such as the beehive this is used.

[JL3Wind]

That's very clever

[SweetCash33]

Aha,

What did we learn today,

You can't stop nature,

But you can outsmart it...

[NigelGriff]

Just a quick question, why are most of your videos in 4:3 aspect ratio rather than the standard 16:9?

[enylive]

very intetesting and smart :)

[mellowsky47]

I found it interesting

[SakuraAvalonBleac25]

Nintendo plastic more usefull then i thought ^^ thank you for sharing this with us :D

[FeuVache]

I actually found that very interesting xD

[iFukuyama]

Nintendo-plastic is more durable than cement

[Gell1welt69]

Nice video as always

[barnabyjones786]

This is kinda like the bridges in Kentucky, like local bridges and bi-docks. Great Video :D

[hcsurfer26]

I don't comment on every single video you make. Just cause I am not sure what else to say about japan... They are always ahead of the amazement curve!!! I definitely always hit the like button when I watch your videos! Great work as always! Keep it up! =)

[AnimeHitsV2]

cool, I didn't know they used that on buildings/bridges

[lankeysob]

Pretty interesting!

[Fortheluvofmylife]

Thanks for making this video! Very interesting :)

[Fortheluvofmylife]

Woot! First to comment! :)
