Hospital Survives 9.0 Earthquake | OPB

A seismic engineering method known as 'base isolation' allowed a Japanese hospital to survive a massive quake without even a broken window. Oregon construction standards do not require this technique, even along the coast.

Wow. I’m pushing 40 and lived through a lot of earthquakes, including Northridge. I never thought there would ever be an earthquake proof building. Ah Japan... You’re awesome.

[yoloswaggins]

Well I mean it's a cost calculation ultimately, if you have a certain amount of quakes within the life expectancy of the building, the isolation construction will pay for itself as opposed to a building that may not collapse, but has to be torn down and rebuilt due to extensive damage.

[constantinosschinas]

The problem is that you can use base isolation only in isolated buildings. If you have other building sharing a blind wall, it is not feasible. In Athens, Greece that this is the case, we have a minimum of 10cm gap between buildings, to allow for some movement.

Japan...ONLY Japan, this Country is so blessed with geniuses and contribute their knowledge for the betterment of their Society. Good for them.

Oh god! The video of the Hospital without isolation is terrifying! I cant imagine what people that lived thru such scenarios felt at the time!

Base Isolation like the type shown is a must-have in Earthquake regions, this needs to be factored into the pricing of buildings to ensure human life is protected.

Hospitals charge so much money, they can totally afford this technology.

Its also applied new hospitals in Turkiye but for old ones, danger still continues.

My eternal question with rubber dampeners is, rubber isn't forever; it dries up, it cracks, it even decomposes into ooze. What happens to the main structure once the dampeners begin to fail

Excellent videos well done,
Very well info,

[ProjectILT]

most places on earth: "7.0 earthquake, half our city collapsed."
japan: "20 billion magnitude earthquake, a bit of green tea spilled out of the cup"

[aleksandersuur]

What makes base isolation expensive? Certainly the lead-rubber bearings themselves are a marginal cost, right? The engineering effort to verify the solution maybe, is that where the cost is?

[Akira-grrd]

I'm glad this hospital didn't die!

[RMJ]

It pays to be prepared, which ironically is also always cheaper in the long run.

Reminds me of the Portal 2 intermediate access zone, between the salt mines and the upper facility, an endless plane of spring supports.

[fibonaccisrazor]

Wow, this is simply awesome. With this technology 30 or more thousand lives could have been saved in Turkey/Syria.

There shouldn't be a funding problem if governments were to do their calculations properly. 1 - What is the extra cost as a percentage of the total project, especially on high-rise or multistory buildings? 2 - Off balance this with the cost of rebuilding an entire city after a huge quake.

Surely it's way cheaper to build earthquake-proof.

I just did a school project on this, it worked best in the class. Amazing system, really.

[airliner]

If someone nears live in a quake-prone place, and they refuse to prepare their buildings for one, wait till something happens. They'll change their tune then.

Base isolation is expensive, but repairing the damage and lawsuits are more expensive
