World's largest earthquake shake test
(OP)
This video is truly awesome, and I use the word advisedly.

Timing has a lot to do with the outcome of a rain dance.






RE: World's largest earthquake shake test
The video brings back memories when we attached accelerometers to every joint on a steel frame rocket test stand (60x60x80) that carried about 175,000# of fuel while the gimbaling rocket engine went through a 4 minute test. All critical design loads went up and not down. We had access to an air frame design/analysis program and compared the current(at the time) AISC code/standards.
A great education.
Engineer and international traveler interested in construction techniques, problems and proper design.
RE: World's largest earthquake shake test
-how many tables in the world can also simultaneously produce vertical movements?
-that event seemed very short, but perhaps the magnitude of the event they were testing only may last 15 seconds?
-it seemed like relatively low magnitude until I saw the interior shot
-the structure seemed to perform well, but it was likely over engineered and built in a lab. But I am impressed by how well a 6-story wood frame structure was able to resist the event without any major damage (from what they showed)...

RE: World's largest earthquake shake test
I believe most seismic shake table tests don't last much more than 20 seconds.
It looks like they are recreating the Northridge earthquake, which was one of the major ones. I don't think the video does justice to it.
