Shake tables are way more complex than I thought

I'm a bit worried about whether the shaking comes across on camera. If you can use a big screen, please do! It's almost impossible to be close enough to see the shaking AND static reference points AND to have enough movement that it shows up on camera. But the noise? The noise, at least, sells it for me.

7:30 the test starts

I had the opportunity to be part of the subsequent phases of testing of a reduced version (6-story) of this building as a PhD student in civil engineering. It is amazing to see, even for us, the engineers who designed the structure! Thanks to Koorosh and the NHERI@UCSD staff for ensuring these tests run as smoothly as shown in the video.

7:44 Really important to specify

5:45 I sort of imagined that Russian hydroelectric dam that had one of 5 or 6 turbines disintegrate…Everything got really wet really fast.

We can save music to disks and now earthquakes too, introducing the earthquake "speaker"

That pump system is incredible

7:54 I tell myself that every day

Brilliant, Tom, thank you. What a great explainer that guy was also.

I need to move in one of these

I can't believe the earthquake machine has shopping cart wheels

I love seeing the under stucture absolutely full of "screws", every centimeter of the plates are CLAMPED by them and you know it's necessary

I've worked on construction projects in dozens of office buildings over the years, and after having spent loads of time in loading docks, service corridors, and basements, I don't trust any building higher than about three stories.

Wow. I'd pay $100 to sit on the top floor with a cup of coffee . . on the 99th interation of the test. Thanks for this one, Tom.
