The conclusion of each test was met with a round of applause. Engineers gathered on May 9 to shake a 10-story mass timber building–the tallest full-scale building to be tested on an earthquake simulator. The test took place at the UC San Diego NSF-funded outdoor shake table, one of the two largest shake tables in the world.
