Researchers place a model hospital on a shake table to assess the structure’s ability to withstand earthquake; in accordance with California latest building code, base isolators, which are rubber bearings intended to absorb the shock of the motion, were installed underneath the structure; the hospital passed the 6.7-magnitude and 8.8-magnitude tests with flying colors.

Last Tuesday, engineers from the University of California, San Diego conducted an ambitious and successful earthquake simulation, with what some called “boring” results.

Engineered had constructed a 5-story building, complete with a hospital operating room, an elevator, a kitchen filled with glassware. They also added a heavy air-conditioning unit to the roof. The building, built to California’s top earthquake codes, was then placed on top of a shake table, a device for shaking structural models or building components with a wide range of simulated ground motions, including reproductions of recorded earthquake time-histories.
