Artificial earthquakes could lead to safer, sturdier buildings

Earthquakes never occur when you need one, so structural engineers are shaking up a building themselves in the name of science and safety. Using massive moving platforms and an array of sensors and cameras, the researchers are trying to find out how well a two-story building made of cold-formed steel can stand up to a lab-generated Southern California quake.
