First Ever Seismic Test Conducted on CFS Building

At the University of California a group of engineers are analyzing a lightweight steel-frame structure that is six-story high. The building is tested on the biggest external seismic shake table in the world. The objective of the experiment is to determine how well cold-formed steel buildings are able to sustain fires and earthquakes that may occur. As of date the six-story structure is the largest of its kind to be subjected to a shake table test.
