Last summer, a six-story steel framed structure withstood multiple massive earthquakes and fires in San Diego. To recap the testing, researchers at UCSD Jacobs School of Engineering put a six-story lightweight cold formed steel building through a series of scaled motion earthquakes. The six-story building layout was designed to replicate a multi-family residential structure.
One of the main purposes of the tests was to see if it was even possible to withstand a historic earthquake combined with an ensuing fire in a multi-story, multi-family structure. The results of the tests, as outlined in this article from STRUCTURE Magazine, proved that cold-formed steel framing could not only withstand the earthquakes and fire but could also be built much more efficiently than traditional wood or concrete structures.
