Collapse of Steel Frame Buildings
In this Building Collapse video, Professor Paul Grant examines what buildings are susceptible to collapse in earthquakes. The total collapse of steel framed buildings appears to be an extremely rare event, even when larger earth quakes are involved. In the Kobe and Mexico City earthquakes, many such buildings were severely damaged, and some experienced partial collapse. A 21 story office building in Mexico City appears to be the only such structure that has suffered a collapsed described as total as a result of stress other than controlled demolition.
