WebBrick and concrete buildings have low ductility and therefore absorb very little energy. This makes them especially vulnerable in even minor earthquakes. Buildings constructed of steel-reinforced concrete, on the other hand, perform much better because the embedded steel increases the ductility of the material. WebAnother tried-and-true technology to help buildings stand up to earthquakes takes its cue from the auto industry.
