Researchers have successfully simulated a high magnitude earthquake on the largest building ever tested, and the structure survived.

First they "played" the Northridge earthquake on the simulator for five minutes before turning to the Chi-Chi earthquake, watching the building all throughout the process."The building moved around just like a tree in a windstorm," Pei said.UC San Diego, Jacobs School of Engineering "The rocking wall system basically consists of a solid wood wall panel anchored to the ground using steel cables or rods with large tension forces in them,” Pei said. “When exposed to lateral forces, the wood wall panels will rock back and forth -- which reduces earthquake impacts --- and then the steel rods will pull the building back to plumb once the earthquake passes.
