Photo: Keeping Buildings Upright During Quakes: A new structural system dissipates energy to replaceable fuses and pulls buildings back upright after violent earthquakes. Xiang Ma, Stanford University From Popular Science:
How exactly does one build an earthquake-proof building? If you answered "make sure the structure rocks completely off its foundation," you're actually in good company. A research team led by Stanford and the University of Illinois successfully tested a structural system that holds a building together through a magnitude-seven earthquake, and even pulls it back upright on its foundation when the quaking stops. The key: embracing the shaking, by limiting the damage to a few flexible, replaceable areas within the building's frame.
