Earthquake drill finds weaknesses in steel high-rises
|
Simulation of a massive Southern California quake suggests about 5 steel high-rise buildings would collapse. But many engineers say other buildings are riskier and should receive priority in retrofit plans. Modern steel buildings have long been considered among the most sturdy in the event of a major earthquake. But a model of a massive quake in Southern California has sparked debate among scientists and engineers over whether these structures are more vulnerable than previously thought.
