ABSTRACT ONLY:
New York City’s Department of Transportation is in the process of evaluating and, if necessary, rehabilitating its many important bridges to meet seismic guidelines. In a comprehensive two-part evaluation of the foundations of the Brooklyn Bridge that used the latest modeling techniques, engineers determined that the bridge’s foundations have the ability to withstand a 2,500-year event without any sliding or separation at their bases, obviating the need for retrofits that might alter the architectural form of the renowned crossing.
