This 8 story mixed use apartment building occupies a site which extends 447 ft. along Schermerhorn Street in Brooklyn, New York. The project had various earlier design cycles, in which engineers attempted, with little success, to develop a cost effective structural design which could also be approved by Transit Authority Engineers (TA). Supported directly on top of the roof of an existing subway tunnel, the 1st floor was designed as a floating platform, much like a tabletop, that rests on a complex network of isolators. Not fully decoupled from seismic ground motions, the structure was anchored into a reaction block, requiring special torsion and deflection calculations, which included Model Analysis and Soil Structure interaction.
