John Jay College Expansion Project Structural Transfer Systems
This thesis is the culmination of a yearlong study performed on the John Jay College Expansion Project located in Manhattan. This academic building includes a midrise tower with classrooms, laboratories, and office spaces that reaches a maximum height of approximately 240 feet above 11th avenue. Amtrak tracks pass beneath the South-West corner of the site, which led to a unique structural system for the midrise tower. Floor framing is attached to hanging perimeter plates, which are then connected to cantilevered penthouse trusses. These trusses then transfer gravity loads to the building’s lateral force-resisting system, which is a braced frame core. This structural solution provided the John Jay College Expansion Project with some unique architectural features, however, it also introduces complex construction methods. This study focuses on a new transfer solution that is more constructible than the existing design, is more efficient than the existing design, and also displays this transfer solution as an architectural feature.
