Checkerboard Floor Framing: Design Through Construction [N46]

Checkerboard floor framing, where beam spans alternate in adjacent bays, results in shallower, lighter girders, improved vibration performance, and allows for the use of double-angle connections between the infill beams and the girders without the need for special consideration for erection of the adjacent beams. The presentation will include the description of several medical facilities that have been designed using checkerboard framing as well as a discussion of erection considerations. Field vibration testing and recommendations for modifications of existing vibration procedures to accurately predict vibration response of checkerboard framing will also be presented.
