Serviceability Vibration Evaluation of Long Floor Slabs
Recently published AISC guidelines allow comprehensive evaluation of dynamic floor response in multiple bending modes, and provide a significant improvement over the heel drop procedures which they supercede. Vibration transmission is a phenomenon identified as potentially problematic, but not explicitly addressed. This phenomenon arises when a long floor slab exists, free of irregularities or openings, and the framing system is regular. Floor vibrations can then be transmitted perpendicular to the supporting members, causing unacceptable vibration serviceability behavior. This paper presents a preliminary analysis of this problem, modeling the long floor slab and framing system as a beam on a visco-elastic foundation. Examination of the response of the "Winkler beam" model yields a first estimate of floor accelerations caused by walking. The beam model is then used to evaluate the response to walking excitation of a floor in the Seattle-Tacoma International Airport.
