Vibration criteria for long-span floors

Annoyance criteria are derived for walking vibrations of long-span floors. The criteria are developed primarily for steel beam or joist construction with concrete deck, spans greater than about 25 ft (8 m) and natural frequencies less than about 10 Hz. The criteria are expressed in terms of the dynamic properties of a floor as measured by a heel impact test. The advantage of the heel impact test is that it provides a tool for design calculation.
