AbstractCriteria derived originally for walking vibrations in long- span steel joist floors with concrete deck are applied, with some adjustments, to long-span concrete floors. Field studies of two precast and one cast-in-place floor system are used to verify criteria and to estimate vibration parameters. Because of its relatively large mass and inherent stiffness to short-term load, cast-in-place construction generally is not prone to unsatisfactory vibration for normal human occupancy. The trend toward longer spans, less damping and thinner sections could result in problems if special care is not taken in the design. Also longer spans with lower frequencies can result in serious resonance problems in occupancies where repeated human activities such as dancing, clapping or stomping can occur.
