Structural Serviceability: Floor Vibrations

Abstract

Floor vibrations arising from normal human activity may affect the serviceability of modern building structures, which are becoming lighter and more flexible. Existing serviceability criteria for floors are reviewed in the light of research dealing with human perception of structural motion. The dynamic response of floors to realistic pedestrian movement excitation models is analyzed. Tentative serviceability criteria to minimize floor vibrations that are objectionable to building occupants are presented.
