The design criterion is intended to be used during the design of buildings with allowable design properties to ensure performance of the floors after construction. The criteria was developed using vibration. Are not covered by this design guide.
Preventing annoying wood floor vibration 1999 journal of structural engineering. The design and assessment methods for floor vibrations are related to human induced resonant vibrations mainly caused by walking under normal conditions. A new design criteria for preventing annoying vibration in wood floor construction has been presented. In theory joist designs or floor system designs that vibrate well above 7 10 hz should be judged by the occupants as acceptable simply because they can t feel the higher frequencies.
For transient vibration the method is based on determining the peak floor velocity response due to a unit impulse mm s n s and the product of damping coefficient and frequency. Pedestrian bridges or other structures which do not have a structural characteristic or a. General vibration design principles occupantsare very sensitive to vibrations in the range of 7 10 hz. This paper will evaluate six criteria proposed by other researchers in two different ways.

In recent years several dynamic design criteria have been proposed to address vibrational serviceability. First a design deflection factor will be determined based on specific floor dimensions and average material properties. The criteria requires that the fundamental frequency of the floor joists and combinations of joists and supporting girders be greater than 15 hz.View Video For Wood Floor Vibration Design Criteria
