7.6 - Vibration
Back to main Contents page
The recommended minimum natural frequency for a composite floor plate (consisting of both the composite slab and composite beams) is 5Hz when used in office or domestic type applications. This limit should be increased to 8.4Hz for floors subjected to rhythmic activities such as gyms, dance studios or even plant areas supporting machinery.
Using SMD Elements® software, the dynamic deflection of the composite slab is calculated in accordance with SCI Publication P-354: Design of Floors for Vibration – A New Approach. Using the guidance and calculation method contained in P-354, this deflection can then be added to that for the composite beams enabling the Natural Frequency of the floor plate to be determined.
