For design purposes, it is suggested that the following damping ratios should be used for estimating the response of low frequency composite floor systems: 1,1 % for completely bare floors […]
EK364
For structures that possess a sufficiently high frequency (greater than approximately 10 Hz), such that it is effectively tuned out of the main harmonic components of walking force, the response […]

For structures that possess a low frequency of between approximately 3 to 10 Hz, harmonic components of the walking force can coincide with the floor frequency causing resonant excitation; in […]
