In the criterion presented by Murray,
an acceptable steel floor system is predicted, with respect to
vibration levels due to walking excitation, if the dynamic criterion
below is met.
This criterion is applicable to offices
and residences with fundamental natural frequencies below 10 Hz.
Murray criterion:
D > 35Aoƒ + 2.5
where D = damping in floor system,
expressed as a percent of critical
Ao = maximum initial amplitude of the
floor system due to a heel-drop excitation, in
ƒ = first natural frequency of the
floor system, Hz
This criterion is only applicable for
the units specified. The reader is cautioned against using other
units.
