The only thing similar to a rule of thumb is contained in ACI 350 Section
2.9 - Impact, vibration, torque, and seismic loads (only 3 pages long).
There is Table 2.9.2(a) "Natural frequencies of beams" and Table 2.9.2(b)
"Recommended maximum structural deflection for given equipment operating
It is not highly sophisticated, but it will generally keep an engineer who
is not a dynamcist out of trouble.
