AD 433: Dynamic modulus of
concrete for floor vibration analysis
The purpose of this AD note is to provide advice
from which the natural frequency of the beam

the constituent materials of the concrete mix and
the parameters which affect the actual properties

duration of loading and whether the concrete is
