Transmissibility, in the context of Structural Dynamics
, can be defined as the ratio of the maximum force (
) on the floor as a result of the vibration of a machine to the maximum machine force (

Structural Dynamics
Structural dynamics is a subset of structural analysis which covers the behaviour of structures subjected to dynamic loading. Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subject to dynamic loading. Dynamic analysis can be used to find dynamic...
