Floor vibration

In the design of floor systems in buildings vibrations
caused by walking, dancing, mechanical equipment or other rhythmic excitation may cause an annoyance to the occupants or impede the function of sensitive equipment. A calculation procedure to analyze steel framed floor systems is given in a design guide published by the American Institute of Steel Construction.
Modern concrete under-floors often specify a 3mm layer of sound-deadening material above (is it foam plastic like ethaline - something with a long-life since it will be expensive to replace).
Oscillation
Oscillation is the repetitive variation, typically in time, of some measure about a central value or between two or more different states. Familiar examples include a swinging pendulum and AC power. The term vibration is sometimes used more narrowly to mean a mechanical oscillation but sometimes...
