Effects of Access Floor on Vibration
Effects of Access Floor on Vibration
(OP)
I am currently designing a 9-story tower that has 18" access floor on every elevated floor slab because of major electrical requirements. The structure type is composite steel framing. My question is when designing the structural for vibration per Design Guide #11, can you include some sort of reduction in the vibration of the slab (other than the increase in DL)? It seems logical that access floor would help to mitigate floor vibration, but I'm not sure if research has been done in the matter to produce quantifiable, usable results for calculations. Any help you can provide is greatly appreciated.

I would expect this to provide both additional damping and additional dead weight which will both reduce the vibration. The specifics of the damping I am not sure of.
