Equipment Foundation for Rotating Mass

Equipment Foundation for Rotating Mass

Equipment Foundation for Rotating Mass

(OP)
Hello,

I am trying to find information on how to estimate the unbalanced load from a mass imbalance in a piece of rotating equipment that sits on an elevation foundation. Excessive vibrations can be observed in the foundation element and we are investigating the possibility that the vibrations could be a result of a mass imbalance from the equipment resting on the foundation.

Does anyone have any insight into possibly estimating mass imbalance as a % weight of the rotating equipment?

Also, does anyone have any design examples of supporting rotating equipment on an elevated steel deck?

Any insight would be most appreciated.

Thanks!

RE: Equipment Foundation for Rotating Mass

Check out ACI 351.3R-10. It should have the information you are looking for.
