| Popis: |
Structural modifications to an existing multi-story building installed to increase the load bearing capacity of a floor resulted in a noticeable increase in floor vibration from treadmills used in a fitness room on the floor above. Results from vibration measurements were combined with a finite element analysis (FEA) model of the building dynamics to determine the dynamic force generated by the treadmills in use. The FEA model and the calculated dynamic force were used to evaluate the effectiveness of options for vibration isolating the treadmills to reduce vibration to acceptable levels in the occupied office below.Structural modifications to an existing multi-story building installed to increase the load bearing capacity of a floor resulted in a noticeable increase in floor vibration from treadmills used in a fitness room on the floor above.
