AbstractThe widespread belief that resonance vibrations in a structure can be avoided if its natural frequency is higher than the forcing frequency is not always correct. The following example of a gymnasium shows that with certain periodic impact forces (in this case running, hopping and jumping exercises for physical conditioning) lightly damped structures may be forced into significant resonant vibrations if their natural frequency falls on a integer multiple of the forcing frequency. Soon after the completion of a two-storey gymnasium considerable structural vibrations were noticed in the building. These occurred mainly when the upper gymnasium was used for conditioning exercises done to music e.g. running, hopping, and jumping.
