Floor Vibration Induced by Dance-Type Loads: Verification

This paper describes both experimental tests and numerical calculations which were performed to verify an ancdytical method of calculating floor vibrations induced by dance-type loads. The basic experimental set-up is described, and experiments which were undertaken to investigate the interaction between people and structures are discussed. To demonstrate the accuracy of the analytical load model, measured and calculated load time histories are compared. The response of a structure to dance-type
loads is then checked by comparing finite element and analytical solutions and by comparing experimental and analytical solutions. To emphasise the importance of choosing an appropriate load model when calculating response, examples of resonant response caused by the sixth multiple of the dance frequency are provided. Finally, comparisons are made with the results from similar work conducted at NRC, Canada.
