Abstract

In lightweight buildings there can be problems due to heavy impacts, such as from footsteps in bare feet or children jumping. For this reason the standard rubber ball is used in measurement standards to assess heavy impacts. In this paper, experimental work on a mock-up timber floor is used to provide benchmark data to validate a model using Finite Element Methods (FEM) of the standard rubber ball exciting a timber floor. Experimental Modal Analysis was initially used to extract damping information and the Modal Assurance Criterion was used to confirm that the FEM model of the timber floor was reasonable. A FEM model was then used to predict the time-domain response of the timber floor when excited by a single impact from the standard rubber ball which was included in the FEM model. Comparison of these FEM predictions with experimental data was assessed using the Frequency Domain Assurance Criterion which indicated reasonable agreement with the experimental results.
