Abstract

The paper concerns the development of a modular parametric finite-element model that can be applied to the analysis of vibro-acoustic problems in relation to multistory lightweight structures. Floors and walls can be modelled as structural elements, or substructures may be utilised for each type of module. A numerical example shows how the model can be employed to analyse a building with typical wooden panels made of plates on stud or joist frames. Computation times of less than half a second are obtained for a single frequency with a discretisation that is valid up to at least 250 Hz.
