Abstract:
Existing buildings reforms should include quality parameters and in timber-frame building systems the
vibration transmission should be well studied to comply with the acoustic requirements. The input
parameters for the prediction of vibrational response of floors can influence the results in modelled
building systems. In building structures, the analysis of radiation due to beam vibrations may be
represented from the wave propagation relationships as a one-dimensional system, a two-dimensional
system or a three-dimensional solid. Recent research indicates that for point connection, a beam is
usually modelled as a one-directional element. However, for lightweight structures such modelling type
does not show good correlation with experimental results. This study focuses on the differences that can
be obtain in the vibrational response due to an impact source exerted on typical timber-frame floors. It
also presents some examples for some modelling options for plate/beam systems with and without
ceiling, considering different connection types.
