Reflection and transmission properties of wooden wall/floor building elements

Abstract

Various modal methods are frequently used to investigate the vibration pattern in construction elements of a building in the low frequency range. The experimental determination of time average transmission and reflection coefficient has been developed for the large scale building structures. In this study, we investigate a mock up of a wall/floor junction. The wave approach is combined with the continuity equation. In this fashion both the flexural wave propagation and the in-plane wave motion can be captured. The miss-match impedance was also an important factor, since there is a change of material in the junction. The goal of using scattering matrix formulation is to separate the transmitted wave and the reflected wave as the... (More)

Various modal methods are frequently used to investigate the vibration pattern in construction elements of a building in the low frequency range. The experimental determination of time average transmission and reflection coefficient has been developed for the large scale building structures. In this study, we investigate a mock up of a wall/floor junction. The wave approach is combined with the continuity equation. In this fashion both the flexural wave propagation and the in-plane wave motion can be captured. The miss-match impedance was also an important factor, since there is a change of material in the junction. The goal of using scattering matrix formulation is to separate the transmitted wave and the reflected wave as the structural wave propagates towards a wall/floor junction, but also to calculate the rate of wave conversion. One type of junction has been studied with the help of accelerometer matrices: the T junction of the floor/wall structure with its reinforcement beams.
