Modelling guidelines for simulating low frequency vibroacoustic performance in wooden T-junctions

Abstract

Efficient and accurate numerical tools for predicting the vibroacoustic behaviour of wooden multi-storey buildings are lacking nowadays. The variability that a natural material as wood possesses, makes it difficult to accurately predict and model its behaviour. Likewise, construction details such as junctions and connections between structural elements play an important role in the dynamic response of wood structures. Modelling the exact geometry of any junction is practically impossible when performing finite element simulations as the size of the models would drastically increase to the point of exceeding computer capacity. Therefore, gaining knowledge into the behaviour of these structures as well as to find simplified ways of... (More)

Efficient and accurate numerical tools for predicting the vibroacoustic behaviour of wooden multi-storey buildings are lacking nowadays. The variability that a natural material as wood possesses, makes it difficult to accurately predict and model its behaviour. Likewise, construction details such as junctions and connections between structural elements play an important role in the dynamic response of wood structures. Modelling the exact geometry of any junction is practically impossible when performing finite element simulations as the size of the models would drastically increase to the point of exceeding computer capacity. Therefore, gaining knowledge into the behaviour of these structures as well as to find simplified ways of accurately modelling them is of paramount importance. In this paper, guidelines on how to model wooden T-junctions, commonly found in lightweight timber floors, are presented.
