Abstract

Timber buildings are intrinsically lightweight and hence can be susceptible to low-frequency vibrations and structure-borne noise. So, within the development of technical solutions for mitigating unwanted vibrations and noise, accurate and computationally efficient numerical models are considered to be of great value. Such models should take into account all physical phenomena that are relevant for achieving adequate accuracy in predictions, while not being overly detailed so that the computational efficiency is impaired. In this paper, the necessity of modelling the enclosed air in room volumes of buildings made of cross-laminated timber, with respect to the prediction of vibration transmission, is investigated.

Timber buildings are intrinsically lightweight and hence can be susceptible to low-frequency vibrations and structure-borne noise. So, within the development of technical solutions for mitigating unwanted vibrations and noise, accurate and computationally efficient numerical models are considered to be of great value. Such models should take into account all physical phenomena that are relevant for achieving adequate accuracy in predictions, while not being overly detailed so that the computational efficiency is impaired. In this paper, the necessity of modelling the enclosed air in room volumes of buildings made of cross-laminated timber, with respect to the prediction of vibration transmission, is investigated. Coupled structural-acoustic finite element analysis is employed for an example building structure. It is found that modelling the air in the receiver room, i.e. in the room where the vibration response is evaluated, has a marked effect on the vibration transmission between panels.
