The Global Perception and Understanding of Vibration and Acoustics in Timber Structures

Abstract

Mass timber buildings are becoming more common globally, but challenges remain, particularly with timber’s performance when exposed to low-frequency vibration and acoustics. Timber’s lower density compared to concrete and steel results in lower natural frequencies comparatively that can be excited more easily by footfall induced events. If unmanaged, this could lead to occupant discomfort and at times structural issues. However, it is not suggested that mass timber floors are non-conformant, instead the concern and drive behind the author’s research has been the overly conservative design practices that may be occurring as a result. This could lead to excessive material usage, and costly builds when proposing mass timber.

The aim of this study tour has then been to visit a series of practitioners related to mass timber panel production, designers/ builders of mass timber structures, and researchers focusing on the challenges related to mass timber floor vibration and acoustics.
