Vibration reduction in cross-laminated timber panels by using integrated elastomer layers

Bohman, A. LU ; Andersson, L. LU ; Persson, K. LU and Persson, P. LU (2025) p.96-101
Abstract

Construction with timber is becoming increasingly popular, partially due to its environmental benefits in comparison to steel and concrete. This is especially true for cross-laminated timber (CLT) panels an engineered wood product consisting of stacked timber lamellae oriented perpendicu-larly to each other. CLT panels have high stiffness in comparison to its mass, which leads to a sensitivity to dynamic loads, such as footfall loading, and is thus prone to vibro-acoustic problems. Enhancing the design of these panels is therefore of importance in order to mitigate low-frequency vibrations and structure-borne noise. This study aims at numerically investigating the possibility of mitigating the vibration response of CLT panels by... (More)

Construction with timber is becoming increasingly popular, partially due to its environmental benefits in comparison to steel and concrete. This is especially true for cross-laminated timber (CLT) panels an engineered wood product consisting of stacked timber lamellae oriented perpendicu-larly to each other. CLT panels have high stiffness in comparison to its mass, which leads to a sensitivity to dynamic loads, such as footfall loading, and is thus prone to vibro-acoustic problems. Enhancing the design of these panels is therefore of importance in order to mitigate low-frequency vibrations and structure-borne noise. This study aims at numerically investigating the possibility of mitigating the vibration response of CLT panels by introducing elastomer layers in-between the timber layers, as well as by exchanging the timber material from the typical spruce to oak. Numerical simulations of the panels were performed by use of the finite element method. Frequency-dependent material properties were used for the elastomer layers. It was shown that by changing the wood species and integrating elastomer layers in CLT panels, the vibration response can be reduced in the frequency range 1-120 Hz.
