Vibration in Mass Timber



Ensuring optimal floor performance, particularly in the realm of mass timber construction, remains a top priority, especially concerning vibration.

Despite advancements, the absence of comprehensive codes addressing this crucial aspect is notable.


Vibration, often perceived subjectively, requires thorough exploration. Fortunately, recent developments such as well-documented guides and the second generation of Eurocode prEC5 approach have bolstered our understanding, offering nuanced performance levels based on distinct criteria, including response factor "R" for subjective human perceptions.

At TimberXP, we advocate for a deeper analysis of vibration dynamics, particularly in timber constructions, as a means to drive cost savings and performance enhancements.

In a recent Australian project, optimizing floor thickness for multi-storey residential buildings proved pivotal. Rigorous footfall analysis yielded crucial RMS acceleration data, facilitating precise determination of response factor (R) compliance with prEC5 standards.

Relying solely on basic calculations or generic guidelines wouldn't achieve the same level of cost savings or performance optimization.

While various approaches exist to address vibration issues, the prevailing gap in this critical aspect could jeopardize project success.

Recognizing this, we're actively enhancing our internal tools in collaboration with industry partners to provide more robust solutions for our clients.

We invite anyone interested in further discussions or insights to reach out.
