Serviceability Criteria for the Dynamic Response of Timber Floors

Timber floors can be susceptible to human-induced vibration due to the low density of timber compared to other construction materials. Human-induced vibration is a complex problem due to many involved parameters. As in many dynamic systems, the response depends on the dynamic parameters and the excitation source. Therefore, more advanced assessment methods must consider suitable human-floor interaction models. The most straightforward classification is based on the dynamic response. The increasing use of timber in commercial and office buildings requires more complex analysis than in residential dwelling. Therefore, the timber research community has proposed specific procedures for low-frequency floors. The dynamic response of timber floors improves under a combination between timber and other materials with complementary properties. Timber composite floors are generally made of wood products coupled with concrete, steel, glass or other wood products through a continuous or discontinuous connection. This paper reviews the most recent findings and research trends on vibration issues related to timber floors.
