Vibration in timber floors to Eurocode 5

TRADA image

The sensitivity of human beings to vibration is quantified in the form of base curves in BS 6472:2008 and ISO 2631-2. These standards clarify that the human perception of vibration is dependent on the frequency of vibration under consideration, are highly subjective to each individual and are subject to a number of factors.

Despite the individuality of each case, vibration is identified as one of the four main criteria groups for consideration under Serviceability Limit States (SLS) design, with a emphasis being placed on vibration in floors.

Vibration in timber floors (Eurocode 5)
addresses the design of timber floors under the vibration aspects of Serviceability Limit State Design presented in Eurocode 5 (BS EN 1995-1-1:2004 and the relevant UK National Annex).
This document details the fundamental background of vibration and identifies vibration sources, structural responses and human perception levels. Also included is a design example illustration how the EC5 method might be applied to UK timber floors and a glossary of vibration terms found in EC1 and EC5.
