COST-EFFECTIVENESS OF VIBRATION CRITERIA FOR WOODEN FLOORS

The vibration serviceability requirements for wooden floors in accordance with Eurocode-5 (EC-5) as illustrated by Ohlsson [1] are rated using a combination of Value Analysis (VA) and the Checking Point Method (CPM) of the First-Order Reliability Procedure (FORP). The implied safety indices for the current requirements were first estimated and consequently the associated potential losses were deduced for varying design inputs considered as random variables with practical probability distributions. The preliminary results indicate the direction for enhancing the effective use of timber in flooring systems to withstand human-induced vibrations safely and economically.
