28
29 Based on Eurocode 5 (EN 1995-1-1:2004), load-duration classes can be taken into account in the //Timber// //design//.
30
31 The load-duration classes are characterized by the effect of constant load acting for a certain period of time in the life of the structure. For a variable action the appropriate class shall be determined on the basis of an estimate of the typical variation of the load with time.
32
33 Actions shall be assigned to one of the load-duration classes given for strength and stiffness calculations.
