Abstract

Abstract: It is demonstrated in this paper that the influence of moisture- and load variations on lifetime and residual strength (re-cycle strength) of wood can be considered by theories previously developed by the author. The common, controlling factor is creep, which can be modified very easily by introducing a special moisture dependent relaxation time in the well-known Power-Law creep expression. Because basic failure mechanisms in wood are invariant with respect to loading modes, it is suggested that a number of methods used in design of wood structures can be generalized/simplified to apply irrespective of loading modes and moisture conditions. Reliability studies may become more ‘reliable’ as the result of recognizing property distributions to be related. Keywords: Moisture variation, load variation, Power-Law creep, lifetime, fatigue, residual strength (re-cycle strength).
