Ef-fect of Lamination Anisotropy and Lay up in Glued Laminated Timber. The paper presents experimentally and theoretically approach to the effect of relative humidity and moisture to the durability of massive spruce and spruce laminated timber during to drying and wetting exposure. It is increased or decreased to reach equilibrium depends on the level of moisture in the timber. The important point that the EMC at a given rel-ative humidity is not constant. The EMC decreases with decreasing relative humidity, also, increases with the increasing relative humidity of the surrounding air at a constant temperature. Also, EMC varies with the kind and distribution of cell-wall constituents, different wood species, af-fected by temperature, between heartwood and sapwood, extractives, previous ex-posure history and mechanical stress. This is called equilibrium moisture content (EMC) which is approxi-mately proportional to the relative atmospheric humidity (RH). It loses water until it comes to an adequately low moisture content to be at equilibrium with the surrounding atmosphere. After the tree is felled, the green wood is exposed to atmospheric conditions. Wood in the living tree generally has a moisture content (MC) of 30% or greater. Material properties are affected by the hygro-scopicity of wood for example, the strength value decreases with increasing mois-ture content of wood.
