Abstract

An engineering method is presented for the analysis of creep deformation in wood due to changing moisture content. The method is applied to the analysis of stresses in timber during long-term loading. It is concluded that the larger variation of moisture content at the surface layer of timber makes its creep rate higher than in the middle of the cross-section. As a result, an increasing portion of the load will be carried by the inner part of the material during sustained loading. This uneven stress distribution may explain to a great extent why the strength of woo
