    Abstract

    In this paper a numerical method for the evaluation of moisture induced stresses in timber structures is proposed. A multi-Fickian approach for the moisture transfer modelling is used. A moisture-stress analysis based on a 3D orthotropic-viscoelastic-mechanosorptive model for wood is performed by using the Abaqus FEM code. The constitutive model and the needed equations of moisture diffusion are implemented into some Abaqus user subroutines. The results, in terms of moisture content and stress, are compared with experimental data available in the literature for glulam beams subjected to moisture gradients.
