In this paper a computational method for evaluating moisture induced stresses in timber connections is proposed. A 3D orthotropic-viscoelastic-mechanosorptive model for wood is implemented in the Umat subroutine of the FEM code Abaqus and a moisture-stress analysis is performed. Some dowel-type connections are computationally analyzed under sustained mechanical loads and natural humidity conditions.
