A plasticity based constitutive compressive material model is proposed to model wood as elasto-plastic orthotropic according to the Hill yield criterion in regions of bi-axial compression. Linear elastic orthotropic material response is applied otherwise with maximum stresses taken as failure criteria. The model is implemented in the finite element code to carry out the analysis of bolted connections using ADINA software. Reasonable agreement is found between numerical simulations and experimental measurements of local and global deformation of one-bolt connection. The predicted failure modes are consistent with experimental observations.
