Experiments were conducted to determine some of the material properties of OSB. Tests covered three in-plane board directions and the through thickness direction. Results showed that OSB is an orthotropic material with better material properties in the direction of strand orientation. OSB in tension behaves almost linearly up to failure, whilst in compression it exhibits plasticity. This plasticity needs to be taken into account in nonlinear finite element analysis in order to simulate the structural behaviour of OSB appropriately. An elasto-plastic constitutive model for OSB in compression was established, based on the statistics of test results. The model was used in the FE simulation of a load test on a compression specimen and a nonlinear buckling analysis of an OSB webbed timber I-beam. The close prediction of behaviour of both specimens was considered to act as validation of the proposed constitutive model.
