Abstract

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.

Zusammenfassung

Versuche zur Bestimmung einiger Materialeigenschaften von OSB wurden durchgeführt. Die Versuche umfassten Prüfungen in drei Richtungen der Plattenebene, sowie eine Prüfung quer zur Plattenebene. Die Ergebnisse zeigten, dass OSB ein orthotropes Material mit besseren Materialeigenschaften in Richtung der Spanorientierung ist, während es sich bei Zugbeanspruchung hingegen plastisch verformt. Dieses plastische Verhalten muss bei nicht-linearen Berechnungen berücksichtigt werden, um das Festigkeitsverhalten von OSB richtig zu simulieren. Auf Grundlage der statistischen Versuchsergebnisse wurde ein elasto-plastisches Modell für OSB unter Druckbeanspruchung entwickelt. Das Modell wurde für die FE-Simulation eines Druckversuches und eine nicht-lineare Knickberechnung eines I-Balkens mit OSB-Steg verwendet. Die gute Übereinstimmung der Ergebnisse in beiden Fällen bestätigte die Eignung des Modells.
