dc.description.abstractEnThis paper deals with the study of the LVL behaviour (Laminated Veneer Lumber) under cyclic torsion loading. This study is part of an approach to better design the wooden structures under extreme wind or earthquakes. Torsion tests were carried out on rectangular specimen, end fixed with possibility of sliding head to prevent warping. Before each cyclic test, each specimen is tested under a monotonous rotation in the elastic area: torsion angle limited to 15 °. A reference cyclic stress level is defined as the ratio of the maximum moment applied to the maximum moment reached during the initial monotonous test. The signal of cyclic loading is triangular at various levels and amplitudes; the frequency is fixed at 1 Hz. The experimental results are used to study the influence of stress level and load magnitude on the damage and on the lifetime. A Model based on the damage theory is proposed. These cyclic torsion tests performed on LVL are also compared to experiments realized on glulam.
