Abstract
The DOREAN design system is based on a wood structure made with girder trusses. This paper quantifies the contribution of the OSB panels on the load carrying capacity of the trusses in the DOREAN house structure. On the one hand, by experimental tests carried out on double shear specimens, and on the other hand by modelling a T-beam including the stiffness of the assembly between the panel and the truss beam. The connexion between the OSB panel and the upper chord of the lattice beam is realized by staples. Shear tests are performed varying the number of fasteners with three thicknesses of panel and three different orientations of the staples. This last parameter is of high importance because of the short loaded edge distance in the narrow wood element of the chords. Strength and stiffness of the stapled joint are obtained from tests and the interaction between fasteners is analysed. The T-beam obtained by the connexion between the OSB panels and the DOREAN lattice beam is modelled using beam elements. The semi-rigid behaviour is taken into account for all the connexions between the lattice beam elements and the OSB panels. Conditions of serviceability and ultimate strength are analysed with the influence of the variability of the T-beam parameters.
