Abstract
AbstractOriented strand board (OSB) sheathing-to-wood framing connections, as typically used in light-frame shear walls, were experimentally examined in a novel biaxial test setup with respect to p...
Highlights
In light-frame wood structures, shear walls are typically composed of a wood frame, which is cladded by a sheathing material in order to be able to serve as structural element in the lateral bracing system of buildings
The sheathing-to-framing connection investigated in this study consisted of an 11-mm-thick oriented strand board (OSB/2, Kronoply, Lucerne, Switzerland), which was connected to a C24-graded Norway spruce wood frame with dimensions of 60 × 60 mm by an annular-ringed shank nail with a diameter of 2.5 mm (Gunnebo Fastening Systems AB, Gunnebo, Sweden); see Fig. 1
Full-field deformation measurements were used to check the relative displacement between the OSB sheathing and the wood frame, utot;ARAMIS, which might have been different from the prescribed machine displacements, utot;MTS, due to the inherent stiffness of the test setup
Summary
In light-frame wood structures, shear walls are typically composed of a wood frame, which is cladded by a sheathing material in order to be able to serve as structural element in the lateral bracing system of buildings. The in-plane load-deformation behavior of such shear walls is mainly determined by the properties of the laterally loaded connections between the sheathing and the wood framing (Gupta and Kuo 1987). Possible changes in the in-plane loaddeformation behavior caused by changes in the direction of the loading path must be well understood in order to account for them in structural models and to make conclusions about their effect on the global behavior of shear walls. This motivates an experimental study of path dependence of nailed sheathing-to-framing connections, which is presented in this contribution
