Abstract
The quantifications of deflection in wood shear walls and diaphragms commenced in the late 1940s to early 1950s. This interest arose from the need to determine the ability of wood-framed structures to withstand considerable damage resulting from too much deflection under lateral loads such as wind and seismic events. As our understanding of the lateral loading characteristics on wood buildings has evolved, previous studies have demonstrated that cyclic loading profoundly alters the behavior of wood building structures.
A prominent factor contributing to shear wall deflections is nail-slip. In the event of lateral loading, the nails securing the plywood sheathing and framing tend to slip out of their designated positions. This phenomenon may lead to a reduction in stiffness, consequently increasing deflections in wood shear walls and diaphragms. The influence of cyclic loading compounds the issue of nail-slip, amplifying the deflection of the structural elements. This research also explores the effects of various factors on nail-slip, including framing type, sheathing type, and sheathing thickness. By investigating these variables, the study plans to provide a thorough understanding of how different parameters impact nail-slip and subsequently influence the overall deflection.
Lastly, this study seeks to propose an alternative approach to nail-slip that considers the above-mentioned parameters, which current building codes do not account for. By incorporating framing type, sheathing type and sheathing thickness, this unique approach aims to provide a more accurate prediction of nail-slip behavior under various loading conditions.
