Wood Shear Walls with Corners
Although the majority of residential structures in the United States are built using conventional construction practices, current U.S. building codes fail to provide methods for structural analysis of the lateral force resisting system of traditional light-frame buildings. Instead, the building codes specify prescriptive provisions that are believed to meet or exceed the strength and serviceability criteria, but provide the designer with little guidance for understanding the performance of the structure. Development of simplified analytical methods that accurately model the response of conventional construction will promote efficient design and more clearly define performance criteria for alternative methods of residential construction. Shear walls are the primary part of the lateral force resisting system for light-frame buildings. Sheathing-to-frame connections, anchorage methods, aspect ratio of braced wall panels and braced wall line, and type and size of perforations are the major factors that govern the response of light-frame wood shear walls. Sheathing connections resist shear forces, whereas anchors resist uplift forces. The choice of the anchorage method affects the shear wall stiffness, capacity, and failure mode. The latter can further influence ductility and seismic resistance of the shear wall. This study was designed to provide empirical and analytical insights into the response of shear walls with corner framing and to determine the uplift load sharing mechanism between the adjacent walls.
