Wood shearwalls are typically used in locations where increased lateral resistance is required, such as around window and door openings, on garage wing walls and interior walls. When designing a wood shearwall, Designers need to consider the shear (sheathing and nailing), overturning (holdowns), concrete anchorage and drift. Simpson Strong-Tie has developed a web application that can quickly design shearwalls based on demand load, wall geometry and shearwall design parameters.

Shearwalls can be designed per 2015 IBC.
Various bug fixes to improve application performance.
The Simpson Strong-Tie Site-Built Shearwall Designer web application was created to facilitate the design of Site-Built, Engineered, Wood Shearwalls. The web app performs a technical analysis that provides actual drift, uplift values and post compression for a wind or seismic lateral load.
The Strong-Wall analysis also considers simultaneous, vertically applied loads such as Dead, Live, Live Roof, Snow, Rain, Wind Uplift; acting in a uniform manner across the wall or as a series of point loads, or both. In addition, the Designer has the ability to account for other sources of Vertical Displacement due to Rod Elongation, Wood Shrinkage, or other.
The web application provides two options for generating an engineered solution, Solid Walls or Walls with Opening (FTAO). Both options generate solutions that offer different combinations of Sheathing/Nailing, Holdown Model, End Studs, and Number/Type of Shear Anchors. Once a solution has been selected the app will generate a pdf output. Files can be saved and reused for future designs.
