UPDATED SHEAR WALL DESIGN TOOLS

Force Transfer Around Openings (FTAO)

APA’s Force Transfer Around Openings (FTAO) Calculator, an Excel-based tool, and its explanatory Technical Note have just been updated for 2022. These tools are intended to help engineers and code officials in the design and implementation of FTAO shear walls.

Why FTAO instead of other shear wall methods? For one, FTAO offers more versatility, because it allows for the use of narrower wall segments while meeting required height-to-width ratios. For another, it's likely that fewer hold-downs will be required.
