APA Force Transfer Around Openings Calculator
The force transfer around openings (FTAO) method of shear wall analysis offers some advantages compared to other methods:
- More versatility, because the FTAO method allows for the use of narrower wall segments while meeting required height-to-width ratios, and
- A high likelihood that fewer hold-downs will be required.
APA's FTAO calculator is an Excel-based tool for professional designers that uses FTAO methodology to calculate maximum hold-down force for uplift resistance, the required horizontal strap force for the tension straps above and below openings, the maximum shear force to determine sheathing attachment, and the maximum deflection of the wall system. Learn more and download the calculator on our FTAO page.
