A new automated tool provides assistance in the design of force transfer around openings (FTAO).
The Engineered Wood Association developed the free tool that includes a calculator and Technical Note. The FTAO method of shear wall design provides structures with a more comprehensive lateral resistance design which otherwise omitted the sheathing around windows or other large openings, according to a news release by the association.
“The FTAO method used to be considered cumbersome and somewhat undefinable due to the lack of specificity in the design code,” said Jared S. Hensley, P.E., APA Engineered Wood Specialist. “Now we have a new tool that simplifies the structural design process and makes the FTAO method more approachable and more precise.”
The APA FTAO Calculator provides the required hold-down forces, tension strap forces, and wall sheathing capacity, and automatically completes the design check in the final step. It also provides shear wall deflection calculations for the 3- and 4-term deflection equation options.
