This method, described in IRC R602.10.6, IBC 2308.9.3.1, UBC2320.11.4, is the similar to Method 3 of the conventional braced wall provisions, however it allows for walls to be built as narrow as 2’-8” provided that holdowns, additional anchor bolts, and for two-story structures additional nails and sheathing are also installed. These wall segments can be used to replace any braced wall panel in the non-continuously or continuously sheathed method. Framing requirements vary for one- or two-story structures as described in the figure below.
