The rules for bracing against wind pressures have gotten complicated. Way complicated. The 2006 IRC devoted a scant eight pages to wall bracing, and by 2009, that section of the code (R602.10) had ballooned to 30 pages. An effort to simplify the 2012 version still left Section R602.10 with 27 pages of wall bracing rules.

Those rules are limited in scope: The methods they prescribe are allowed only if the design wind speed is less than 110 mph and the building is three stories or less. For taller buildings or higher wind speeds, you'll need an engineer. But if you learn the ins and outs of the IRC wall bracing rules — complicated as they are — you should be able...
