Confused by the new bracing code? The 2011 IRC included some fabulous new updates to the bracing code. Some of it is more restrictive and more work but other things such as 45° walls are now allowed. If you have need of a calculator, thank Simpson Strongtie. They recently added a tool on their website which calculates the percentage of braced wall needed. Check it out at http://www.strongtie.com/products/strongwall/wallbracing/intro.asp.
This is our new favorite tool! Istockhouseplans attempts to design homes that do not need engineering for bracing. While the new code makes that trickier to design homes for the entire country, it does give us an idea of what might be more common. If all that needs to be done is reduce two 3/0 windows down to 2/6, perfect!
