APA Wall Bracing Calculator

This tool is intended to simplify the design of residential structures that comply with 2009, 2012, and 2015 International Residential Code (IRC) wall bracing requirements. The easy-to-follow process automatically determines how much bracing is required, whether there is enough qualified bracing, and whether all the IRC placement rules have been met. Along with streamlining the calculations, it verifies compliance without the user having to sift through pages and pages of code. And it generates a printout of the project to bring to building code officials.
