APA - The Engineered Wood Association has developed a free on-line Wall Bracing Calculator that determines the code required amount of wall bracing in compliance with Section R602.10 of the 2009 IRC or 2012 IRC (International Residential Code). It is applicable for wind or seismic loads and has an intuitive graphical method of inputting walls (wall lines) and wall segments (braced segment or window/door opening). The final project can be printed or saved as a PDF.
Registration with APA is required and there is a Quick Start Guide available to explain additional details on the program.
