For some dwellings using the Simplified Method. There are three scenarios solved using the IRC Section R60212. A Guide Page 3 manner offsets can affect braced wall panel location and thus the layout of openings for windows and doors in a series of braced wall lines on a given building side elevation.

The presentation will provide a systematic overview of the various methods of compliance while focusing on commonly used structural panel and continuously sheathed options. The distance between adjacent braced wall panels cannot exceed 20 feet. Strong-Wall model numbers and foundation anchorage designs are determined to meet job specific requirements and provide the narrowest bracing solutions possible.

Prescriptive wall bracing provisions in the 2018 International Residential Code IRC. Bracing has to be planned during design and built into the structure during construction. APA The Engineered Wood Association.

The placement and amount of braced wall panels for each braced wall line are required to meet all four of the following rules. Also Appendix B demonstrates a simple and efficient engineering-based approach to application of the IRC bracing provisions by design professionals.
