APA System Report: APA Simplified Wall Bracing Method

The Simplified Wall Bracing Method described in this report provides building officials, builders and designers with an approach and the supporting technical information to meet the requirements of the 2012 IRC Simplified Wall Bracing (Section R601.12). In the development of this report, the 2012 IRC Simplified Wall Bracing has been modified to increase its applicability to a greater percentage of home designs. To achieve broad applicability and acceptance, the system uses the most common type of wall sheathing, wood structural panels, based on their superior structural performance.

This latest version expands the minimum required bracing by increasing the basic wind speed to 100 mph or less and the Wind Exposure Category to be B or C. It also adds partial credits to 8-foot walls from the existing 9-foot only walls. Revised February 2013. (Form SR-102 - 12 pages)

Wood Sheathing Builds Business

Three residential builders cut callbacks, improve customer relations, and meet code requirements using wood structural panels. This publication describes how three builders in Idaho, Texas, and Ohio gained a competitive edge by fully sheathing the walls of their homes with plywood or OSB. The builders reported improved structural performance and fewer appearance-related callbacks. The testimonials from the builders are consistent with the findings of a recent study conducted by the National Association of Home Builders Research Center. The builders surveyed reported increased racking strength, superior shear resistance, better nailing substrate, and other performance advantages with wood structural panels, compared to other non-structural products.
