2018 IRC Simplified Wall Bracing Provisions 2019 ICC Annual Conference Educational Sessions Handout Description This seminar provides a comprehensive explanation of the 2018 International Residential Code (IRC ) simplified wall bracing requirements. It guides the participant through an in-depth review and analysis of the bracing requirements for wood-framed residential structures. 2018 IRC Simplified Wall Bracing Provisions 4 Objectives Upon completion, participants will be better able to: 1. Identify the forces that act on a house. 2. Determine bracing materials available with simplified wall bracing. 3. Apply simplified wall bracing provisions. 4. Review connections required at floor and roof. 2018 IRC Simplified Wall Bracing Provisions 5 Resources www.iccsafe.org Item # 7102S18 2018 IRC Simplified Wall Bracing Provisions 6 2 Copyright 2019 International Code Council

2012 IRC Simplified Wall Bracing Provisions 4/28/2015 3 7 Goal Participants will successfully apply the provisions of Section R602.12 of the 2012 IRC to problems involving bracing requirements for wood-framed residential structures in their region. 2012 IRC Simplified Wall Bracing 8 Objectives Upon Completion of this webinar, you will be able to:
The guide is divided into six sections intended to supplement and enhance the 2009 IRC wall bracing provisions: Section 1: Basic Concepts for Code-Compliant Wall Bracing Section 2: Wall Bracing Methods Section 3: Applying the Code Section 4: „Beyond Code‟ Bracing Solutions Section 5: Wall Bracing Options for Foam-Sheathed Wall Systems .
Historically, proper wall bracing construction per the IRC required a minimum of 4-feet of available wall length. With design trends calling for larger window openings and narrow garage return walls, the wall space available for bracing has been limited. This bulletin outlines braced wall panel options for narrow wall segments (IRC R602.10).
