Introduction to Wall Bracing

Technical Guides

Wall bracing is one of the most important structural elements of a house. Bracing strengthens the frame to help keep walls square when experiencing strong lateral forces like high winds or earthquakes.

This publication is designed for: architects, engineers, builders

This publication provides an overview of meeting the 2018 International Residential Code (IRC) wall bracing requirements. Continuous sheathing with plywood or oriented strand board (OSB) is a simple solution to meeting the IRC wall bracing requirements. This method also allows bracing segments as narrow as 16 inches.

Key sections include:

  • Explanation of lateral forces

  • Defining “braced wall panels” and “braced wall lines”

  • Braced wall panel length

  • Discussion of corner windows and braced wall panels not at the end of braced wall lines

  • Determining the minimum length of bracing in a wall line using the 2018 IRC

  • Examples of permitted offsets in a braced wall line

  • Putting a well-braced home together
