This illustrative four-color guide was developed to help building designers, builders, building officials and others using the code in the application of the lateral bracing requirements of the 2006 International Residential Code. While bracing is just one of many important factors to consider when designing, performing plan review, building or inspecting a structure, it appears to be one of most common sources of confusion and misapplication. The authors identify and explain the key elements of bracing and demystify the prescriptive bracing provisions of the 2006 International Residential Code.
Topics covered include:
- Understanding the forces that act on a house.
- History of bracing and how it works.
- Bracing and its use in the 2006 International Residential Code.
- The physical limits under which bracing can be used.
- Bracing options available to the builder/designer.
- Determining how much bracing is required with adjustments and variations.
- Special considerations for bracing.
- Attachment details for bracing units.
- Pony and cripple walls.
- Whole house considerations.
The basic concepts, historical perspective, and the correct application of the 2006 International Residential Code bracing provisions are presented in a logical format incorporating appropriate examples, specific applications, and suggested solutions.
From the Preface
This illustrated guide was developed to help building officials, designers, and builders apply the bracing requirements of the 2006 International Residential Code (IRC). While lateral bracing is just one of many important factors to consider when designing, performing plan review, building and inspecting a wood frame structure, it appears to be one of most common sources of confusion and misapplication. To develop the contents of this publication, the authors worked closely with the International Code Council (ICC) staff to identify and explain the key elements of bracing and to demystify the prescriptive bracing provisions of the IRC.
The most basic concepts of forces acting on the building, the historical perspective and the correct application of the IRC bracing provisions have been presented in a logical format, often incorporating appropriate examples, specific applications and suggested solutions. The final chapter of the book is
dedicated to whole house applications where several residential building plans in various wind, snow and seismic regions have been analyzed for proper wall bracing application.
Other aspects of the structure that work in conjunction with bracing to form a safe building, such as diaphragms, wall cladding and inter-element connections are discussed briefly, when necessary, to enhance understanding of bracing.
The information contained in this book, though written to explain the prescriptive bracing provisions of the 2006 edition of the International Residential Code, can also be applied to those bracing provisions of the International Building Code (IBC) Section 2308 (Conventional Light Frame Construction) that are similar to the IRC. The underlying concepts and theory of bracing are identical, but the provisions have evolved differently in the two code documents.
The ultimate goal of this publication is to promote the accurate understanding and the correct application of the code, resulting in safer buildings and communities - a goal that the APA and ICC share.
