## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IBC 2009, IRC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IBC 2009 Wood (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 7 (counted across the codes hosted here) |
| Wording identical across codes | No (compare before citing one code's wording under another) |

## Direct answer

Braced wall panel is a defined term in the International Building Code (IBC) 2009, in Wood. The code's own words are: “A section of wall braced in accordance with Section 2308.9.3 or 2308.12.4.” The IRC 2009 words it differently, in Definitions: “A full-height section of wall constructed to resist in-plane shear loads through interaction of framing members, sheathing material and anchors. The panel's length meets the requirements of its particular bracing method, and contributes toward the total amount of bracing required along its braced wall line …” The IRC 2009 defines the same term with different wording, so the controlling text depends on which code governs the question in front of you — the comparison below sets the versions side by side. The term is used in 7 chapters of this corpus, most often in Wall Construction (IRC 2009), Wood (IBC 2009), Building Planning (IRC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## What must be verified before using this guidance?

Two of the I-Codes in this corpus define **Braced Wall Panel**, and the wording is not identical — read the version that governs your question.

| Code | Where it is defined | Definition |
| --- | --- | --- |
| IBC 2009 | [Wood](https://harth.build/resources/building-codes/us-states/maryland/ibc-2009/wood.md) | A section of wall braced in accordance with Section 2308.9.3 or 2308.12.4. |
| IRC 2009 | [Definitions](https://harth.build/resources/building-codes/us-states/maryland/irc-2009/definitions.md) | A full-height section of wall constructed to resist in-plane shear loads through interaction of framing members, sheathing material and anchors. The panel's length meets the requirements of its particular bracing method, and contributes toward the total amount of bracing required along its braced wall line in accordance with Section R602.10.1. |

### The term in use

How the code actually writes about braced wall panel, quoted from the 2009 text hosted here:

> The length of bracing along each braced wall line shall be the greater of that required by the design wind speed and braced wall line spacing in accordance with Table R602.10.1.2(1) as adjusted by the factors in the footnotes or the Seismic Design Category and braced wall line length in accordance with Table R602.10.1.2(2) as adjusted by the factors in …

## The terms braced wall panel is built out of

The definition above leans on 2 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what braced wall panel covers:

- **[Braced Wall Line](https://harth.build/resources/glossary/braced-wall-line.md)** — IBC 2009: A series of braced wall panels in a single story that meets the requirements of Section 2308.3 or 2308.12.4.
- **[Loads](https://harth.build/resources/glossary/loads.md)** — IBC 2009: Forces or other actions that result from the weight of building materials, occupants and their possessions, environmental effects, differential movement and restrained dimensional changes.

## Frequently asked questions

### What is the code definition of braced wall panel?

The International Building Code (IBC) 2009 defines it in Wood as: “A section of wall braced in accordance with Section 2308.9.3 or 2308.12.4.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.

### Which parts of the code depend on braced wall panel?

In this corpus the term is used across 7 chapters, led by Wall Construction in the IRC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.

### What is a braced wall panel?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IBC 2009 states, in Wood: “A section of wall braced in accordance with Section 2308.9.3 or 2308.12.4.” It is defined in IBC 2009, IRC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.
