Braced Wall Panel (R602.10.1) – A braced wall panel is a section of a braced wall line that is. braced with a code-compliant bracing method (e.g., let-in brace, a wood structural panel, or. other bracing methods) (See Figure 4).
What does it mean to brace a wall?
Wall bracing is used to protect life by minimizing structural damage to a building in freak storms and earthquakes. All buildings are required to have some form of lateral bracing. Exterior and interior wall coverings are usually used with conventional light-frame construction.
Where will braced wall panels be placed?
A braced wall panel shall be located at each end of the braced wall line and at the corners of intersecting braced wall lines or shall begin within the maximum distance from the end of the braced wall line in accordance with Table 2308.6.
What is the difference between a shear wall and a braced wall?
In this guide, the term “shear wall” refers to an engineered wall segment designed in accordance with the IBC or referenced standards, and “braced wall” or “braced wall panel” refers to a wall segment constructed in accordance with the prescriptive bracing provisions of the IRC.How is a braced wall panel attached to the foundation?
Braced wall panel joints shall occur over studs or blocking. Braced wall panels shall be fastened to studs, top and bottom plates and at panel edges. Braced wall panels shall be applied to nominal 2-inch-wide [actual 11/2-inch (38 mm)] or larger stud framing.
Why is bracing important?
A bracing system is a secondary but essential part of a bridge structure. A bracing system serves to stabilize the main girders during construction, to contribute to the distribution of load effects and to provide restraint to compression flanges or chords where they would otherwise be free to buckle laterally.
What is the minimum length of a braced wall panel?
Braced wall panel length shall be a minimum of 24 inches (610 mm) and braced wall panel height shall be a maximum of 10 feet (3048 mm).
What does CS WSP mean?
Braced wall panel lengths for structures that are Continuous Sheathed Wood Structural Panels (CS-WSP) or. Continuous Sheathed Structural Fiber Board Panels (CS-WSP)What is a brace board?
OSB Braceboard is a high quality, moisture resistant structural bracing panel for timber framed construction that resists splitting and delamination. Made of 100% fresh pinewood thinnings from PEFC®/FSC® certified sustainable forests.
What are two types of structural bracing for a stud wall?Structural wall bracing is purpose-fitted bracing, being either sheet or cross-timber or steel bracing.
Article first time published onWhat is an alternate braced wall?
The alternate braced-wall-panel requires a continuous foundation across the length of the braced-wall line that is reinforced with a minimum of one #4 rebar top and bottom.
What is the purpose of cross bracing?
Cross bracing between joists or rafters strengthens the members by preventing sideways deflection. This bracing is known by many names such as herringbone strutting, blocking, bridging, and dwanging.
What are bracing lines?
Bracing lines are imaginary lines running along or across the full length or width of a timber-framed building. They have no physical significance but are required to control the positioning of bracing elements.
What are crawl space cripple walls?
Wooden floors and stud walls are sometimes built on top of an exterior foundation to support a house and create a crawl space. These are called cripple walls and they carry the weight of the house. During an earthquake, these walls can collapse if they are not braced to resist horizontal movement.
What kind of support does plywood wall bracing provide?
Why Plywood Bracing “Permanent bracing shall be provided to enable the roof, wall and floor framework to resist horizontal forces (racking forces) applied to the building. Appropriate connection shall also be provided to transfer these forces through the framework and sub-floor structure to the building’s foundation.”
What is wood structural panel?
WOOD STRUCTURAL USE PANELS. —Sheathing for Roofs, Floors, and Walls. Plywood and oriented strand board (OSB) are two types of wood structural panels commonly used in resi- dential construction.
Why are braces temporarily nailed prior to erecting wall frames?
The purpose of temporary bracing is to hold trusses straight and plumb prior to fixing permanent bracing.
How do bracings work?
Bracing members connect to separate points on the horizontal beams. This is so the ‘link’ between the bracing members absorbs energy from seismic activity through plastic deformation. Eccentric single diagonals can also be used to brace a frame.
What is brace in construction?
What Is Bracing in Construction? Bracing is a construction technique used to improve the structural performance of a building. Bracing systems include wood or steel components that help evenly distribute loads and increase the safety of the structure.
What does braced himself mean?

What is OSB in Australia?
OSB (oriented strand board) is the most used structural board for bracing, flooring and sheeting in timber frame buildings in many parts of the world. Perhaps it has been surprising that OSB is not been more commonly used in building and construction in Australia.
What is a WSP panel?
Exterior (WSP) Align vertical joints over studs. 1-1/2” blocking at horizontal joints. Extend sheathing to foundation sill plate. Exterior braced wall lines shall have a braced wall panel located at each end of the wall line.
What is a portal wall?
In a portal frame, the header extends past the opening and is tied to its wall with overlapping plywood or OSB to stiffen the joint. The panels are attached to the wall studs and to the header with closely spaced nails, and the sill is bolted to the foundation.

What are the type of bracing?
There are 5 main types of braces available today: Metal braces. Ceramic braces. Self-ligating braces. Lingual braces.
How do I stop wall racks?
To prevent racking, you can install diagonal let in bracing at the corners which was most commonly used in balloon frame construction. In modern platform framing, the exterior sheathing, if properly installed at the corners, will be sufficient to prevent racking.
What is lateral bracing?
Stabilizing a wall beam or structural system against lateral forces by means of diagonal or cross bracing either horizontally by roof or floor construction or vertically by pilasters, columns or cross walls.
What does continuous sheathing mean?
Continuous sheathing methods require structural panel sheathing to be used on all sheathable surfaces on one side of a braced wall line including areas above and below openings and gable end walls and shall meet the requirements of Section R602.
What is horizontal bracing?
Horizontal bracing is employed to resist horizontal / lateral loads on the structure and distribute them to the outer columns and thereby into the vertical stabilizing system. Horizontal bracing will also maintain the planar integrity of the structure and prevent it from deforming out of shape.
Why is diagonal bracing prohibited on center posts?
Diagonal bracing can contribute to the stiffness of the deck and, therefore, cause additional lateral loads on the posts. Since center posts receive more vertical load than corner posts, additional lateral load can cause overstress. For this reason, DCA 6 does not show the use of diagonal bracing on center posts.
What is a bracing element?
In the simplest terms, a bracing element is the portion of a building structure that provides stability for the framing. In other words, bracing elements help stop movement. To paint a visual picture for you, we’ll use the example of the standard base connection in Robertson’s metal structures–the “Pinned Base”.
