What is braced wall line spacing?
What is braced wall line spacing?
Braced Wall Line Spacing (R602. 10.1. 1) – Braced wall line spacing establishes the amount of racking load that must be resisted by the two or more parallel braced wall lines in each plan direction (see Figure 1).
Do interior walls need bracing?
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.
What is a bracing wall?
Similar experiences with seismic activity have also helped us learn how to design and build structures to better withstand earthquake forces. When applied per building code requirements, prescriptive lateral wall bracing provisions help structures resist the lateral loads that result from wind and seismic events.
What is bracing in wall framing?
Wall bracing is one of the critical elements of a wood-framed structure, providing resistance to forces that act along the wall plane. In storm-prone coastal areas especially, braced walls help the whole house resist lateral wind forces. The higher those lateral wind loads are, the stronger the structure must be.
How do you calculate bracing units?
To calculate the required bracing units along the building, multiply W by the value in the right-hand ‘Along’ column in NZS 3604:2011 Table 5.5 (subfloor), 5.6 (upper or single-level walls) or 5.7 (lower of 2 storeys).
At what spacing does tiled roofing require studs?
All these are moveable, so are not ‘dead’ loads. At what spacing does tiled roofing require studs? The correct answer is B – Closer spacing than metal roofing. Tiles must be at 450 mm and metal roofing at 600 mm.
Where do you put your brace?
Bracing lines should accommodate bracing elements anywhere on the lines. Braced frames, a structural system in buildings subject to lateral loads, generally consist of structural steel, which works well for the requirements of tension and compression on these frames.
What is the maximum spacing for wall bracing?
All braced wall lines shall be indicated on the plan, and their spacing shall be a maximum of 60 feet in both the longitudinal and transverse directions in each story . Exterior walls parallel to braced wall lines and all interior walls used as bracing shall not be offset more than 4 feet from a braced wall line (Figure R602.10.1.1).
Can a portal frame be used for wall bracing?
Tim Healey In a house design where some main walls may have many openings, portal frames can be the key to providing code-compliant wall bracing.
When do you need a braced wall line?
Braced Wall Line(R602.10.1) – Walls that are braced to resist racking are known as braced wall lines. Essentially all exterior walls are considered to be braced wall lines and are required to be properly braced with braced wall panels. Although not always required, interior walls may also be used as braced wall lines.
What is the International Code for braced wall panels?
Braced Wall Panel: All exterior walls shall be braced in accordance with the International Residential Code Se ction 602.10. Braced wall lines are basic elements in conventional light frame-construction and shall consist of braced wall panels.
