Bracing is most eficient when placed at angles between 30° and 60°. With steeper bevels, the end connections can be cumbersome. Any brace configuration can be used to make up a horizontal bracing system, as long as a complete load path is available to transfer the load into the lateral load resisting system.
14 mar 2013 · Design of WT Braces. In most commercial buildings, floorand roof diaphragms are used to distribute loads in the horizontal plane of the structure to the lateral load resisting system.
This section covers roof bracing, wall bracing, floor and subfloor bracing. Figure 5.1 shows bracing examples for roofs, walls and subfloors. It should be noted that the wind force on unclad frames can be substantial and should be considered in the bracing design.
The Wall-Bracing-Length Calculator is a quick and easy tool to help calculate the required length of wall bracing per the 2009, 2012, 2015, 2018, 2021 or 2024 International Residential Code.
Bracing elements to resist wind are placed in line with the ridge and wind direction (see Figure 2). 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).
In a braced frame building, the resistance to horizontal forces is provided by two orthogonal bracing systems: Vertical bracing. Bracing in vertical planes (between lines of columns) provides load paths to transfer horizontal forces to ground level and provide lateral stability. Horizontal bracing.
Roof bracing WE COMPLETE THIS FOUR-PART BUILD SERIES ON CALCULATING BRACING REQUIREMENTS BY LOOKING AT ROOF BRACING.
