7. For wind classifications greater than N2, spacing shall be in accordance with Table 8.20 and Table 8.21 for the relevant wind classification, ceiling depth and roof pitch. NOTE: Ceiling depth is measured parallel to the wind direction being considered. 8.3.6.7 Spacing of bracing walls in single storey or upper storey of two storey Refer page 148 of 1684.2 (2006) NOTE: 8.3.6.6 Location and distribution of bracing Bracing shall be approximately evenly distributed and shall be provided in both directions (see Figure 8.5). Bracing shall initially be placed in external walls and where possible at the corners of the building.
