Bracing is designed by a set procedure: determine the wind classification, the lateral wind pressure from the tables (by storey, side, width and pitch), the area of elevation for the worst wind direction (including any verandah to be enclosed, combining parts of complex shapes), and the racking force as area times pressure in both directions; bracing is then distributed roughly in proportion to the forces. Appendix F offers a conservative alternative procedure.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
