324 Safety Factors

The bracing design recommendations that will follow are based on ultimate strength. The loads on the members being braces are assumed to be factored. Since both strength and stiffness are essential requirements for adequate bracing, resistance factors for each are necessary. When using an LRFD approach, the required stiffness is divided by a resistance factor of f = 0.75 to obtain a conservative requirement. The design brace force is based on factored loads and compared to the factored design strength of the brace and its connections.
