Equation B3-2

Design shall be performed in accordance with Equation B3-2:

RaRnΩR_{a} \leq \frac{R_{n}}{\Omega}

where

Ra= required strength using ASD load combinations Rn= nominal strength Ω= safety factor Rn/Ω= allowable strength \begin{aligned} R_{a} & =\text { required strength using ASD load combinations } \\ R_{n} & =\text { nominal strength } \\ \Omega & =\text { safety factor } \\ R_{n} / \Omega & =\text { allowable strength }\end{aligned}
