Expected Material Strength
According to AISC 341-16, to determine the nominal strength, Rn, for limit states within a member or a connection of a member from which the required strength is determined, the expected yield stress, RyFy, and the expected tensile strength, RtFu, are permitted to be used in lieu of Fy and Fu, respectively.
