The Specifications for Aluminum Structures (2020) provides the standards that structural engineers follow for aluminum design. Included in these specifications are limit state equations that use strength properties to calculate a member’s initial yield, full yield, and rupture values. One limit state that the standards currently neglect is the torsional failure of solid bars. Torsion is the act of rotation caused by a twisting force, otherwise known as torque. Future installments of the specifications hope to include torsional yielding and rupture equations, so this study investigates the validity of these proposed equations.

Two different aluminum alloys were investigated for this …
