H1. Combined forces (Beams: AISC 360)

Members subject to axial tension or compression and flexure about one or both axes are assessed in accordance with Section H1.

Plated beams only

For built-up (plated) beams a Proportioning Limit check applies. In AISC 360-05 and 360-10 this is detailed within the chapter on design for flexure (section F13.2). Load combinations which result in major axis bending on a built-up (plated) beam cause this check to be made. Any load combination which fails the Proportioning Limit check is considered as Beyond Scope for Combined Forces (regardless of whether any axial force is compressive or tensile).
