SYMBOLS

Pr: Required axial force resistance for LRFD or ASD load combinations

Pc: Strength of axial compressive force available according to Section E

Mr: Required bending moment strength for LRFD or ASD load combinations

Mc: current bending moment strength according to Section F


Design for Axial Force and Flexural Moment

  • The strength calculation is made by taking into account the combined stresses created in the elements under flexural and axial force.

  • The superposition of the stresses only applies to similar stresses.

  • The superposition rule does not apply to stability losses.

Design with AISC 360-16

  • Equation H1.1 is used for biaxial and single symmetry axis members under the influence of axial compression and flexural moment.
