Pr = required axial strength determined using LRFD or ASD load combinations, kips (N)
Pc = available axial strength, kips (N)
Mr = required flexural strength, determined using LRFD or ASD load combinations, kip-in. (N-mm)
Mc = available flexural strength, kip- in. (N-mm)

Design for Axial Force and Flexural Moment

  • The strength calculation considers 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.
