Design of Steel Members for Combined Forces

SYMBOLS

P_r: Required axial force resistance for YDKT or GKT load combinations

P_c: Strength of axial compressive force available according to Section 8

M_r: Required bending moment strength for YDKT or GKT load combinations

M_c: current bending moment strength according to Section 9

Design for Axial Force and Flexural Moment

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

• The superposition of the stresses is only applicable to similar stresses.

• The superposition rule does not apply to when stability losses occur.

Design with ÇYTHYE 2018

• Equation 11.1 is used for double and single symmetrical members under the combined effect of compression and biaxial flexural moment.
