• Steel columns are designed under compression, tension or combined loading depending on the loading conditions.

  • After the analysis, appropriate controls are made and reported according to the internal force situation.

Design Members for Compression

  • There are 2 main types of buckling, local and global buckling, in the elements under compressive force.

Local Buckling

  • Local buckling occurs when some part or parts of the cross-section of a column are very slender that they buckle locally in compression.

  • Limit values ​​for the classification of cross-sections for the local buckling boundary condition are given in Regulation 5.4 and Table 5.1A for cross-sections under compression force.

Global Buckling

  • Elements under the effect of compression may not function as an ideal compression element due to various reasons, although the bending moment does not occur as a result of these loads. The most important reasons are:

-Initial Curvature

-Load eccentricity

-Residual Stresses

  • Global buckling is divided into 3 categories: Flexural buckling, Torsional buckling and Flexural-Torsional buckling.
