Steel Design is explained in detail under this title.
Definitions
-
Steel columns are designed under compression, tension or combined effect 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 slender that they buckle locally in compression.
-
Limit values for the classification of cross-sections for the local buckling boundary condition are given in EN 1993-1-1 5.5.2 and Table 5.2 for cross-sections under compressive force.
Global Buckling
-
Elements under the effect of compression may not function as an ideal compression element due to various reasons, although the flexure moment does not occur as a result of 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.
