Steel Design per EN 1993-1-1
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.
