Design tables for Structural Steel Sections (Eurocode 3, EN1993-1-1:2005)

Tables with all the international steel sections, with their dimensions, properties,   classification, resistance and buckling resistance values according to Eurocode 3, EN1993-1-1:2005. The tables are extended to welded section with dimensions given from the user.

Classification and resistance of standard steel sections

Classification of cross section according to EN1993-1-1:2005 §5.5.
Resistance values of cross section according to EN1993-1-1:2005 §6.2.
Buckling resistance and lateral buckling resistance according to EN1993-1-1:2005 §6.3

  • Classification (1,2,3,4) according to EN1993-1-1:2005 §5.5 for axial loading and loading with bending moments.
  • Resistances of the section in compression, bending in y-y and z-z axis, and shear according to EN1993-1-1:2005 §6.2 
  • Buckling resistance for various buckling lengths (Lc) according to EN1993-1-1:2005 §6.3.1 
  • Lateral torsional buckling resistance for various  lateral buckling lengths (Llt) according to EN1993-1-1:2005 §6.3.2

The design of steel elements can been done with elastic or plastic analysis depending on the class of the cross section.

The design of sections of classes 1 and 2 is based on the plastic resistance, the design of cross-sections of class 3 is base on elastic resistance and the design of cross-sections of class 4 is based on elastic resistance and effective cross section properties.

The classification of cross sections in 1, 2, 3 and 4 classes depends on the ratios of thickness to width of the parts of the cross-section which are in compression according to tables 5.2 of ΕΝ 1993-1-1:2005.
