For the same overall dimensions and wall thickness, the section properties for square and rectangular hot-finished and cold-formed sections are different because the corner radii are different. Steel Hollow Sections are providing to be the most versatile and efficient form of structural steel for construction and mechanical applications. For typical Rectangular Hollow Sections (RHS) the geometric properties of the cross-section are defined in the following standards: EN 10210-2: Hot finished structural hollow sections of non-alloy and fine grain steels, EN 10219-2: Cold formed welded structural hollow sections of non-alloy and fine grain steels.

Square and rectangular hollow sections in bending are normally considered as separate plate elements with a variety of stress distributions and edge restraints, and hence the theory of plate buckling can be used to determine when local buckling may occur in each element. 0000007726 00000 n
The elastic section modulii Wel,y and Wel,z about the major axis y-y and the minor axis z-z respectively are calculated by dividing the second moment of the area Iy and Iz with the corresponding distance from the centroid to the most distant edge: The plastic section modulii Wpl,y and Wpl,z about the major axis y-y and the minor axis z-z respectively correspond to the maximum plastic bending moment when the axial force of the cross-section is zero and the stress profile is fully plastic. The classification of cross-sections is specified in EN1993-1-1 §5.5. It corresponds to the relevant plastic section modulus Wpl,y or Wpl,z, for bending about the major axis y-y or about the minor axis z-z respectively, multiplied by the steel yield stress fy: The plastic bending moment resistance is applicable for class 1 or 2 cross-sections.
