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. Length. 38 x 25 x 1.6. The design resistance of the cross-section for axial force, shear force, and bending moment are calculated in accordance with EN1993-1-1 §6.2. Steel Hollow Sections: Manufacturer and Distributor. In addition the rounding of the corners is defined by the outer rounding radius ro and the inner rounding radius ri. The geometric properties that define the cross-section are: height h, width b and wall thickness t. Steel Stores in Brookvale, Bathurst, Blacktown, Orange, Revesby 1300 233 266 The classification of the total cross-section is determined by the class of its most unfavorable compression part. For class 4 cross-sections the effective cross-section properties must be defined that take into account the reduced effective widths of the compression parts of the cross-section as specified in EN1993-1-1 §6.2.2.5. For elastic verification the yield criterion in EN1993-1-1 §6.2.1(5) is applied, i.e. Rectangular - RHS. This rectangular hollow section is generated in the wide array of both standards as well as sizes. The geometric quantities include the total area of the cross section A and the second moments of the area Iy and Iz about the major axis y-y and about the minor axis z-z respectively.
