RHS – Rectangular Hollow Sections. where the following auxiliary quantities are defined in EN 10210-2 §A.3 and EN 10219-2 §B.3: hg,y = h / 2 - ro ⋅ (10 - 3π) / (12 - 3π) and hg,z = b / 2 - ro ⋅ (10 - 3π) / (12 - 3π), hξ,y = (h - 2t) / 2 - ri ⋅ (10 - 3π) / (12 - 3π) and hξ,z = (b - 2t) / 2 - ri ⋅ (10 - 3π) / (12 - 3π), Ig = [1/3 - π/16 - 1 / (3⋅(12 - 3π))]⋅ro4, Iξξ = [1/3 - π/16 - 1 / (3⋅(12 - 3π))]⋅ri4. The outer rounding radius ro and the inner rounding radius ri are specified as nominal values to be used in calculations in the standards and they are specified in the design standards EN 10210-2 §A.3 for hot finished structural hollow sections and EN 10219-2 §B.3 for cold formed structural hollow sections: For any thickness: ro = 1.5t and ri = 1.0t, For thickness t ≤ 6 mm: ro = 2.0t and ri = 1.0t, For thickness 6 mm > t ≤ 10 mm: ro = 2.5t and ri = 1.5t, For thickness t > 10 mm: ro = 3.0t and ri = 2.0t. Class 3: Elastic bending moment resistance develops but local buckling prevents the development of plastic resistance. 2,0. About 94% of these are steel pipes, 1% are stainless steel pipes. Popular applications include stairway railings and overhead bridge constructions. The classification of the total cross-section is determined by the class of its most unfavorable compression part. RHS steel is used for many fabrication and construction purposes. In the following equations the quantity h in EN 10210 and EN 10219 is denoted as h0: h0 = 2⋅[(b - t) + (h - t)] - 2⋅Rc⋅(4 - π). The specified values are good approximations for the case of thin walled rectangular hollow sections with rounded corners.

They correspond to the gross cross-section resistance reduced by the steel partial material safety factor for cross-section resistance γM0 that is specified in EN1993-1-1 §6.1 for buildings, or the relevant parts of EN1993 for other type of structures, and the National Annex. In general the overall element resistance is smaller and must be verified according to the relevant clauses of EN1993-1-1 Section 6. They are calculated by adding the contribution of the external boundary and then subtracting the contribution of the internal void where the rounding of the corners is properly taken into account: A = 2t⋅(b + h - 2t) - (4 - π)⋅(ro2 - ri2), Iy = b⋅h3 / 12 - (b - 2⋅t)⋅(h - 2t)3 / 12 - 4(Ig + Ag⋅hg,y2) + 4(Iξξ + Aξξ⋅hξ,y2), Iz = h⋅b3 / 12 - (h - 2⋅t)⋅(b - 2t)3 / 12 - 4(Ig + Ag⋅hg,z2) + 4(Iξξ + Aξξ⋅hξ,z2). 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.
