Rectangular Hollow Section Properties

Rectangular hollow sections thermo mechanically treated tmt steel can be described as new generation high strength steel having superior properties such as weldability strength ductility and tensility which meet the highest international quality standards.

Rectangular hollow section properties. Astm 1085 table chart hss hollow structural section square structural tube. Rectangular tube section formulas the following table lists the main formulas discussed in this article for the mechanical properties of the rectangular tube section also called rectangular hollow section or rhs. Each steel hollow section features a high.

The rectangular tube however typically features considerably higher radius since its section area is distributed at a distance from the centroid. This specification covers cold formed welded carbon steel hollow structural sections hss for welded or bolted construction. Differences between rectangular hollow sections rhs and square hollow sections shs in general the procedure for calculating the properties of square hollow sections shs is the same as for rectangular hollow sections rhs.

Circular hollow sections these are manufactured up to a maximum size of 300 mm nb. Effective section properties for sections subject to axial compression effective section properties for sections subject to bending about y y axis. Universal beams ub universal columns uc.

The thickness of these steel hollow sections vary from 2 mm to 10 mm depending on what application the tubes would service. Rectangular structural tube per. The section property data for rectangular and square saw hss are based upon outside corner radii equal to 3 6 times the design wall thickness for saw sections with 5 8 inch nominal wall thicknesses and 3 0 times the design wall thickness for saw sections with nominal wall thicknesses equal to 1 2 inch and 3 8 inch.

The rest of the text covers the more general case of rectangular hollow sections rhs. Effective section properties sections subject to bending about x x axis effective section properties sections subject to bending about y y axis. The equations for rectangular hollow sections rhs may also be used for square hollow sections shs by substituting h b.

Effective section properties sections subject to axial compression. Design aid table of design properties for rectangular hollow steel sections rhs including section dimensions cross section properties area a second moment of area i elastic modulus wel plastic modulus wpl strength properties elastic moment mel plastic moment mpl plastic shear vpl and buckling properties section class buckling curves. Rectangular hollow sections these are manufactured up to a maximum size of 300x200 mm.
