W Steel Beams - Allowable Uniform Loads

Example - Converting Moment of Inertia from cm⁴ to mm⁴

The I_x Moment of Inertia of beam W 12 x 12 x 230 is 100510 cm⁴. It can be converted to mm⁴ by multiplying with 10⁴ as

(100510 cm⁴) (10⁴ mm⁴/cm⁴) = 1005100000 mm⁴

= 1005 10⁶ mm⁴

The standard method for specifying the dimensions of a American Wide Flange Beam is for example W 310 x 250 x 79, which is 310 mm deep, 250 mm wide and with a weight of 79 kg/m.

I-shaped cross-section beams:

Britain : Universal Beams (UB) and Universal Columns (UC)
Europe : IPE. HE. HL. HD and other sections
US : Wide Flange (WF) and H sections
