I beam

An I-beam, also known as H-beam (for universal column, UC), w-

beam (for "wide flange"),universal beam (UB), rolled steel joist (RSJ),

or double-T (especially in Polish, Bulgarian,Spanish, Italian and

German), is a beam with an I or H-shaped cross-section. The

horizontal elements of the "I" are known as flanges, while the

vertical element is termed the "web". I-beams are usually made of

structural steel and are used in construction and civil engineering.
The web resists shear forces, while the flanges resist most of the

bending moment experienced by the beam. Beam theory shows

that the I-shaped section is a very efficient form for carrying both

bending and shear loads in the plane of the web. On the other

hand, the cross-section has a reduced capacity in the transverse

direction, and is also inefficient in carrying torsion, for which hollow

structural sections are often preferred.
