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.
