I BEAMS
An I-beam,
also known as H-beam, W-beam (for
"wide flange"), Universal Beam
(UB), Rolled Steel Joist (RSJ), or double-T
is a beam with an I- or H-shaped . The
horizontal elements of the "I" are
flanges, while the vertical element is the web.
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.
