An I-beam, also known as H-beam, 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.
The method of producing an I-beam, as rolled from a single piece of steel, was patented by Alphonse Halbou of the company Forges de la Providence in 1849.

The I-Beam was a popular nightclub in San Francisco that was located in the Haight-Ashbury neighborhood at 1748 Haight Street. Before opening the club, Sanford Kellman had an impromptu party there and found that all the neighbors complained about the noise. Therefore, Sanford Kellman was required by the City government of San Francisco to soundproof the entire building at great expense, delaying the opening of the club for several months. On the opening night of the club in October 1977, groups of bare-chested men in jeans and construction hats carried I-Beams on their shoulders into the club.
The I-Beam began as a seven night a week Gay Club in 1977, the second largest Gay Dance Club in San Francisco. The City Night Club also known as the Cabaret was the first large Gay Club in North Beach district. As the crowd left the I-Beam for the newer clubs South of Market such as The Trocadero and later on Dreamland, the I-Beam opened only for five days a week. Randy Schiller who built the new sound system for the club was operating a recording studio where he had a long list of bands recording in his studio decided that we should reopen on Monday nights which started "Monday Night Live." with local bands.
Beam may refer to:
In musical notation, a beam is a horizontal or diagonal line used to connect multiple consecutive notes (and occasionally rests) in order to indicate rhythmic grouping. Only eighth notes (quavers) or shorter can be beamed. The number of beams is equal to the number of flags that would be present on an un-beamed note.
The span of beams indicates the rhythmic grouping, usually determined by the time signature. Therefore, beams do not usually cross bar lines, or major sub-divisions of bars. If notes extend across these divisions, this is indicated with a tie.
In modern practice beams may span across rests in order to make rhythmic groups clearer.
In vocal music, beams were traditionally used only to connect notes sung to the same syllable. In modern practice it is more common to use standard beaming rules, while indicating multi-note syllables with slurs.
Notes joined by a beam usually have all the stems pointing in the same direction (up or down). The average pitch of the notes is used to determine the direction – if the average pitch is below the middle staff-line, the stems and beams usually go above the note head, otherwise they go below.
The beam of a ship is its width at the widest point as measured at the ship's nominal waterline. The beam is a bearing projected at right-angles from the fore and aft line, outwards from the widest part of ship. Beam may also be used to define the maximum width of a ship's hull, or maximum width plus superstructure overhangs.
Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at expense of reserve stability in the event of a capsize, where more energy is required to right the vessel from its inverted position.
Typical length-to-beam ratios for small sailboats are from 2:1 (dinghies to trailerable sailboats around 20 ft or 6 m) to 5:1 (racing sailboats over 30 ft or 10 m).
Large ships have widely varying beam ratios, some as large as 20:1.
Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a coracle has a ratio of almost 1:1 – it is nearly circular.
The beam of many monohull vessels can be calculated using the following formula:
Third time writing you a letter, getting darker. I’m getting worse and worse.
I had a reason for the writing, but trying to exorcise my demons didn’t work.
To try to rid me of The worry and to purge you out of wonder for the future and the hurt.
I wrote a poem:
I’m increasingly aware I’ve been painting things in gray,
I’m increasingly alarmed by the pain,
I’m increasingly alive to every cloud up in the sky,
I’m increasingly afraid it’s going to rain.
See, lately I’ve hated me for over-playing pain.
For always pointing fingers out at everyone
but Who in fact is guilty and for picking at my scabs
like they could never break but they can
and They will and I’ll spill like a leak in the basement,
a drunk in the night choir,
just slur all those Words to make deadbeat that sweet old refrain,
self-inflicting my pain and therein lies the real Shame:
I heard when they were picking through the rubble
finding limbs, they sang hymns, but Now what of what I sing?
The worry, the wonder, the shortness of days,
The replacement for purpose,
The things swept away by
The worry, the wonder, my slightness of frame,
The replacements for feeling,
The casual lay. And
The worst of the wildlife wears clothes and can pray and
The worry, the wonder, for three meals a day.
Only death unimpeded, not slowing it’s pace,
