I-beams are typically made of structural steel and serve a wide variety of construction uses. The horizontal elements of the Ɪ are called flanges , and the vertical element is known as the "web". The web resists shear forces , while the flanges resist most of the bending moment experienced by the beam.
Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section .
The central "web" of the steel I-beam is often wider than a column web to resist the higher bending moments that occur in beams. Wide sheets of steel deck can be used to cover the top of the steel frame as a "form" or corrugated mold, below a thick layer of concrete and steel reinforcing bars. Another popular alternative is a floor of precast ...
The American Institute of Steel Construction (AISC) is a not-for-profit technical institute and trade association for the use of structural steel in the construction industry of the United States. AISC publishes the Steel Construction Manual, an authoritative volume on steel building structure design that is referenced in all U.S. building codes.
In a plate girder bridge, the plate girders are typically I-beams made up from separate structural steel plates (rather than rolled as a single cross-section), which are welded or, in older bridges, bolted or riveted together to form the vertical web and horizontal flanges of the beam. In some cases, the plate girders may be formed in a Z-shape ...

The steel shell of a Lally column is filled with concrete, which carries a share of the compression load, and helps prevent local buckling of the shell. The advantage of a Lally column over a conventional structural steel is that it can be cut it to length on a construction site with simple hand tools such as a plumber's pipe cutter or a ...
Architects, engineers and builders found it difficult to compare rated capacities and to use fully the economies of steel joist construction. Gable steel joists being erected. Members of the industry began to organize the institute, and in 1928 the first standard specifications were adopted, followed in 1929 by the first load table.
