Steel beam flange vs web.

The flanges resist bending while the web takes on the shear force. 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 flanges and the vertical element is the web i beams are usually made of structural steel and are. The horizontal pieces are known as flanges and the vertical piece is called the web. Wide flange beam dimensions chart for sizes dimensions and section properties of steel wide flange beams.

23 web local buckling cont. Reinforcement may be for bending moment flanges or shear web. The h beam tends to be heavier than the i beam which is why some say it is better than the i beam but this is subjective as the h beam is generally heavier. Steel beam reinforcement jonathon c.

The width is the flange and the height is the web. First wide flange steel beam has parallel flanges while s shaped i beam has tapered flanges which have a slope on the inside surface. An i beam has tapered flanges with a narrower flange than most wide flange beams making it a lighter building material. S american standard beam i shaped cross section have a slope on the inner flange surfaces.

I beams are structural support materials that are primarily used. The difference between the h and i beams is the flange per band ratio. Creviston p e secb 1. H beam has wider flanges than i beam but i beam has tapered edges.

Hp bearing pile h shaped cross section have parallel flange surfaces and equal web and flange thicknesses. Properties in imperial units of american wide flange beams according astm a6 are indicated below. M miscellaneous shapes cannot be classified as standard i beams w s hp. Thus w12 19 designates a wide flange beam with a depth of 12 inches and a nominal weight of 19 pounds per foot.

American wide flange beams according astm a6 metric units for full table with depth width web and flange thickness and section area rotate the screen. Standard i beam and s beam the standard i beam is named for their distinctive shape similar to a capital letter i. I beams i shaped cross section w wide flange steel beam i shaped cross section have parallel flange surfaces. Wide flange beams are designated by the letter w followed by the nominal depth in inches and the weight in pounds per foot.

Introduction a common problem in industrial facilities is reinforcement of existing beams either due to corrosion damage increased loading or cutting of the beam in critical areas.
