Steel Beam Flange Vs Web

Standard i beam and s beam the standard i beam is named for their distinctive shape similar to a capital letter i.

Steel beam flange vs web.

Properties in imperial units of american wide flange beams according astm a6 are indicated below. 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. Thus w12 19 designates a wide flange beam with a depth of 12 inches and a nominal weight of 19 pounds per foot. A wide flange beam with wider flanges and web than the i beam can handle more weight but this makes it heavier overall.

The horizontal pieces are known as flanges and the vertical piece is called the web. M miscellaneous shapes cannot be classified as standard i beams w s hp. An i beam has tapered flanges with a narrower flange than most wide flange beams making it a lighter building material. 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.

The flanges resist bending while the web takes on the shear force. Reinforcement may be for bending moment flanges or shear web. Second for the wide flange beam the width of web and flange is almost equal while for the s beam the flange is a lot narrower than the web. The width is the flange and the height is the web.

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. Hp bearing pile h shaped cross section have parallel flange surfaces and equal web and flange thicknesses. I beams are structural support materials that are primarily used. Wide flange beam dimensions chart for sizes dimensions and section properties of steel wide flange beams.

First wide flange steel beam has parallel flanges while s shaped i beam has tapered flanges which have a slope on the inside surface. S american standard beam i shaped cross section have a slope on the inner 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. Steel beam reinforcement jonathon c.

Compact web yielding noncompact web slender web nominal flexural strength mn min compression flange yielding ltb compression flb tension flange yielding 22 web local buckling cont failure mode the web of a beam can also buckle locally when the bending stress in the web exceeds the critical stress. This shape is very efficient for carrying loads of weight without bending.

I beams i shaped cross section w wide flange steel beam i shaped cross section have parallel flange surfaces.
