Compression Flange of Beam or Girder


The widened portion of a beam or girder, such as the horizontal portion of the cross section of a simple-span T-beam, which is shortened by bending under a normal load is known as Compression Flange.

In a continuous floor beam under gravity loading, the laterally un-braced bottom flange is subjected to compressive stresses (Compression Flange) near the interior support(s). To prevent lateral buckling of the flange, this region must be adequately designed.
