Column flange stiffeners

This window contains properties of column flange stiffeners. Following stiffener types are available:

Partial horizontal stiffener of column web

  • The horizontally placed stiffener, that is welded both to the column web and flange. The stiffener increases the column flange bearing capacity in bending. It may also increase the bearing resistance of column web in tension or compression.

Stiffener of column flange

  • The flange stiffening of vertically placed plate. It increases the bearing resistance of column flange in bending.

Stiffener dimensions

Following dimensions have to be specified (the meaning of entered dimensions is described in the scheme in the left part of the window):

a1

  • The distance of top edge from reference level

aw

  • The weld thickness

ts

  • The stiffener thickness

hs

  • The stiffener length

The stiffener can be temporarily switched off with the help of the button "Consider stiffener". The stiffener dimensions remain in the window, however, the stiffener is not considered in the analysis. This feature can be used for fast review of bearing capacity with and without stiffener. The setting "Stiffener on the left" mirrors the stiffener on the left column flange.

The theory is described in chapters "End plate or column flange in bending, bolts in tension" and "Column web in tension and compression".
