If d/tw≤85.
No stiffeners are required.
If 85≤d/tw≤200.
Vertical stiffeners are required.
If 200≤d/tw≤250
The Vertical stiffener and one horizontal stiffener is provided at a distance of 2/5 from the compression flange to the neutral
If 250≤d/tw≤400.
Plus one horizontal stiffener at neutral.
At support and concentrated load.
Bearing stiffeners are provided under concentrated load to avoid local bending of the flange as well as local buckling of the web.
