Flange Width vs Deep of Beam Limit Criteria
Flange Width vs Deep of Beam Limit Criteria
(OP)
Hi, i am designing a truss bridge. Is it possible to use fabricated steel section like I girder with 450mm deep [gross], 550mm width flange, 35mm thick web and 40mm thick flange?
I know the boundary in AASHTO/AISC for limiting the minimum width of flange and thickness of flange and web due local buckling, but i don't seen any maximum limit of flange width versus deep of beam of I girder.
Is possible to use larger width flange I girder/member comparing to it's deep?
Regards.

This is for truss bridge, not for composite bridge with slab.
Effective width to Beam theory? I don't know. What i know is Timoshenko Beam theory consider the shear coefficient. It's that what you mean? I think it only effects on bendings which minor in this truss bridge beam.

(you know that you cannot design too wide flange girder if it's a bending element)
