Hi everyone,(adsbygoogle = window.adsbygoogle || []).push({});

Recently I faced a problem in calculating bending stress in a long UPN profile "flange" due to concentrated force.

It seems that the regular/familiar formula for bending stress in a finite/short element does not applicable in local bending of long/infinite beam. See sketch attached for clarification.

An example to such calculation I found in elevator's std for "T" rails calculation which express the stress in the "flange" root:

\sigma=\frac{1.85F}{c^2}

My question is how to calculate such local bending stress in a "flange" of std profiles such UPN/IPN...and sources/books in the subject.

Thank you,

Guideon
