WebFlange local bending (J10.1) is based on a yield line analysis, which assumes a flange on each side of the web. It might make sense to assume only half the yield lines can be developed at a channel flange. Web local yielding (J10.2) assumes a distribution of 2.5:1 through the flange thickness and the fillet (k-distance). WebWhile designing cold-formed steel beams, local, distortional, bending, web buckling, and lateral-torsional buckling must be considered. The addition of a stiffened element at the web area and edge stiffeners at the flange significantly improves the flexural strength and behavior of the beams. incoming mail server for icloud for outlookWebOct 11, 2010 · The localized stresses due to local bending effects imposed by wheel loads calculated at points 0 and 1 are to be combined with the stresses due to the Case 2 loading specified in paragraph 3.3.2.3.2 of this specification.

"Weband flanges to prevent local buckling of I-shapes before they attain the desired stress level. While significant research has been conducted on local buckling of I-shapes under strong axis bending, very little has been done on local buckling of I-shapes when they bend about their weak axis with the action of a superimposed axial force.
