F2. Flexure (Columns: AISC 360)

The member is assessed for Flexure in accordance with section F2. The following checks are potentially required:

About the x axis - within the LTB sub-length

  • Yielding
  • Compression flange local buckling
  • Web local buckling
  • Local buckling
  • Lateral Torsional Buckling (only required for I and C sections)

About the y axis in the LTB sub-length

  • Yielding
  • Compression flange local buckling
  • Web local buckling
  • Local buckling

The lateral torsional buckling checks can be switched off for any sub-length by indicating the length is continuously braced. If you use this option you must be able to provide justification that the sub-length is adequately braced against lateral torsional buckling.

When the checks are required you can set the effective length of each sub-beam (the portion of the beam between one brace and the next) either by giving factors to apply to the physical length of the beam, or by entering the effective length that you want to use.
