The minimum web thickness is checked against the serviceability requirements in 8.6.1.1 and the compression flange buckling requirement of 8.6.1.2.

If these sections are not satisfied, then a warning message is included in the output, including the clause which did not meet the web thickness requirements.

This check applies to the following sections:

• Sections with a stiffened web (i.e., connected to flanges along both longitudinal edges):
  • wide flange (rolled, UPT, tapered)
  • I section with cover plates
  • double I-section side-by-side
  • channel
  • double channel (back-to-back and front-to-front)
  • tube, HSS rectangle
• Sections with unstiffened web (i.e., connected to flange along only one longitudinal edge):
  • tee
  • single angle
  • double angle
  • star angle
