Explanation:

As per IS 800:2007, for steel structures:

  • When a column is subjected to axial compression and bending, the maximum permissible slenderness ratio is 180.

This limit ensures the stability and safety of compression members under combined stresses and helps to prevent buckling.

Additional InformationOther Slenderness Ratio Limits (for context):

  • 250 – For members subjected to axial tension.

  • 350 – For members under compression resulting from wind or earthquake forces only (temporary loads).

  • 180 – For columns under combined axial compression and bending (as in this question).
