D8.B.5 Stability Requirements
Slenderness ratios are calculated for all members and checked against the
appropriate maximum values. Section 3.7 of IS:800 summarizes the maximum slenderness ratios
for different types of members.
In the STAAD.Pro implementation of IS:800, the appropriate maximum slenderness ratio can be provided for each member. If no maximum slenderness ratio is provided, compression members will be checked against a maximum value of 180 and tension members will be checked against a maximum value of 400.
