BS 5950 Clause 4.7.10.2 (c)

Hi there,

It seems like STAAD has not taken consider Clause 4.7.10.2(c) for angle section.

"by a single bolt, the compression resistance should be taken as 80% of the compression resistance of an axially loaded member and the slenderness lamda should be taken as the greatest of : ...."

Among available option within Parameter LEG, 4.7.10.2(c) is not available.

Compression capacity for single angle with single bolt connection has not yet taken 20% reduction.

Please can anyone advise?

Thank you.
