Double Angle Compression Members

[ron9876]

In AISC 9th Edition the discussion for double angle compression members on page 3-53 seems to indicate that the tables are based on adding a minimum of two connections between members.

In a condition where truss diagonals and verticals are constructed with double angle members with no connections between angles it appears these tables do not apply even for buckling about the X-X axis. Am I reading this correctly? Thanks.

BA because AISC says you don't have to.

Okay, that works in USA. What about the rest of the world?
