At the one-third points

[sundy]

CSA S16-2001

19.1.5
For starred angle compression members interconnected at least at the one-third points, Clause 19.1.4 need not apply.

What does the one-third points refer to here?

Thanks in advance.

My guess; L/3 and 2L/3 along the length of the angle, (L). Plus the ends.
