Notion load factor for 0.002 or 0.003

hi

good day everyone.

I have a question about NOTIONAL LOAD FACTOR .

Regarding to AISC 360-16 PAGE 16.1-27 as shown below.

(c) In structures to which Section C2.2b is applicable, in lieu of using τb < 1.0 where
αPr /Pns > 0.5, it is permissible to use τb = 1.0 for all noncomposite members if a
notional load of 0.001αYi [where Yi is as defined in Section C2.2b(a)] is applied
at all levels, in the direction specified in Section C2.2b(b), in all load combinations.
These notional loads shall be added to those, if any, used to account for the
effects of initial imperfections in the position of points of intersection of members
and shall not be subject to the provisions of Section C2.2b(d).

1.

I try to realize the meaning of that. and if tau-b =1 and notion load will be 0.003 ,

is that right ?

2.

and I try to write the syntax in staad as show below.

DEFINE DIRECT ANALYSIS
FLEX 1 ALL
AXIAL ALL
FYLD 235000
NOTIONAL LOAD FACTOR 0.003

besides these syntax , is that any syntax I need to take care?

thank you.
