I'm not aware of the "industrial standard" either. Note
that for compression forces from multiple sources, the basic ASD load
combinations of 2006 IBC may be favorable (give lower loads). There
are cases where Wind is used in the calculations in combination
with reduced live load (see Eq. 16-13).

Subject: Wood SW compression check.
I am designing a 3-story wood-framed building and
checking the uplift and
compression at shear wall ends. I am using CBC
2007/IBC 2006 Alternate
(ASD) Load Combinations with -2/3DL+ (1.3)W for uplift
and DL+L+(1.3)W for
compression. My colleague told me that I don't have
to use live load
to check compression and this is an industrial
standard. He is more
experience than I am and I respect his opinion, but I
really wonder if this
is an industrial standard which I have never heard
of. Any comments or
