pemb interior columns
for a typical 3 span gable roof pemb frame, what are the designer's assumptions: the interior pipe columns pinned top and bottom and all the lateral load carried by the exterior tapered columns? or all columns (interior and exterior) work together to resist lateral loads in frame action?

interior pemb columns are 99% of the time just pinned-pinned pipe columns that are axially loaded only. lateral is taken by the exterior columns.
if they are pipe columns i agree.  however, it depends on the connection if wide flange colunmns are used.  
in general though, what v427 says is true from my 30 years of experience with pemb's.

pemb = pre engineered metal buildings, right?

now that i have determined what you mean by the acronym pemb, i would say that the columns all work together to resist lateral forces, notwithstanding the obvious fact that the interior columns take a very small portion of the applied horizontal load.

yea...  pemb's...
we ought to atart a forum string for anachronisyms.  then again, i think that's already been done.

instead, why don't we define our acronyms at the start of our post?  i believe that is standard practice in the field of journalism.

journalists, we are not, thank god.

i think we should strive to improve our communication skills.  if we don't, we really have no right to criticize journalists.  i agree with ba about acronyms.  they are the bane of this site.
yes, what does ba stand for?
