control joints in steel framed buildings
hey guys, i'm new here but this site looks pretty cool so far.
i've got an internship/job this summer at a company in northeast pa. between being on sites, and doing soil testing i sometimes go online and do some research around here. i was wondering if anyone would be able to shed some light on control joints in steel framed buildings. i know they aren't used all that much, but the structural guy here is doing a rather big 3 story building and wants some info. any help would be appreciated from a quick description, to a pic to a link or anything else because the rest of the internet isn't really turning up anything.
are you talking about expansion joints?  control joints are used in concrete, not steel.  
if so, there is a report titled "expansion joints in buildings"  technical report no. 65 which is prepared by the stadning committee on structural engineering of the federal construction council building research advisory board division of engineering national research council.  
i know that is a lot.  i am not sure exactly where it came from, i got it from someone in my office (somewhere else in pa)
i just googled this exactly as you see it  "expansion joints in buildings" technical report no. 65
the very first link that came up offered a pdf download for $18.00.
