non-bearing 35 foot tall partition wall
i have a interior non-loadbearing wall that is 35 feet tall x 50 feet long. the architect is asking what we can use to construct this wall. he would rather use wood, but wasn't sure if anyone has ever run into spanning wood 35 feet without going to some kind of engineering lumber, such as i-joist. any suggestions?
check out our whitepaper library.
light gauge steel studs- perhaps 8" or 10" wide.
i agree with sacrebleu, 8" - 10" metal studs with (5 psf interior load).
i've come across this before - i used a 'knauf' product.
one clarification to the 35 foot tall wall partition is that this project is for a wood client and only wants to see wood used to construct the building. so i don't think that light gage framing would be a idea welcomed by the client.
then i-joist would be one choice. lsl timberstrand would be another.
any external doors nearby? that is a mighty area if the wind blows.
cheers

the load on the interior partition is not necessarily 5 psf - could be 15 psf. how about large plywood sheets al la sydney opera house - maybe glulam framing - hidden or exposed as ribs.
flitch beams?
structengineer - you could use "built-up columns with mechanical fasteners" as described on page 204 in "chapter 3 - wood columns" of "wood structural design data" (free .pdf download) at this link
at 35' i would use i joists or lvl
