It depends on how much wind load, what species of wood (for design values) and how much deflection you'll allow. You can only go 22'-11" if you follow the NDS slenderness ratio (50x5.5" = 275"/12 = 22'-11") In practice, you'll probably not be able to get a 30' wind wall out of 2x6s. Too much deflection, which is usually limited to L/240. You'll probably want to use engineered wood products. Trus Joist makes 2x4, 2x6, 2x8, 2x10, 2x12 and 2x14 studs out of TimberStrand LSL (E value of 1.5million psi) that are perfectly straight, every stud is the same (no picking out the straight ones) and have pretty high design values. You may have to go to an LVL or PSL product to limit deflection (they have E values from 1.9-2.0 million psi) Mike Perakis >>> bryson(--nospam--at)civil.ubc.ca 12/04/00 04:26PM >>> What would be the maximum height for 2x6 wood wall studs carrying only wind load? If you finger joint them or double them up and splice them can you get 30'-0" clear?
