non bearing interior wall detail > 12'
using 2003 ibc will a 13' tall interior non-bearing wall using the following material pass code?
1. studs braced with 5/8 gyp board ea. side.
2. 25 ga 3 5/8 tract and stud.
3. bracing @ 4'-0" o.c. staggered 3 5/8 25ga.
the 2 walls are for a restroom addition and are attached to an existing demising wall and exterior wall. wall lengths are 7'2" and 6'4". ceiling is 25ga 16" o.c. @ 8' with 5/8 gyp board.
thanks in advance!!!!!
go online and look up "the steel network" or "marinoware". they should have limiting wall height tables available. the tables i have say no. you need to either use a shorter wall or a heavier gage stud...say 22ga.
i checked on marinoware under limiting heights tables (composite) using a 3 5/8"
i wasn't using the composite wall table. we don't use that table for our designs. we also don't use l/120 for deflection. we use l/240. ibc 2003 says l/120 is acceptable for non-brittle finish. according to that table, the wall will work. be sure to use a deflection track at the top of the wall if you are attaching to the bottom of beams or a floor system.
i just received an updated for the clv nv building department stating that 20ga @ 24" o.c. is good up to 16'. i guess i will just change the drawings and give my customer a change order.
why is an electrical person designating walls?
i was wondering if someone was going to ask me that. i used my cad artist to draw the plans for this small ti. we are a general contractor also, but mainly due commercial electrical. scope of work was only to close an opening in an existing demising wall, add restroom, 200a panel, and re-circuit elec. to new panel. job was too small to bring in an architect and i was told the ceiling was originally 11'. long story short, found out ceiling was 11'10", and the typical framing details that i am familiar with wouldn't pass. since i had to specify what type of professional i am, i figured i would tell the truth, instead of posing as a structural engineer just to ask a ? hope this isn't a problem.
i think we can all appreciate honesty, especially since the question itself woud have given you away as non-structural.
there is a problem though if you are practicing out of your area of expertise, partiularly if you sign and seal this work. i hope that's not the case. it's hard to say with an interior non-load-bearing wall, but is it worth it in the end? i think it's worth having a professional check what you are doing. in the end it protects you, the client and your company.
