After researching the google master wealth of knowledge, I cannot find an answer to this riddle. If I have an non-structural roof deck and the compression post must go to structure- what is the maximum deviation from plumb that a compression post can be? The guideline only indicate that the ceiling grid cannot deflect more than 1/4", the spray wires cannot exceed a certain degree angle but remains silent on the amount of plumbness required for he compression post.
Case and point, the ceiling grid is 6 feet from the steel deck. Bar joist run approx 5 feet on center. We need to angel the compression post os it is about 1 in 3. The spray wires at the bottom are all at 45 degrees as required, the ceiling does not deflect more than 1/4 inch........ but the compression post are not plumb.
Is this a problem? if it is - please direct me to the section that indicates so.
I can't find it in E580 or in the Cisca 3-4 pamphlet.
