Even if you used the QR reduction, and you got the design area down to 900 sq. If you want to sprinkle between every truss (sprinklers spaced at 16" intervals!!) be my guest.

I can agree that words alone are hard to interpret.

Running through the widest open space, you'll be 8" horizontally from each truss, plus the diagonal distance from any member. If the truss is 18" deep as you state, call out your branchline el. However, the fitter will hang the line through the opening in the truss, so your measurement would be taken diagonally from the nearest member. By looking at a plan view of a 16" OC truss layout, then no, you couldn't get 10.5" away. If they were 24" OC, would you not be 12" from each truss, measured to the centerline of the head, if the head is centered between the trusses?

Better yet, with the help of Boise Cascade ® software suite, you can design, size, and analyze with just a few clicks. Just quiet, solid floors that stand the test of time. RE: Open web wood trusses carlosgw (Mechanical) BCI Joists make it easy and cost-effective to reduce floor vibration and improve customer satisfaction. These joists include wide flanges that give greater surface area for nailing and more support for floor sheathing. Of course, the above is my interpretation, and I may be corrected by some of the more knowledgeable members. The I-joist is a manufactured wood joist, constructed of either machine stress rated (MSR) lumber or laminated veneer lumber, that is lightweight and easy to handle but able to carry heavier loads than dimensional wood. Is the 2x4 deeper than the height of the triangle? The depth of the 2x4 member is what you now take into consideration. You've stated that the webs are made of 2x4's. Your least dimension would be the shortest side of the triangle (likely the "height"). To answer your latest question, think of it this way: The opening in the truss are going to be triangular. If the openings are less than 70% - Obstructed. Unobstructed construction has horizontal members that are not solid, where the openings are at least 70 percent of the cross-section area and the depth of the member does not exceed the least dimension of the openings, or all contstruction types where the spacing of the structural members exceeds 7 1/2'. N3.7.2 Unobstructed Construction: Construction where beams, trusses or other members do not impede heat flow or water distribution in a manner that materially affects the ability of a sprinkler to control or suppress a fire.
