A very rough, napkin-scribble estimation goes something like this: most span tables say doubled 2x12's are good for 12' openings. You have 18', which is 50% wider. Thus, the header will need to be 1.5x1.5=2.25 stronger than the one for a 12' opening.So an 8-foot tall wall weighs 8 ft x 16 pounds/ft 2 = 128 pounds per lineal foot. The loads delivered to the header are: Conditions: live load (snow): 50 psf x 14ft = 700 pounds per lineal foot. roof dead load: 15 psf x 14ft = 210 pounds per lineal foot. upper level wall: = 128 pounds per lineal foot.25-Sept-2013 ... i tried consulting span tables, and it looked like i would need a triple 2x12 for about 11ft only. double 2x12 for 16'? is my ceiling going to ...OK, let's use common math. Your 2x lumber is 1 1/2" wide, for for a 5 1/2" span you will need 3 2x's with 2 pieces of 1/2" plywood between the middles. That is correct. There's no "table", just math. I am talking about a SPAN table. The point being - with 2x6 framing, you have room for 3 2xs rather than 2.
