Calculating Ridge Beam Size. Steel beam calculations accepted by building control. You have to add the 1.5 inches because that accounts for the king rafters that connect to each end of the ridge board just like the common rafters.

1200 *z=21900, so z needs to be 18.25. But remember this beam size is recommended for residential building. The only time you would ever need to use bolts would be if the material had such severe.
(1) No Attic Floor (Ceiling) Joists, Such As For A Sloped (Cathedral) Ceiling.
1200 *z=21900, so z needs to be 18.25. Pick a 12 height, so 18.25 = b* (11.25^2)/6, thus b is less than 1.5 so a 2x12 will work. Work out steel beam weight, width and depth.
For Example, You Might Need A Hip Roof Framing Calculator To Work Out The Depth And The Range Of The Frame That Is To Go Up, To Make Sure Everything Can Be Cut And Prepared To The Right Size.
