What would be the proper size beam needed in the following situation?
I have a 24 foot load bearing wall I would like to remove, I have a dead load of 17#sq" (old built up gravel roof) the contributing area is 24'x14'=336sq.'336x17=5712#/24'=238# linea lfoot load on beam, there is no live load on this roof since a pitched roof has been added (Truss' have been added with bearing only at outside walls, no midspan support) i would like to know what it would take to support the old roof with a fletch beam or steel (c5x9) channels sandwiched together with 2"x6"s and flat plate steel?
Thanks for your time
