I was keeping it simple, Bob ; ) The Steel Institute handbook is lying
around here somewhere...under something....

If the handbook is lying, I wouldn't trust it./

Actually I made a mistake. I am spanning 50ft with the steel. Figure to
do it in 2 sections with a post/piller. 2X 12's on top for floor joists
This will be the floor for a single story ICF home. Aside from the
wooden beams is there something better out there besides steel I [w]
beams for this. Maybe something lighter.

Sounds like you plan (2) 25-foot spans that must support an ICF wall, the
floor and a roof load. I suggest you talk to a local engineer to have the
support beam properly sized and to review the system of resisting lateral
forces.

I'm not trying to run up your costs, but what you are proposing is non-
standard construction and most building officials will want to see
engineering for the design of such a system.

That's a mighty big span, pardner.
