Beam Reinforcement Calc

Hello,

I have a steel beam, 8Wx18 that spans 39'4". There are 3 columns supporting the beam between the concrete foundation walls. F - 9'8" - C - 9'7" - C - 10'6" - C - 9'7" - F. There is bracing every 10'. I need to move the last column on the right to the left 5'6". So the new spacing would be F - 9'8" - C - 9'7" - C - 5'0" - C - 15'1" - F. I would like to bolt C " |__| " channel underneath the 15'1" span to strengthen it. The question is what size C channel do I need so that I have the original strength or more of the W beam with the original span. If you can show the calculations that would be extremely helpful as well.

Thanks,
Jim

Sounds to me like you need a structural engineer to design that reinforcement for you, and quite possibly new foundations, too as you drastically alter the load path of that structure. There's likely to be a couple to choose from locally who can do that for you for a fee. Most of us here do this work for a fee, so we don't offer it for free here. Best of luck to you!
 
Completely understand. I have reached out to four different structural engineers in the my area and one service online without being able to lock someone in. Three of the four didn't even call me back. I suppose everyone is too busy for such a small job. Happy to pay a fee if someone was willing. Thanks for the consideration.
