Its been ages since I posted but I need your help.
In my shop I have a 5x12 (actual size) 15' free span wood beam that supports
2x10 2nd story floor joists on both sides.
I noticed a small crack/split starting at a knot a few months ago and now
its growing so I put up a temporary support post in the middle of my work
It's time to fix the problem:
I have a 6"x6" 15 lbs per ft H-beam that I intend to put under the wood beam
and support by 6x6 posts at each end.
If I mount the H-beam on its side, I gain 3" overhead clearance vs flange
side up. But what does this do to the load bearing of the H-beam.?
If it reduces it by say 10% then no problem. But if it reduces it by 75% its
not worth the height gain and may not meet my floor load needs.
My question: What's the distributed load bearing of a 6x6 15lb/ft H-beam in
normal orientation and what is it when turned 90 degrees????????
If I mount it on its side I would weld a plate on both ends to tie the web
and flanges together and I can constrain the sides (flanges) from side
buckle by the wood beam (with shims) above and welded struts below.
