What is the beam supporting? One floor? Two? Attic? Roof?
Is the beam in an exterior wall? Inside? What is the joist length on each side of the beam?
Thank you. Will it support any ceramic tile?
For an 8" deep beam, you will need a W8x40. It's 8" deep x 8" wide and weighs 40 pounds per foot.
Yes, there is a way to do that. It will involve welding plates to the existing beam. I can design the reinforcement and welding requirements as an additional service. I would also include a sketch and a recommended procedure.
I would expect the reinforcement to be a little less expensive. It will have much less material cost, but that will be offset by increased labor and installation. The savings will come with not having to shore the joists from the attic to the basement for reinforcing the beam. The beam staying in place will be the shoring
It would involve welding plates to the existing beam to get the section properties where they need to be given the existing and superimposed stresses to be applied. I can do that as an additional service and provide sketches with plate information and welding requirements as well as a recommended procedure.
I'm not allowed to discuss cost in the chat. I can submit the offer for you to consider. If you accept the offer, I will work on it today and post everything you need by 10 pm today. It will most likely be sooner, but I do have some family commitments today and that is a safe time to commit to.
I just submitted it for you.
No problem. The cost will be more than offset by saving on the shoring costs. Probably tenfold.
almost certainly to the bottom of the bottom flange and bottom of top flange. There is likely no welding required to the web for added shear reinforcement.
The flanges are where the added material is most efficient.
No problem. Take your time.
I would design the reinforcement so that is not the case unless the existing beam happens to be stressed to the point where that is not possible. I don't expect that to be the case, however.
That very rarely adds enough strength. That would work for a very minor over stress, not significantly increasing the span. The reason I beams are shaped that way is because the material in the flanges are so efficient in bending
The vertical position alone is stronger, but the welding creates a composite section. I won't know what size plates or how much welding until I do the analysis.
