Composite I-beam question

[bud16415]

I was looking on Bailey floor joists (lsf system) and they specifically mention their being an alternative to engineered wood. I'm sure you could look at the load tables and get something of similar strength and gain the space you want. While I would never argue against having someone take a look see, if the joist you are cutting is supported on both sides of the stairwell I highly doubt it's the keystone piece that will bring your house down. or tear out the stairs and make them steeper(jk)

I agree. Say the odds are 1 in 50 something may shift in the house or the basement floor where the studs rest wasn’t poured to be load bearing. The question becomes do you want to call the insurance company and when they say why did you cut the beam? Your best answer is a guy on the internet said it would be ok.

That’s kind of the point here. In suggesting help here we have to try and access the persons abilities as DIYer along with a lot of other things based on a tiny bit of information we know about them. Electrical also falls into the same category quite a bit what is a simple job for some of us can be a deadly task for someone else.

I'm going to get into the drop ceiling to get shots of the i-beam (joist) on either side of the walls. I do know the wall going down the stairs on the right is made up of 2X6's and is a weight-bearing wall. I believe the other side is as well, but not 100% sure. More to come... appreciate the feedback thus far.

Right at the top of the web but a 2x6 on both side of the web.
Over the wall put blocks to support the 2x6s and cut the center out.

Really appreciate this diagram. Thank you.

When you have a serious load from above you would find beams where that is.

I think both walls are load bearing and even if one is not, asking the slab floor to support one joist is not a big deal.
