why not include the column in the wall if that is possible and not affect the structure. that way the wall would not have to be built as load bearing and the other thing you would need to consider is if the floor slab could support the increased weight on it from the load bearing wall. the column prob has a deeper footing than the floor slab tkickness isHere's a n00b question, but do you have any columns in your basement, or are there load bearing walls in your basement? I toured a house this weekend that I'm thinking about buying that had cylindrical metal columns holding up steel I-beams for structural support of the 1st floor. If I were to put a load bearing wall there, how would I erect such a wall while simultaneously removing the columns and keeping my house standing?
we made our own out of 2x4s but a real hoist would have been a lot easier.I found a sheetrock hoist (or whatever its called) at a pawn shop for $150 bucks, that should make the sheetrock on the ceiling go pretty smooth. It was going to be $40 / day to rent and this way i can take my time (& then either pawn it back, craigslist, or take it to the dump when i'm done) :0
As stated above, most wall framework will enclose these steel braces (I think a 2x4 wall is thick enough for most, some require 2x6's). Then you haven't changed any of the structural integrity of the building and if you want to tear down the wall in the future, you don't have to re-engineer the bracework.Here's a n00b question, but do you have any columns in your basement, or are there load bearing walls in your basement?

The metal columns might only be there to satisfy building code requirements of maximum dimension between supports for a residential structure (and the codes are based on main beams of wood and not steel I-beams).Here's a n00b question, but do you have any columns in your basement, or are there load bearing walls in your basement?

That certainly isn't the case with this house. The steel I-beam is actually split into 2 sections because the load bearing walls upstairs are not 1 continuous wall. So the beams actually end in the middle of the room with a column right under where they end. It's bizarre, but I've checked with the structural people at work, and they say it's kosher and quite common.The metal columns might only be there to satisfy building code requirements of maximum dimension between supports for a residential structure (and the codes are based on main beams of wood and not steel I-beams).
A friend had a house with a steel main beam with lally columns in the basement. He wanted to put in a pool table and needed to remove a column to do it. He hired a local structural guy that reviewed his house and framing. the engineer concluded that the steel I-beam alone had sufficient capacity to handle the loads and span the full distance. i.e. the lally comun was not necessary. A contractor removed it with no repercussions.

So do you just cut the top and bottom plates of the wall around the columns? It seems like that would screw with the structural stability of the walls.
You pretty much got it. I don't know why I was thinking of splitting a wall around the columns instead of just putting a section of wall on either side of it. Brain fart, I guess.wil:Maybe, I'm not following you. I am envisioning a main beam down the center of the house supporting floor joists which span between the main beam and the foundations, perpendicular to the main beam. I believe that you want to make a wall parallel to the main beam and centered on it so that you create two rooms: one in front of the house and the other to the rear dividing the basement. Is that correct?
If so, you really just want to infill between the existing columns. The new wall will not be "load bearing" because it's really just sitting below the existing steel beams which will continue to support the upper floor just as they are now. Your new wall will just cover the columns. I don't think you'll have any problems just putting a couple of fasteners into the bottom flange of the steel beam to hold the top wood framing for the new wall and give it some lateral stability.
hope this helps.
I've never heard of a free-standing stud wall - the article was BS - attaching to the underside of the I-beam will be tough, but however you frame it, run the studs right to your top plate.Here's another stupid question. How do you attach the walls in the basement? I read something that said you need 3/4" of "play" between the floor and ceiling for expansion room. So, you nail the baseplate to the floor with concrete nails, but how do you attach the top with that 3/4" gap? Or was that article just BS?
I've installed free-floating walls before. Granted, they were in an attic space and weren't very tall. They had to have a 1/2" to 3/4" gap to accomodate the movement of the roof under snow loads. I'll have to look-up the article on how I did it, because I'm horrible in trying to explain it myself.I've never heard of a free-standing stud wall - the article was BS - attaching to the underside of the I-beam will be tough, but however you frame it, run the studs right to your top plate.Here's another stupid question.

I'd just drill a couple of holes in the bottom flange of the steel and either use self tapping screw in a pilot hole or some through bolts and nuts.I've never heard of a free-standing stud wall - the article was BS - attaching to the underside of the I-beam will be tough, but however you frame it, run the studs right to your top plate.Here's another stupid question.

^yeah true - its just drilling thru 1/4" steel overhead - not gonna be fun. have lots of spare drill bits on hand - how long a span is this Dan?
