Basement support column is bending
 
I have a 4 inch diameter steel basement support column that is 9.5' tall. It looked like it was bent so I ran a plumb line from the top of the column and it landed 3 inches away from the base. So there are 3 inches of flex in the column. Is this a problem or will the steel be able to handle it?

Post a picture---is it bent or simply installed out of plumb?? Big difference---

If it is bent, that is a major problem and needs immediate attention. If it is leaning, that can be a problem too, but is much easier to remedy.

I think it was installed out of plumb since the lean is consistent throughout the length of the column.

If the top is not welded, you may be able to move it over, depending on which way the beam is running. The bottom can be move, but it will require removing some concrete. I would be concerned about that.

I completely agree. Moving the column is a difficult task for the average person. I would tend to get some assistance on this one.

How old is the house?
Is this an original pole in it's original place?

Nagarjuna 06-09-2011 05:47 PM

The house is about 30 years old. The column is original.

I doubt if the safety of the house is compromised. Just some damn sloppy craftsmanship there.

If there is no sign of the beam itself shifting I believe you are good.

SPEAKING OF SAFETY, aren't those pipe columns supposed to be conc filled to resist fire ? they are also supposed to be installed on individual foundations, NOT on top of the bsmt floor :no:

at least they were in the houses i built :thumbup:

Not sure where you built, but most times they are set on footers that are just below the basement floor. You can see by the pic that the flange is covered by the floor, and it is not sitting on the floor. Never heard of any of them being filled. Maybe commercial or maybe if your using helical piers.

Any support posts I buy now are concrete filled from the steel yard. Most of the ones in the houses I've worked in, which date from the '20's to the '60's, are hollow.

Hopefully you can plumb the post where it meets the beam at the top. May not be an option though depending on which way it's leaning. As Mike said, it's just plain sloppy workanship, and I don't think there's any structural reason it's leaning.

As for concrete filled posts, I haven't knowingly seen one before. The posts we use don't even have an allowance to fill them. Sounds like a good concept though..........
