There's a wall in my house that I'd like to open to widen a room. The beam (a single 6x10 of hard wood) above is sitting on the concrete foundation at each extremity of the house (10in wide concrete) and there's 3 steel columns that supports it. In between the steel columns, there's a wall made of 2x3s every 16 inches (some are doubled in the center).

|-----------------------------------|< 10in concrete
|                                   |
|                                   |
========O=========O=========O======== <- support beam (sits on concrete)
|                                   |
|                                   |
|-----------------------------------|< 10in concrete
^                                   ^ 
10in concrete                       10in concrete 

O = position of the steel columns


I won't touch the 3 steel columns, they will remain where they are.

Can I remove those 2x3s?

  • you should be able to remove the wall ... i would be surprised if the top of the wall is even touching the steel beam

  • We can’t see the beam yiu say is supported by the jack posts. What size is that beam and what kind of beam is it? Does the wall attach to the beam?

  • Yeah sorry the picture is bad, on top of the steel column there’s something that looks like a 2x6 or 2x8 then beam is sitting on it. It was like that when I bought the house. The beam is a single 6x10 of hard wood. Sep 7, 2019 at 2:14

Yes, you can remove the 2x3 stud wall.

There is 1) single top plate, 2) no plywood for shear wall construction, 3) no hold-downs for uplift or “racking” considerations, 4) the steel posts are close enough together to support 17 train locomotives (well, a significant load).

2x3’s are not used for structural walls.

Is that an adjustable cap on that steel post?

  • It’s a 2x6 or 2x8 then beam sits on it. The other 2 don’t have that and the beam sits directly on it. Not sure why this one has this (was like that when I bought). Sep 7, 2019 at 2:15
