enter image description hereI am trying to take down a load bearing wall and have had an engineer draw plans and advise I use a steel beam and columns to support the floor above. Do I need something to secure the columns to the floor so they do not move or can the rest direct into the concrete floor? I live in Scotland which tends to have different laws than the rest of the UK.

columns 90 x 6.3 SHS beam 178 x 102 x 19 UB

The beam will have JJI joists resting on it. I have a 3 floor terraced house and the work is being carried out on the ground floor.

  • Usually steel posts have plates welded to the ends with bolt holes punched in them. We'd need more detail about your columns to answer, though.

  • Not the plans so much, but the metal bits.

    yes, you want them attached, as a home inspector explained to me, in case of earthquake, kids, or accidentally bumping into one with your arms loaded. Strictly speaking, that doesn't provide support, but it provides robustness.

    I'd go back to the engineer. You may need to crack concrete and dig a new footing. When I did a similar thing, I needed to dig down 18" add some rebar, and re-pour concrete. Nov 14, 2019 at 16:48

Either the plate with bolt holes as suggested.

Or you could bolt some blocks to the floor on each side of the beam to stop it moving - especially if it does not have a plate already.

But some method of stopping it moving too easily is sensible - "just in case"...

  • If blocks were used, you’d want them on all 4 sides of the column to keep it from moving in both directions.

  • @LeeSam each side... means all four, not any two of choice...

  • Exactly. Regardless of local code, failure to secure posts at either end is a ReallyBadIdea(TM) Nov 14, 2019 at 19:03
