With a VKR 120x60x4 S355J2H there will be no problems with strength (including calculations for a dynamic amplification factor of 1.5) and dimensioning values on the loads (the loads are increased with a certain factor beyond the dynamic amplification factor).

Looking at the deformations, I get it to be 17 mm (compared, for instance, with L/300) where I have calculated with the increased load and self-weight but not with dimensioned values beyond that.

I have calculated on a 2D frame where I have assumed a non-moment-resistant restraint in the floor (bolted).
Is such a thing available to buy per meter?

I'm very curious about how you calculated that.

Which load case are you using then?

It's possible, but it's always cheapest to buy full lengths

I'm imagining something like this, where the idea is primarily to use the stages in between (= only half the weight on each long pipe)
CAD drawing of a rectangular frame structure with vertical and horizontal beams, illustrating a construction concept with support braces.

And that you do it like this with the side posts:
3D model of a corner joint with horizontal and vertical rectangular tubes intersecting at right angles, illustrating a construction concept.
And that you have an angled plate that covers the entire corner and a bit on each pipe..

I didn't have the energy to draw everything, but let me know if you don't understand, and I can CAD a bit more :rofl:

I see, you were thinking like that, I was imagining a cube according to dkhansson's first post. I then only studied one side in the form of a frame with two vertical tubes and one that goes between them horizontally. Then I apply a load in the middle.

Oh, you thought so, I was imagining a cube according to dkhansson's first post. I only studied one side in the form of a frame with two vertical pipes and one that goes between them horizontally. Then I apply a load in the middle.
I still wonder how you calculate the load?

I'm wondering if I completely miscalculated myself? (And then I only calculated on a single pipe, simply supported, including the weight as part of the point load)

My professional experience (from the floor) feels like 31 mm with just 200 kg sounds a lot...

Edit: Found my mistake :rolleyes:

How silly it can be sometimes...

@dkhansson 80*40*5 was too optimistic of me :seenoevil::poop:

Okay how good, that's how it can be sometimes:)

And having an angle bracket that covers the entire corner and a bit on each pipe..

Couldn't bother drawing everything, but let me know if you don't understand so I might have to CAD a bit more :rofl:
By the way, what program are you using? :)

Autodesk (Inventor) at home
SolidWorks at work

that looks smart! Now I just need to find someone who sells in those sizes

Company, we are building senior residences. I'm trying to build functional gyms.

Then there are many places, like tibnor and begroup, but it may also pay off to buy everything ready-made from a mechanical workshop :)
