Hello!
It seems there are a lot of knowledgeable people here, so I thought I’d ask if anyone could help me with a little problem.
I have a console that consists of an HEB220. Cut longitudinally, so it’s about 60mm long. This is, of course, made to stand on the ground, and then you can apply a lot of force to it.
Now to the crux. I want to instead mount this on a wall. Due to various circumstances, it must be rotated 90°, which means the beam web becomes horizontal, and the beam can then absorb about as much force as red milk. The only thing bearing is basically the same as a horizontal flat bar of b60 h9.5.
I want the beam to be able to take a directly downward point load of 1500N, and this point load is placed about 360mm from the beam’s fixed clamping in the wall. The things holding the load in the space between the beam's 220mm and my 360mm are not a problem. But I obviously need to reinforce the beam web. I’m thinking of welding a vertical flat bar on S235 60x8 as reinforcement on the underside.
With that said, is the following calculation correct if I want a safety factor of 2:
S = 235/2 = 117.5Mpa
F = (b*h²*S)/(6*L)
F = (8*60²x117.5)/(6*360)
F = 3384000/2160
F = 1566N, which is more than my desired 1500N
Here, I haven’t accounted for the cross-section of the beam web either, which should give me a little more strength.
It would be great if someone had the desire to "correct" me. Many thanks!

Do you mean that you have a cross-section height of 60 mm? Can you attach a sketch of your problem so one can see the beam, the load drawn, etc.?
Attached you have a rough sketch. I fully understand that this is completely the wrong way to use a beam, but I would like to avoid building something else. So it would be great if it sufficed to reinforce with a piece of flat bar.S scorp1on said:
Edit: The load is clamped to the nearest "flange" on the beam (the flange on the left in the sketch). Building up the space and holding the load in the beam's flange is not a problem, but the problem is the beam itself.
