Hello!
Our fence standing on the roof of our concrete garage has started to lean outward. The cause is that some of the beam shoes have bent, probably because the fence was too heavy.
See pictures!
I would like help with the following:
1) A "quick fix" so that we can temporarily secure the fence in the most aesthetically pleasing way possible.
2) A long-term solution so that the problem does not recur
Thanks in advance!

Looks like it's the wrong type of beam shoes. They seem to be the ones with a thick round bar in the middle that fastens into the concrete?
They can only handle loads straight from above. They are useless for side loads.
You should have the thickest flat/plinth iron you can find, preferably 8x40 or thicker, 2 per post.
There will be significant wind loads on fences.

As a temporary solution, you can screw down stormankare into the grass and tie up the fence to these. Not a pretty solution, but it will fall in the "right direction" then.
The risk is that the balkskor can break when you bend up the fence.
Edit: They're called stormskruv.

Hello!
Oldboy: Yep, unfortunately, it's just regular joist hangers with thick round bar. Thanks for the tip with the flat braces! I assume you're supposed to place the braces with the thin side against the bending direction, i.e., on the sides of the posts, not front and back.
Marcus: I had a similar solution as you described as a suggestion, but unfortunately, it wasn't approved by the wife ;-)
Now I've taken down the entire fence instead. I think I need to put up a lighter one and use post anchors, just as Oldboy suggests.
Thanks for your responses. Have a nice weekend and summer!

I'm not sure what provides the greatest stiffness.
The irons themselves have the greatest stiffness as you suggested their placement, but if you put them the other way, i.e., on the front and back of the fence post, and use a through-bolt, one will likely act as a "hinge" and the other will take most of the load as tensile load. The lower to the ground the post goes, the stiffer it becomes.
But as I said, I'm not sure what makes the stiffest fence. However, if the irons are "sufficiently" thick, it probably doesn't matter much how they are set. I just know there will be quite large forces since the height of the fence becomes a lever and creates a lot of torque.
The stiffest fence would probably have the posts go down a bit on the side and be fastened at the bottom into the side of the wall, and also with an iron from above, but that might be overkill.
