Turn of the century: Brick arch - remove a "slice" at the edge?

[JoRoT]

I need to take down a "slice of cake" from one of the sides of an old brick arch where the wall is load-bearing for the property. The question is whether the "slice of cake" serves any function or if it can be removed without degrading the construction so that it needs to be reinforced with an iron beam. Please see the pictures. What do you say, constructors?

Probably it is vital for the load-bearing capacity, do you know if the vault is masonry or cast?

The vault is self-supporting, and if a piece is removed from one end, the rest will collapse, not good. Just think about how stone bridges look in their construction. If parts are removed, everything falls.

To know for sure, one should remove the plaster on one side to see whether the arch continues or not.

To know for sure, you have to remove the plaster on one side so you can see how the arch continues or not.

You cannot remove the part of the wall that has been painted red where the arch ends and black for the arch support. The arch is bricked.

You cannot remove that part of the wall that is painted red where the arch ends and black for the arch's support..
The arch is built..

Can you remove a part under your drawn lines? That is, approximately where the plaster is gone but preserve the part you painted?

Can you remove a part under your drawn lines? That is, approximately where the plaster is gone but keep the part you've painted?

No, everything under and at the black lines is needed to support the arch.

 

[JoRoT]

No, everything below and at the black lines is needed to support the vault..

How should one relieve with a steel beam or similar when the vault is mounted at an angle? See the post's images.

This is what an arch looks like in construction, now here with a door, but it looks the same, in an arch freely in the air. The sides down, support the entire arch and cannot be removed.

Everything depends on whether the vault is load-bearing upwards and we do not know that. It is an apartment and only the landlord can permit something, in connection with a structural engineer reviewing the whole situation.

How should one relieve with a steel beam or similar when the vault is attached at an angle? See the post's images.

You need to insert a long steel beam on the left side and notch it on the right side with..
This is not going to look good to relieve with an iron beam..

 

[JoRoT]

You need to insert a steel beam long on the left side and notch it in on the right side as well..
This will not look good relieving with an iron beam..

Shouldn't it work to support on the same side with an iron beam like this? This is floor 2 out of a total of 4. So two floors + attic above = half of the residential building.

 

[Jansson69]

If you still believe in this and want to do it, you need to take it up with the property owner and an experienced brick constructor.

Nothing can be said on a forum about how it can be done or not. Only an architect can say something. Regarding doing something with the vault, it probably needs to be heavily propped on both sides so nothing falls down. Then a beam should be put in and cast in place so it fits tightly against what needs to be supported. So start by contacting one or more construction firms and ask if it's possible and what it might cost. Such a job is not for an amateur (excuse the expression), but it's certainly a warning not to try it yourself. It won't be free. And then the question is whether the vault will remain due to the cost.
