The roof above the patio door is sinking
Hello!
In 2011, we installed a sliding door section where a smaller patio door previously existed. We opened up the exterior wall from 130cm to 280cm.
We filed a construction notification, installed 2 steel beams, and put in a sliding door.
The doors have been sticking for the past 4 years, and we believe it's due to the pressure from the roof on the load-bearing beams.
242.5cm from floor to ceiling at the ends, 241cm in the middle of the door section.
We recently opened and inspected the sides and middle, and the installation work of the beams and sliding door looks okay.
Cracks on the exterior facade, have a video.
We have searched for a structural engineer to concretely find the cause and provide suggestions for a remedy (that profession is quite busy given my poor results).
Do you have any tips?
My wife is really worried...
Thanks

Is the wall the support for the roof trusses? It doesn't look like there's a floor above? Perhaps the most important question, what does the person who designed the steel beam say when you opened it up? Or did you mention two steel beams?
Hello,
No upper floor, souterräng house where the exit in question is on the upper floor.
That is something to investigate, those who installed the two steel beams. Don't know.

On the advice of an engineer (who has not seen the construction), I have tried to reduce the risk of collapse by putting up a brace under one of the beams.
I would start by investigating what it looks like. I don't understand what the "two steel beams" are doing there. Usually, you install one. Maybe there are two angle irons on either side of the existing support?David Noorzoy said:
Anyway, you've written that you did it, so I would turn to "them" who did the job first. If the wall is a support for the trusses, based on what you're showing, it seems that the support might not be sufficient.
Very difficult to give a good assessment from your pictures, but some reflections arise.David Noorzoy said:
Hello!
In 2011, we installed a sliding glass door where a smaller patio door previously existed. We opened up the exterior wall from 130cm to 280cm.
Made a building notification, installed 2 steel beams, and sliding door.
The doors have started sticking over the last 4 years, and we believe it’s due to the pressure from the roof on the supporting beams.
242.5cm from floor to ceiling at the ends, 241cm in the middle of the door section.
We recently opened and looked at the sides and in the middle, and the installation work of the beams and sliding door looks okay.
Cracks in the facade on the outside, have a video.
Have sought a construction engineer to concretely find the cause and provide suggestions for action (that professional category has a lot of work considering my poor result).

1) It looks like it "sags" in the middle when viewed from inside. Should be an impossibility if the steel beam is correctly calculated. If there was a settlement, I think it would look different. For example, a crack in the plaster on one or both sides.
2) The brick beam on the outside has certainly settled. Why? Could the brick beam previously have been connected to the wooden construction that was removed and replaced with a steel beam? Not likely in my opinion. Therefore, I wonder if the steel beam has been attached to the brick beam? That was probably not the intended construction when the house was built. Has the steel beam therefore pulled the brick beam with it?
I can’t see any other option than for you to strip off the plaster so the steel beam and the posts it rests on are visible. Only then do I think you can determine a bit more what has happened.
If you have C-drawings, upload them.
Many good comments with good questions that I don't have answers to. Further investigation is required, have access to good carpenters they recommend construction engineer.
Thank you
Was advised to take it up with the insurance company.

The insurance company has responded
No insurance claim as it appears. If further investigation shows a cause that is classified as an insurance claim, they can reopen the same case, e.g., pipe leak, incident during storm, etc. Not settlement over time, etc., due to construction.

That was probably not so expected, unfortunately. I'm curious about how it looks. You might have to tear down the interior wall to see how the opening has been unloaded.David Noorzoy said:
Not surprising. Take a tape measure and measure from the ceiling to both ends and to the middle. I don't know if the picture is deceptive, but it looks like it sags in the middle. You can also take a control measurement from the floor to the same points.David Noorzoy said:
Thank you.
From the right side when viewed from the inside, it is 242.5cm from ceiling to floor, in the middle 241cm, and from the left 242cm. Dip in the middle.
