Switch off exterior wall

[Lockby]

Throwing the question out here before consulting a constructor...

I'm planning to open up an exterior wall to install a sliding glass door section of 4 m and 4 windows 10x16, mounted frame to frame. The wall is of course load-bearing and has load-bearing window frames. (Hultsfredshus from 1967).

I've used various calculation programs and got this from the Glulam app:







The house's width is entered according to the entire width of the house, i.e., 8210 cm. Is no consideration taken for the load-bearing internal wall located in the middle of the house?

For practical reasons, I would like to use a glulam beam 90x315 and glulam posts 90x90. Is it comparable with the recommendation above?

I now see that I used the wrong calculation example. The opening should be 4000 mm, not 3700 mm as in the picture.
