Rule construction

[Lawrence]

I am working on my new shed and have decided on a design that I am having some difficulty determining the construction for. In the attached picture, you can see how it will look and a suggestion for the stud walls. The idea is to use 45-70 studs but 45-105 around the door and a 45-105 collar beam! (is that what it's called?)
What do you think about this?

oh now one image didn't come with

Here's an example of construction:

Hi Lawrence! I recall reading in a sizing table that rafters should be secured against something called "vippning," which is an unwanted sideways movement. One way to stop the vippning on a mono-pitched roof can be to have the wall studs run the full length. And that the stud wall at the front goes all the way up to the roof, without joints. Regards; PerOF

Hi Lawrence! I have read in a design table that roof rafters should be secured against something called lateral-torsional buckling, which is an unwanted lateral movement. One way to prevent buckling on a monopitch roof is to have full-length wall studs. And the stud wall on the front should go all the way up to the roof, without joints. Best regards; PerOF

Yes, exactly, that's what I'm worried about. The question is whether 2 pieces of 45x120 (beside the door) going all the way up are sufficient. It's a bit hard to see on the drawing. Then I can have the other verticals floating if you know what I mean.

Hello, over the opening I would want a stronger construction with a standing regel.
e.g. 45x145 or 195, depending on the load.
So a standing regel that stands on top of the wall studs, and a bracket that ensures it doesn't tip over. Alternatively, "slot" it into the wall studs.

Not sure if I have interpreted all comments correctly, but I have drawn up a new wall proposal and would gladly receive comments

Hmm, is 45x145 portrait or landscape? That is, from the front view, do you see the wide side or the narrow side? It looks, in your pictures, like it's lying down instead of standing, and then you don't really get the bearing capacity you want to achieve.

Hmm, is 45x145 standing or lying down? I.e. when viewed from the front, do you see the wide side or the narrow one? It looks, in your pictures, like it's lying down instead of standing, and then you don't quite achieve the load-bearing capacity you want.

now I'm not following, the studs are 45 mm wide and the depth either 95 or 145, the gray ones, :x

Ok, if I make it simpler, : try rotating the 45x195 rule 90 degrees and see how it looks then!

Ok, if I make it easier, : try rotating the 45x195-rule 90 degrees and see how it looks then!

oh! ok got it! I'll draw it up and check!
