How to best install diagonal braces in a stud frame?
Excuse a lost cabinetmaker who has become a bit confused in the bewildering world of construction joinery. I have a small shed with a frame made of 45x145 mm studs. The height is around 250 cm, and there are horizontal braces in the middle. I want to reinforce the whole thing, which is a bit wobbly, for shear load (wind load) and I'm considering how to best attach diagonal braces in the stud bays. It feels like dovetails and finger joints are quite distant.
Dimension, narrow side out, wide side in?
On the front edge of the frame, in the middle, the furthest in?
Attachment?
etc...

Otherwise, you can screw OSB/plywood boards to the frame, avoiding the need for bands/braces.
Hålband is simple and convenient. It doesn't create unnecessary thermal bridges. What I'm worried about is durability, i.e., a brace in solid wood feels like it'll stay there for 50 years, but what about a hålband that is attached with three screws? I've looked into some special solutions on the topic, but it costs a lot:useless said:
On the outside, there is vertically mounted ventilation battens, and on top of that horizontal nailing battens that the facade is attached to. On the inside, it will be horizontally framed out with 45x45 mm for an additional layer of insulation across. Then plastic and thin battens for air gap/installation space. So even if OSB and plywood are to be put up on the inside, I'm a bit unsure about how big a difference it makes, but maybe I'm just overly worried?Isakare said:

If you're putting up OSB on the inside, that's enough. Place a board in each corner now or use perforated tape.
I placed a 45x95 regel as a diagonal brace in our gables. I held it against the framework, marked the corners on the regel and drew lines on the framework where it crossed another regel. Then I sawed 45mm deep with a circular saw in the framework and at the ends of the diagonal brace - fit perfectly. Feels like real craftsmanship. Whether it's needed when osb and plasterboard are attached doesn't matter.
