Hello,
my partner wants a pergola, and I could use some help with the sizing if there's anyone who knows about it.
The attached image is a principle sketch but with correct measurements. It would be fantastic to manage with one post in the corner, but if it ends up being a large glulam beam, I might have to consider squeezing one in the middle as well. The crossbeams are on cc60 here.
One long side and one gable can be screwed into the house's framework.
Thanks in advance.

Mmm, I've seen and tested it, but I find it gives some strange answers, or alternatively, I've forgotten my strength of materials/mechanics. If you change the center-to-center measurement for the roof beams, the program says you need to increase their dimension, which feels a bit strange since they only carry their own weight. That the dimension of the bearing beams changes is more understandable since the total weight of the roof beams decreases.
You can probably build that with 45*70mm since it only needs to support its own weight. Personally, I would choose significantly thicker dimensions because thin wood doesn't give a solid impression. Additionally, I would size it so that it's possible to put on a real roof that can withstand snow weight, since our summers are short and cool, and pergolas are better suited to places with long sunny summers without a lot of rain.
