Hipped canopy, correct dimensions and considerations?

[painless]

Hi, I'm going to build a hip roof, with a long glulam beam 66x315 running diagonally, resting on a glulam pillar of 115x115 on the outer side and attached to the facade on the other side, which consists of cladding and then logs. A 115x115 pillar is then placed around the two sides without a facade. The rafters from the beam are 45x170 studs.

The roof slope will be 12-13 degrees, with tongue and groove followed by a sheet metal roof, snow zone 2.0.

Is it sufficiently dimensioned? Will a number of structural screws fastening the glulam beam to the corner against the facade work?

Grateful for your answer.

Even though the construction is not clearly depicted in your sketch, I dare say that 66x315 is too flimsy in relation to the long span (7.9 m). It's more about 90x495 or in that range. I also don't believe in attaching the beam with construction screws. It's about a load near 2 tons.

Hi, okay thanks for the answer, any tips on how to secure a glulam beam to the corner of a house?

Place it on a pillar attached to the facade.

Thanks for the tips, now I have some new things to think about.

I had welded together a sturdy steel angle that I fastened with lag screws in the timber frame, which the glued laminated timber beam can then rest on.
