Help with sizing roof beams

[Daniel Barnaniel]

No. I can't deliver any documents.

Why not, if you don't mind me asking? I used to work at a construction consulting firm and often bid for jobs, and many things I've seen you do here would charge several thousand in fees (though with a drawing/sketch, for example).

I get paid by Byggahus when I write articles. I would also like to remain anonymous. However, it is clear that experience and competence get good exposure on Byggahus forum.

I agree, the help is invaluable!
When I calculate for a beam length of 6500mm, 3.5kN/m2, and snow zone 1, I get:
Glue-laminated timber 115×360 GL30c
Utilization rate 32%, Deformation 19 mm (L/351)
Support reactions 9.770 kN & 9.770 kN
Now to the answer key

Wrote about fees so people understand what kind of effort you make! Hope the fee from BH is sky-high!

@SSlangen: What is the center-to-center distance of the beams?
@Daniel Barnaniel: Thanks!

 

[SSlangen]

600mm

The support reactions and load calculation are correct. I'm getting a slightly lower value for the deformation, but that doesn't matter.

Thank you very much!
