Handling 16m long glulam beams (roof beams)

[HEA260]

Having the beams in different measurements than the "standard solution" is a hassle. It becomes a lot of puzzling and more waste.
Trust me, I have renovated with rafters with CC varying around 750 mm.

I was also worried about this. I will check if I can find a suitable length for raw wood planks. Otherwise, I'll adjust. It's a felt roof, so nothing else that I think will be affected by a different CC than standard. I can set the studs at CC 450, as I will be installing a standing girder.

Considered masonite beams?

No, haven't worked with that before. Is it worth checking for a span of 6.2+9m?

There are no possibilities to tension the ceiling in the other direction instead since you mentioned that it required 5 beams at ~cc1m?

Definitely. I have masonite beams instead of trusses. Up to 6-7 meters span. Send drawings to them and you'll get a quote. You might need to go through a builder.

The architect and the owner do not want it that way. They want the lines to follow the existing lines. So it must be in that direction.

I'll call and check with them. Thanks!

You can still have the roof pitch in the same direction, just with the load-bearing going across the pitch. Or which lines do they mean?

Yes, towing in the other direction is likely much easier.

 

[HEA260]

You can still have the roof slope in the same direction, just that the support is transverse to the slope. Or which lines do they mean?

Hmm.. You're right, you can fix the slope with the joint later and the right height on each roof beam. But it still won't work because then I need to fix a support beam of 9m for the roof beams. Since one of the extensions is an enlargement of a living room. It becomes completely open under the beams on one side if I go the other direction.

Post a floor plan if you have the opportunity, it's easier to see that way!

@bossespecial What happened to the sole when you considered wind load (horizontal 10kN/m on the top of the sole) as well as 40kN/m vertical force.

Here you go, this is what the extension looks like in plan.

Now I had a reality check. I had mixed up the floor plan with that of another project... thought it was completely open. Maybe it works in the other direction anyway? It will be a couple of beams though, need to calculate and check with the owner if it can be accepted.

Possibly the owner had changed his mind from this floor plan and wanted it open almost all the way. Must have a meeting with him again and check what was agreed upon.

But I want to calculate a solution with an approximate cost first so I know exactly what result it will be with the direction that gives a 16m beam.

@bossespecial What happened with the foundation when you considered wind load (horizontal 10kN/m at the top of the foundation) as well as 40kN/m vertical force.

The wind load is negligible, so it is not something I worry about.

 

[HEA260]

The wind load is negligible so this is not something I am concerned about.

I just calculated with my MathCad file for the current project (should almost be considered cheating haha). And you are right!! I had gotten the impression that it played a major role for some reason.

Thank you for this discussion! I am learning a lot.
