Open to the ridge without ridge beam??

[Dr.SiC]

Found on this page Resaro a roof construction that seems a bit crazy. How does this work? Either you need a ridge beam or you must somehow secure the wall life so that it doesn't press apart. IF it would work, it is indeed an interesting solution.

Mmmm...

"Despite the moderate roof pitch of 38 degrees and the low wall height at the eaves, we have a ceiling height of nearly three meters at the ridge."

we wanted...wasn't possible said the house supplier...but suspected it was about the price...

It works by making all the nodes moment-stiff. Underneath, the floor beams are also moment-stiffly attached to the rest of the truss. This prevents the walls from being pushed out.

Well, of course, if it is torsionally rigid, it can handle it by definition. The question might instead be how do you make the torsionally rigid joints strong enough? The forces on them are indeed immense.

That is exactly the constructor's forte! Calculating frames is not the easiest task, especially roof frames when considering different load scenarios. For example, full snow load on one side of the house and no snow at all on the other! But it is possible... It has been a long time since I did such a calculation now.

They actually write that they have hired CSCE for the construction calculations. Does anyone know them? I assume they used "RoofCon"

Their software seems to be intended for trusses?
Can't find anything indicating that they work for frames...

Here they talk about frameworks anyway. But the website wasn't exactly an abundance of information. It seems like they only cater to registered users who appear to be truss designers and similar.
