Are truss rafters always load-bearing?

[pjop]

Hello,

we will soon gain access to our new house, and we plan to open up the floor plan somewhat. The house has trusses of the fackverk type. Are these always self-supporting (i.e., no intermediate support needed)? Or how should we consider this?

Grateful for an answer!

If it is furnished on the upper floor/attic, it is absolutely not certain that the floor structure can support it without reinforcement.

Thank you Injonil,

the vinden is unfinished.

I assume the question is about whether it's possible to remove interior walls on the floor below the roof trusses?

Trusses typically have a longer span than "normal" roof trusses, but one cannot conclude from that that all interior walls can be demolished.

You need to examine the plans, or possibly call in a structural engineer who can determine which walls can safely be demolished.

Can I ask what kind of house it is?


Trusses can be made quite long and self-supporting.
But if the designer has access to a load-bearing wall, he will probably generally reduce the size of the roof trusses and utilize the support the wall can provide. Anything else is just waste.

The simple way to check if the wall is load-bearing is to see if any brace in the truss rests on the wall.
