Hello, I have a structural question about a wooden truss. The truss can be seen in Fig. 1. The structural system of the existing structure is shown in Fig. 3. On the far left outside, no beam was installed. We would now like to remove the beam of the door and move it to the edge. For this purpose, we have already removed the crossbeam of the door and removed the masonry for the support with a prop (see Fig. 2). In addition, we would also like to remove the crossbeam that connects from the other side (see Fig. 4). This is supposed to create two rooms. A new wall should be built crosswise to the beam that remains from the former door (see Fig. 5). My question now is whether this is structurally unproblematic or if additional measures need to be taken. I am grateful for any help.

Timber framing must always be considered as a whole system and not wall by wall. You have to think of it like a tent, where you also cannot simply remove struts. At least an experienced carpenter should look at it, preferably even a structural engineer, before you continue to tinker there by chance.

I am sure, however, that the breakthrough you want is too wide if you remove the [Ständer]. I seem to remember that with the normal beam dimensions in old half-timbered buildings, the distance between two supports normally must not exceed 1 meter.

Hey, thanks first of all for the feedback. The carpenter said up to 4 m is fine. The larger breakthrough on the right is 2.24 and on the left it is 1.40 m. Loads come from above from the unfinished attic.

Since 4 m struck me as quite large as a statement, I wanted to ask here again.

Can the loads then still be transferred via the new wall if it is designed as load-bearing?

... and therefore, far too few fundamentals are presented here. We would also need plans. You cannot simply proceed here with the method "house of cards backwards," i.e., "if the house does not collapse after one measure, you continue with the next," Learning by Survival Challenge.

Hello 11ant,
attached is the floor plan (Fig. 1) and how the walls are supposed to be rebuilt (Fig. 2).
