Hi, planning to tear down part of a wall for an open floor plan in conjunction with a planned kitchen renovation. The open section will be the red section on the floor plan image. Three of the trusses will then lack support. Only the outer walls are holding them up. The trusses are of truss type and dimensioned according to the drawing below. According to the truss handbook from Svenskt Trä, the maximum span is 9 meters in my snow load region for a corresponding W-type truss, but I have WW, which should be stronger, but I can't find it in the table. In my case, the distance between the outer walls is almost 10 meters. The house probably won't collapse, but is there a high risk of deflection, meaning the ceiling might start sagging?
Hello,
I would say that the roof trusses span from outer wall to outer wall. Detail F shows that there is a stud/wall under the left sheet. None of the other details at the subframe (K, M, O) show any underlying stud/wall. Then it could be that the wall has become somewhat load-bearing over time and that the roof has settled a bit more than before, but since the roof truss is dimensioned for a span of outer wall to outer wall, that deformation should be within reasonable limits.
