Am I correct in thinking that the trusses are self-supporting?
We are going to remove the wall circled in red. The blue walls are already gone. The trusses run in the direction of the yellow lines. As I interpret the sectional drawing, the trusses should bear against the exterior walls as there are no interior walls shown on the drawing (only the heart wall in the basement).
I will probably still put a beam where the wall was, but more because I need posts for electrical outlets. But my thought is that I don't need too large a dimension for the beam.
A W-truss of the type seen in the drawing is self-supporting and not supported by any interior walls. However, the wall against the angled part is load-bearing. Understanding is always facilitated by being able to see the entire drawing. Your collage confuses more than it enlightens.
