N-, V- and M-diagram

    Certainly, this is not a truss, because of q. Can anyone explain how I can draw the N-, V- and M-diagram for the structure?

    Does this problem comes with a statement?, usually a roof or slab is supported by beams which receive the load from the slab and then send it to the truss as point loads. This structure as a whole is unstable.

    No, there's no statement. But AD and DB is to be regarded as two simply supported beams.

    Actually, it's not unstable, but you might want to look in our tutorial section, there are a couple of tutorials that explain how to draw the diagrams.

    I know how to draw the diagrams on normal beams, but not in this particular case.

    You'll have moments on the AD-DB part only, unless I'm missing something.

    That's right. This is a trussed beam (or 2 trussed beams).
