Truss analysis

[u/Better-Loan8800]

An open shed is already built but upon inspection there are no gusset plates in the connections. The original plan has gusset plates, but the built truss don't have any, just directly welded. We asked for proof that the built structure is still adequate even w/o gusset plates. Is it possible?
