hi @hamzabenali
In addition to what is said, if the main beams of the mezzanine link the two columns of the portal frame, the rigidity of the columns increases, moments of dead and live loads also and consequently the haunch moments of the rafters as well. You can perhaps try to release one side to return to normal or play this effect to review the inertia ratio between rafters and columns. Sometimes a post can go up to the ridge. You have an opportunity to size the first portals interested in the mezzanine independently.
