A reinforcing arrangement (1) for an opening in an aircraft fuselage structure has a fuselage skin (2) having an inner side (3), an outer side (5) and a first opening (8) with a first opening contour, and a reinforcing structure (4) having a thickening section (10) and at least one projecting profile (16). The first opening contour is surrounded on the inner side of the fuselage skin by an opening edge surface (6), which has a thickness that corresponds to a thickness of the fuselage skin surrounding the opening edge surface. The thickening section (10) has a bearing surface (11) matched to the opening edge surface and has a receiving section (15) which faces away from the bearing surface and surrounds a second opening (9). The at least one projecting profile (16) is arranged on the receiving section (15) and extends in a direction away from the bearing surface (11). The reinforcing structure (4) is in one piece. The fuselage skin and the reinforcing structure are composed of a fibre-reinforced plastic containing reinforcing fibres embedded in a plastic matrix. The bearing surface (11) is in surface contact with the opening edge surface (6), and the reinforcing structure is connected to the fuselage skin, with the result that the first opening and the second opening lie one above the other.
