Such a fuselage comprises cross-members (104) for constructing a floor, at least one of said cross-members (104) comprising an upper part (124), a lower part (126), means (140-150) for connecting the lower part to the upper part, and at least one opening (152) for the passage of systems (14), said opening being defined between the lower part and the upper part. The upper part (124) of the cross-member is fixed to the fuselage and the dimensions thereof are such that it can withstand the stresses that may be applied to said cross-member when the aircraft is on the ground, and the lower part (126) is fixed to the upper part (124) in such a way as to reinforce it such that, once they are assembled, the upper part (124) and the lower part (126) can withstand the stresses that may be applied to said cross-member (104) when the aircraft is in flight. |
