A section of aircraft fuselage comprises a body structure (2) and a floor (4) connected to said body structure. The body structure (2) has an external skin (21) and a framework (22) comprising frames (23), positioned in fuselage cross-sections approximately perpendicular to a longitudinal axis X in an aircraft reference frame. The floor (4) has cross members (41) extending along a lateral axis Y. In accordance with the invention, the cross members (41) and the frames (23) are disconnected and each cross member (41), at opposite ends (414), is fixed to the body structure (2) by an intermediate structural assembly (24, 29) connected on the one hand to the cross member (41) and on the other hand to the external skin (21) and/or to one or more frames (23).
