Claim:
An aircraft structure comprising: a first wall and a second wall disposed within a fuselage of an aircraft, the first wall comprising two jackets each defining a plane disposed on either side of an intermediate arrangement and including at least one soleplate whereby the first wall is secured to the second wall, the structure further comprising on either side of a bottom end of the first wall at least one elongate member extending in the form of a hollow bar facing a jacket and spaced apart therefrom, the at least one elongate member being secured to the soleplate and to the second wall and being arranged to serve as an abutment for a portion of the first wall that becomes separated from the soleplate as a result of the first wall rupturing, wherein the at least one elongate member includes a bearing face for bearing against a bottom portion of the first wall after rupture, which bearing face is substantially planar and extends substantially parallel to the plane of one of the jackets, the at least one elongate member including two of the elongate members disposed on either side of the first wall and co-operating with the soleplate to define a groove-shaped receptacle suitable for containing debris resulting from the first wall rupturing.
