A structure has a panel 5, a stringer 8 and a rib 14. The stringer 8 includes a stringer flange 8a joined to the panel 5 and a stringer web 8b extending away from the stringer flange 8a. The rib 14 has a rib web 14b and a rib foot 30. The rib foot 30 has a rib foot flange 32 that is joined to the stringer web 8b, first and second rib foot base parts 31a 31b that are joined to the inner surface of the panel 5 or to the stringer flange 8a and a rib foot web 33 that is joined to the rib web 14b. The rib foot 30 is formed as a single folded piece such that the rib foot flange 32 is connected to the rib foot web 33 by a first folded corner 34, the first rib foot base part 31a is connected to the rib foot flange 32 by a second folded corner 35 and the second rib foot base part 31b is connected to the rib foot web 33 by a third folded corner 36. The rib foot 30, stringer 8 and rib 13 preferably form part of an aircraft wing (fig 1 & 2). |
