Two difficulties are inherent to rib design: the multiplicity of load cases involved and the mechanism through which the loads are transferred from neighboring components such as spars and skin panels to the rib itself. Both difficulties can be overcome or significantly alleviated by the optimization procedure devised in this paper. The basic idea is to optimize ribs against an entire loading space rather than individual load cases one at a time. The loading space must be judiciously chosen in order to encompass all possible load cases and to take into account the load transfer mechanisms and possible special features of the rib under consideration such as stress concentration points, reinforcements and cutouts. The loading space used in th...
