In the design of a structural system based on capacity, selected ductile members are permitted to yield during strong motion, to form an energy-dissipating plastic mechanism that protects the remaining elements from yielding. This paper shows that this design approach can be extended to consider the soil that interacts with the structure as a ductile element in the strength hierarchy chain. In the paper, this concept is applied initially to flexible earth retaining structures, showing that this strategy can be readily implemented in the design with the objective of protecting the structural elements of the system. The second part of the paper deals with the foundation of structures, exploring the possibility that during a strong earthquake their bearing capacity is mobilised. The potential consequences of this approach are discussed with the aid of either idealized or actual structures, including the cases of a reinforced concrete frame and of a suspension bridge.
