Seismic performance-design of soil structures and foundations have emerged as a basis for overcoming the limitations present in conventional seismic design. Conventional seismic design is based on pseudo-static method in a limit equilibrium state. In seismic performance-design, deformations ground and foundation soil, and the corresponding structural deformation and stress states are used as key design parameters. This paper presents a systematic, consistent framework for seismic performance-design based on the review of the case histories of seismic damage to soil structure and foundations. In particular, the paper proposes to introduce acceptable damage levels based on direct and indirect losses due to seismic damage to the structures. The paper also presents choice of analysis methods based on performance grades.
