ABSTRACT
Given the interest in performance-based earthquake engineering (PBEE) it is essential to have a design methodology that engineers can employ to accomplish the goals of PBEE. As noted by the Structural Engineers Association of California (SEAOC, 1999), the primary objective of PBEE is to design a structure to achieve predictable levels of performance under dened levels of seismic input, within denable levels of reliability. In order to accomplish these goals, it is essential that the design procedures used are capable of controlling structural performance. Such a requirement is the primary limitation of traditional force-based methods. Structural performance can be characterized by various parameters such as strains, curvature, rotations, displacement, dri, or ductility, which are of course all deformation
