This paper summarizes parts of a project that is concerned with an assessment of the damage potential of the ground motions recorded during the October 1, 1987 Whittier Narrows earthquake. Damage potential is defined here as the seismic demand imposed on building structures with due consideration given to representative structural response characteristics. The demand parameters considered in this study include strength demand, ductility demand, and energy and cumulative damage demands. The seismic demands are predicted from ground motion recordings, utilizing simplified elastic and inelastic bilinear SDOF structural models.
