Today there is a concerted international focus on reduction of seismic risk through assessment and rehabilitation programs to upgrade buildings that are deemed inadequate with regards the level of the seismic protection they provide to the public. Establishing an optimum retrofit strategy is a complex procedure. Several alternative retrofit strategies may be possible for a specific project which should be evaluated before proceeding to the application of the most efficient solution. The objective of this paper is to present a retrofit assessment procedure that relates the characteristics of the intervention method to the demand imposed by the earthquake. A new type of spectrum representation is developed, the Retrofit Design Spectra (RDS), where the demand is related to the key design parameters of the intervention method. The methodology utilized for the derivation of the RDS is based on the Capacity Spectrum Method (ATC 40), as later modified in ATC 55/FEMA 440, where the Capacity Curve is described by relationships for global intervention methods that are parameterized in terms of fundamental response quantities. The proposed spectra provide a direct insight into the complex interrelation between the characteristics of the intervention method and the implications of retrofitting on demand. Alternative retrofit solutions are thus assessed in an efficient way that clearly links supply to demand.
