—This paper examines the spectrum of inelastic
displacement ratio (IDR) for structures subjected to near-fault
earthquakes. IDR can be defined as the ratio of the maximum
inelastic to the maximum elastic displacement of a structure
and allows the computation of its maximum inelastic
displacement directly from the corresponding elastic
counterpart. Extensive parametric analyses are carried out to
obtain empirical expressions for this ratio, in terms of the
period of vibration and ductility demands.
