The inelastic (design) spectra characterizing a seismic hazard are generally obtained by the scalingdown of the elastic (design) spectra via a set of response modiรฟcation factors. The component of these factors, which accounts for the ductility demand ratio, is known as the strength reduction factor

The paper deals with dynamic hysteretic oscillators without post-yielding hardening, called ideal elasto-plastic oscillators, subjected to white noise. They are characterized by the fact that they do not reach stationarity even though excited by stationary stochastic processes. A simpliยฎed solution
A new rule is presented to estimate strength-reduction factors in single-degree-of-freedom elastoplastic oscillators, in which reduction factors depend only on displacement elastic spectra, so they are not an explicit function of structural period. It is found that the proposed rule yields good resu
