The obtained spectra correspond to a given exceedence rate of a specific performance index characterizing the performance level for which the structures will be designed. The proposed formulation takes into account the non-linear behaviour of the structures and a given damage configuration under design conditions. This procedure involves the evaluation of the seismic hazard, necessary to define a seismic design level consistent with the performance based seismic design philosophy, using a large enough number of seismic records of several magnitudes, These records are simulated with an improved empirical Green function method. The statistics of the performance of a reference single degree of freedom system are obtained by using Monte Carlo simulation, assuming the seismic demand, the fundamental period and the strength of the structure as uncertain. With these results, the conditional probability that a structure exceeds a specific performance level is obtained. It is concluded that the proposed procedure is a significant improvement of other considered in the literature and useful research for the further development of uniform hazard spectra of use in the performance based seismic design and retrofit of structures.
