000018838 520__ $$2eng$$aA methodology for the estimation of uniform vulnerability spectra (UVS) is proposed. The methodology includes two main stages: On the one hand, the zone seismicity definition in terms of exceedance rate of magnitudes, and on the other hand the computation of the exceedance probability of strength demand given an expected damage. The proposed methodology is the following: (1) computation of the exceedance rate of magnitudes, (2) characterization the seismic hazard in terms of ground motion records according to the considered magnitudes in the above step, (3) computation of damage spectra associated to several strength values for each ground motion record, (4) statistical and probabilistic treatment of the structural response in terms of damage index for each magnitude, strength value and structural period, (5) obtention of the expected lateral strength corresponding to a damage level given a structural period and a magnitude, (6) computation of lateral strength exceedance probability given a damage level for each structural period and magnitude (7) computation of exceedance rate of lateral strength given a damage level and a structural period (8) construction of the UVS by selecting, in several exceedance rate of lateral strength curves associated to several structural periods, the lateral strength value that has the same given exceedance rate. Finally is presented an example of proposed methodology applied to a hypothetic single seismic source.
