Descripción
A hybrid approach to obtain the expected seismic action combining regional- and lo-cal-scale information is presented and applied to certain sites of Almeria and Granada (Southern Spain). A probabilistic seismic hazard assessment on rock conditions at re-gional scale is performed. Uniform hazard spectra (UHS) at capital cities are obtained, and hazard is disaggregated to infer controlling earthquakes for different target mo-tions. These results, combined with the data of site characterization, provide a set of specific response spectra (SRS) for different controlling magnitude-distance pairs and the UHS including soil conditions. These spectra are first-order approximations to ex-pected seismic actions required in local earthquake risk assessments and earthquake-resistant design. In addition, fundamental periods of different buildings are measured at certain places. Moreover, areas where period-dependent resonant effects are likely to occur are identified. A discussion is set up to investigate which response spectrum is more suitable and/or conservative, depending on predominant soil periods and the fundamental period of the structure. Two examples from sites at the cities of Almeria and Granada are used to illustrate this approach.
