Resumen:

A methodology to obtain design accelerograms in sites affected by several seismic sources and nonlinear site effects is proposed. A site in Mexico City is used as an example. A probabilistic seismic hazard analysis (PSHA) is evaluated incorporating nonlinear soil-site effects. A method of disaggregation probabilistic seismic hazard assessment (DPSHA) is applied to determine the most probable magnitude and distance of certain seismic events that can generate a selected seismic intensity associated to an exceedance rate. To generate the motions, we use the empirical Green's functions simulation method modified by attenuation and geotechnical data. Finally, we propose the minimum number of design ground motions and for which structural periods the spectral ordinates should be used so that the response of the expected motion fits the uniform hazard spectrum.
