This generator of seismic signals takes into consideration earthquake and soil characteristics for a realistic depiction of ground motions. The proposed methodology uses genetic operators to transform the time series iteratively. Mimicking mating, natural selection, and mutation, the generator of genetic seismic signals, modifies the accelerations components of records considered good parents for producing successful individuals or new optimal signals that best fit the target conditions. The procedure is immediate and consistent with remarkable results in records that match a broad variety of target spectra with minimal deviation while conserving the geotechnical and seismological inherent qualities of the parents (recorded accelerograms).]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen En este trabajo se presenta un método original para el ensamblado de acelerogramas compatibles con un espectro objetivo preestablecido. El procedimiento se basa en un generador de señales sísmicas, el cual toma en consideración las características del evento sísmico y las condiciones del subsuelo para hacer una representación realista de los movimientos del terreno. Se utilizan operadores genéticos para transformar en forma iterativa los acelerogramas, imitando los procesos de apareamiento, selección natural y mutación. El generador de señales sísmicas genéticas, modifica los componentes de aceleración de los registros considerados buenos padres para producir individuos exitosos o nuevas señales óptimas que mejor se ajustan a las condiciones objetivo. El procedimiento es inmediato y consistente con resultados notables en registros que coinciden con una amplia variedad de espectros objetivo, con una desviación mínima y conservando las cualidades geotécnicas y sismológicas inherentes de los padres (acelerogramas registrados).]]></p></abstract>
