El factor de confianza y su correspondiente nivel de confianza se expresan mediante ecuaciones matemáticas cerradas. La formulación se desarrolla de acuerdo con el formato de diseño basado en factores de demanda y capacidad estructural. Las expresiones propuestas se extienden a partir de la formulación original que no considera el deterioro en el tiempo propuesta por Cornell. El criterio propuesto se aplica a un edificio de concreto reforzado de 10 niveles ubicado en suelo blando con características similares al sitio de la Secretaría de Comunicaciones y Transportes en la Ciudad de México.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT: A criterion to evaluate the confidence factor that takes into account the deterioration of the structural capacity and the increment of the seismic demand at the end of a time interval is proposed. The confidence factor and its confidence level are expressed by means of closed-form mathematical equations. The formulation is made in accordance with the Demand and Capacity Factor Design Format. The simplified closed-form expressions are based on the original formulation proposed by Cornell where the structural deterioration over time is not considered. The proposed criterion is exemplified by means of the analysis of a 10-story building located on soft soil with characteristics similar to those of the site of the Ministry of Communications and Transports in Mexico City.]]></p></abstract>
