TOLENTINO LOPEZ, Dante  y  RUIZ GOMEZ, Sonia E.. Evaluation of the Confidence Factor Considering Seismic Structural Damage Over Time. Ing. sísm [online]. 2015, n.93, pp.1-19. ISSN 0185-092X.

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.

Palabras llave : structural reliability; confidence factor; structural deterioration; cumulative damage.
