| description | The subject of reliability-based design for North America is reviewed. The objective of probabilistic design using First order Second moment methods is described. These Methods are based on the concept of safety index, from which the probability of failure, Pf, can be estimated. Calibration procedures for the design equations are discussed. Load factors specified by different codes for usual loading combinations are presented, as well as the resistance-reducing factors. One argument in favor of probabilistic design is that it provides a quantitative measurement of the safety of structures. However, quite often, the differences between observed and predicted failure rates are substantial. Some of the reasons for these discrepancies are presented. Results from the literature indicate that the serviceability requirement of the current codes could be insufficient in terms of reliably predicting the functional behavior of modern structures. |

Se revisa el tema del diseño basado en la confiabilidad en Norte América. Se describe el objetivo del diseño probabilístico usando métodos de primer orden y Segundos Momentos, basados en el cálculo del índice de confiabilidad, a partir de cual se puede estimar la probabilidad de falla Pf. Se discuten los procedimientos de calibración de las ecuaciones de diseño. Se presentan los factores de carga especificados por algunos reglamentos para combinaciones de carga usuales y se incluyen los factores de reducción de resistencia correspondientes. Un argumento a favor del diseño probabilístico es que provee una medida cuantitativa de la seguridad. Sin embargo, las diferencias entre las tasas observadas de falla y las predichas a menudo son substanciales. Se comentan algunas de las razones que podrían explicar dichas discrepancias. Se argumenta que los requisitos de servicio de los códigos actuales podrían ser insuficientes para garantizar un comportamiento funcional de las estructuras modernas.
