ABSTRACT: The goal of this paper is to compare the overall level of safety aimed at by geotechnical design codes from various locations around the world. In particular, the National Building Code of Canada (NBCC), the Canadian Highway Bridge Design Code (CHBDC), the American Association of State Highway and Transportation Officials (AASHTO), the Eurocode (EC), and the Australian Standards (AS) design codes are compared. The comparison is made by estimating a global factor of safety as a function of load and resistance factors, characteristic load and resistance biases, and dead to live load ratio, specifically for the shallow foundation bearing capacity ultimate limit state. The results of the paper can be used to aid in the calibration of the next generation of reliability-based geotechnical design codes of practice around the world.
RÉSUMÉ: Le but de cet article est de comparer le niveau global de sécurité visé par les codes de conception géotechniques provenant de différents endroits à travers le monde. En particulier, le National Building Code du Canada (NBCC), le Canadian Highway Bridge Design Code (CHBDC), l'American Association of State Highway et Transportation Officials (AASHTO), l'Eurocode (EC), et les Australian Standards (AS) de conception des codes sont comparées. La comparaison est faite par l'estimation d'un facteur global de la sécurité en fonction des facteurs de charge et de résistance, caractéristiques des préjugés de charge et de résistance, et morts pour vivre rapport de charge, en particulier pour le palier fondation d'utilité publique peu profonde limite la capacité ultime. Les résultats du document peut être utilisé pour aider à l'étalonnage de la prochaine génération de la fiabilité des codes axés sur la conception géotechniques de la pratique partout dans le monde.
