Abstract (EN): This paper aims to show reliability concepts for axial pile foundations' design and safety aspects, revealing that reliability analysis do not imply a significant increased effort when compared to the traditional design methodologies. In fact, calculations using reliability concepts provide very useful information, such as the uncertainty that mostly influence the probability of failure. Therefore, the most used reliability methods, FORM and MCS, are here presented and used to evaluate the safety of the bearing capacity of an axial bored pile considering the geotechnical uncertainties and different load values. For the application example presented, the physical uncertainties of actions, the inherent soil variability and model error (pile's resistance) were determined by experimental in situ tests (SPT) or collected from bibliography. © 2014 Taylor & Francis Group, London.
