Reliability of Serviceability and Strength of Deep Foundations Embedded in (p-y) Sand Below Water Table Subjected to Lateral Cyclic Loading

Piles are used in many engineering applications especially when we have weak soil that cannot support the proposed structure, also when we have a scour issue with the soil (especially in designing foundations for bridges), or when large uplift capacity is needed. In many engineering applications the piles are subjected to lateral loads as well as axial loads.;Reliability is a probabilistic method of analysis that provides consistent measurements for propagation of uncertainties and unifying framework for risk assessment. For this reason it is used instead of the factor of safety to provide a systematic account for the uncertainties and a rational procedure for the design.;Many design variables (uncertainties) affect the behavior of laterally loaded piles and the pile-soil system and their modeling. In reality when engineers are faced with uncertainties, they use a factor of safety to design the structure or a component, which is a conservative approach.
