Performance Reliability of Offshore Piles
Summary by Limin Zhang: This paper describes an assessment of the bias, error and reliability associated with capacities and performances of axially and laterally loaded piles, designed according to API recommended guidelines. The major sources of uncertainties affecting axial and lateral performances of piles in clay and sand are identified first, including errors in pile capacity prediction method, errors in pile load testing, total effect of uncertainty in soil parameters, and total effect of other factors not normally considered. These uncertainties are then assessed using available field and laboratory test data. Subsequently, these individual components of uncertainties are integrated through a simple probability model for further reliability evaluation. Results from this research will help direct future research efforts for reducing major uncertainties affecting pile performances, and assist designers to better assess differences between various editions of API-RP2A recommended guidelines. This paper was recognized at the ASCE OTC Hall of Fame in 2013. Prof. Wilson Tang is among the very few individuals who were honored twice. His other paper that was honored at the ASCE OTC Hall of Fame in 2014 was “Case Study of Offshore Pile System Reliability.”
