The main objective of this research was to study the effect of pile length on total pile resistance driven into dense sandy soil. Axial compression tests were performed on closed-ended steel pipe piles. The calculated resistance’s using American Petroleum Institute method and Alawneh proposed approach are compared with measured pile resistances. A relationship between the volume of displaced soil and ultimate pile resistance is proposed. A selection of five methods of estimating the failure load in pile loading tests is examined. From the results of the study of 15 pile loading tests, a method is proposed for estimating failure loads for driven pile in sandy soil.
