A better understanding of the soil-pile interaction for closed and open ended piles is extremely important for an accurate evaluation of the existing design methods. In this paper, the results of a series of full scale static and dynamic load tests carried out on pipe piles are presented. The tests are performed on twenty trial pipe piles, sixteen of them are open ended and the remaining are closed ended. The main goal of this paper is to assess the behavior of pipe piles. The results of pile load tests on open ended pipe piles are compared to those on closed ended ones. Such comparisons are carried out in case of static tests and dynamic tests. Furthermore, the calibration between the static and dynamic tests results are carried out. A detailed interpretation of the results is also presented to show the pile capacities in the field. Furthermore, pile capacities using the static axial capacity methods are estimated. The comparison of the field capacities and the calculated capacities sheds light on the adequacy of the popular formulas used to estimate pile capacity during design.
