A static pile load test was carried out on a 0.8-m-diameter steel pipe pile installed 21 m into a loose-to-medium sandy soil. The pile was driven into the soil. Selected load- displacement data are shown in the table on the next page.
(a) Determine the allowable load if the serviceability limit state is 12 mm.
(b) Is the maximum load the ultimate load? Justify your answer.
(c) Discuss some of the issues you would consider in the interpretation of the data.
