Abstract
A new empirical scheme for simulating the nonlinear point resistance response of single piles in cohesionless soils is proposed. The pile‐soil system is idealized by using a one‐dimensional finite element technique. The shear resistance response along the pile shaft is found by using the concept of t‐z curve proposed by Kraft et al., whereas the new method is used to define the tip resistance response or the so‐called p‐z curve. A generalized Ramberg‐Osgood model is utilized to simulate the nonlinear t‐z and p‐z curves. To check the validity of the method, four examples involving field and laboratory tests on piles in sands are considered. The comparisons between the finite element predictions, and the laboratory and field observations, show good correlation. The results are relevant to a specific class of problems that involve submerged or dry sand, long piles, and a constant value of the lateral earth pressure coefficient.
