AbstractPile resistance is composed of skin friction and end bearing. One method of determining the two components is to conduct loading and pulling tests and is based on the simple assumption that skin friction on the pile shaft remains unchanged in the two tests. The validity of such an assumption is studied using a finite element analysis. The paper describes the finite element formulation, which involves the use of joint elements to permit slippage at the soil-pile interface. The soil is characterized by nonlinear, inelastic behaviour. a parametric study is conducted to investigate the effects of initial stress distribution, loading history, and difference in mechanical behaviour of the soil and pile material. The practical implications are discussed.
