Abstract: Software for nonlinear analysis of a single pile response based on load transfer method is presented in this paper. Different load transfer functions such as a hyperbolic model and a softening model can be adopted in the present software to capture the relationship between unit skin friction and pile-soil relative displacement and the relationship between unit tip resistance and pile tip displacement. In the present software, the single pile is divided into different segments to consider layers of soil, and the influence of the groundwater level on the single pile response can be taken into account. The single pile response derived from the present software is generally in good agreement with the field-observed behavior. The proposed software is efficient, and suitable for the analysis of nonlinear response of a single pile.

Key words: single pile, nonlinearity, load transfer functions, multilayered soils
