Generalized nonlinear model describing softening and hardening behaviors of skin friction for axially loaded piles
https://orcid.org/0000-0001-6254-6242
Abstract This study proposes a new generalized nonlinear (GN) model to provide a continuous describing in the whole nonlinear regime of load-transfer curves, including both softening and hardening phenomenon. The applicability of the proposed GN model is verified by comparing the calculated relation between the skin friction and relative pile-soil displacement of axially loaded piles with measurements and those calculated by existing nonlinear softening models. Moreover, the proposed GN model is implemented in a finite element program for settlement analysis of axially loaded piles. The results indicate that the proposed GN model can be considered as a generalization of a hyperbolic model and an existing generalized nonlinear softening model and is expected to cover a wide range of variations in skin friction-displacement data of axially loaded piles.
