Abstract

The performance of a single barrette subjected to lateral load applied at its top is presented in this paper using three-dimensional finite element analyses based on Midas GTS program. Nonlinear behaviors of the barrettes buried in clayey and sandy soils were monitored using Mohr-Coulomb soil model. Performances of the barrettes with lateral loads applied in both longitudinal and transverse directions were examined. Displacements of the barrettes affected by stiffness and strength of the soils were obtained and normalized with the nominal length of the barrette. The criteria for long and rigid barrettes with loads in different directions were suggested. For the barrettes with loads in the transverse direction, the conventional analytical solution suggested by Chang for a single pile was found applicable to the predictions. In such case, the equivalent diameter calculated from moment of inertia of the barrette was found more adequate to be used in the analytical solution. Results of this study can help the engineers to understand more about the barrette performance under lateral loads.
