Abstract
Recently, the use of barrette pile has remarkably increased for high-rise building and bridge foundations. However, relatively few studies have been made for analyzing barrette pile behavior by considering shear load transfer on interface between pile and soils. Therefore, in this paper, an empirically derived equation is proposed. This equation correlates the load transfer curve of barrette piles with the N value from field standard penetration test based on full-scale load tests. The results from all procedures are presented. In addition, the effect of interface on pile-soil is evaluated using 3-D non-linear finite element method and verified with the field data.
