Abstract
This paper presents the results of analyses of barrette piles. For this purpose models of barrette pile were developed in MIDAS GTS software, which is based on finite element method. Soil model was developed by Mohr–Coulomb and pile as linear elastic model. Various shapes of barrette, with similar cross-section area, viz., 1.5, 3 and 4.5 m2 were considered for analysis and their lateral and uplift capacities were determined for different relative densities of soil. The capacities of barrette piles were compared with those of circular pile with the same cross-section area, and the improvement in lateral and uplift capacities of barrette piles was determined. Results indicate that the barrette piles have higher lateral and uplift capacities and percentage increase is in the range of 100–1300% as compared to circular pile. Also, cruciform shape barrette pile has higher lateral and uplift capacity among other shapes of barrette.
