“…Varying degrees of bent were adopted for both friction and end-bearing piles. Khan and Pise (1997) presented an analytical model to investigate the dynamic behavior of curved piles embedded in a homogeneous elastic half-space and subjected to forced harmonic vertical vibration, wherein the movement of piles in the axial and lateral directions was considered. Maithili (2006) conducted experiment on the model single piles/pile group with a single bent pile in the group(2 9 1 and 2 9 2) embedded in homogeneous sand subjected to compressive loads.…”

In this paper an analytical method has been proposed to predict the net ultimate uplift capacity of the single bent pile and pile group with a bent embedded in sand considering arching effects. Arching develops due to relative compressibility of sand relative to pile which activates the soil-pile friction. The method takes into consideration the embedded length (L), diameter of the pile (d), bent angle, surface characteristics of pile, group configuration, spacing of the pile group and the soil properties. Log spiral failure surface with parabolic arch shape was assumed in the analysis. Theoretical investigation for uplift capacity was been carried out for the single bent pile and group of pile (2 9 1, 2 9 2) embedded in sand. The variable used in the analysis were embedded length to pile diameter (L/ d = 15, 20 and 25), spacing in the group (3d, 4d and 6d) and angle of bent (6°, 14°and 20°). Typical charts for evaluation of net ultimate uplift capacity for pile groups are presented through the figures.Comparison of theoretical results shows good agreement with established experimental results.

Abstract-In this study, the in plane vibrations of cracked circular curved beams is investigated. The beam is an Euler-Bernoulli beam. Only bending and extension effects are included. The curvature is in a single plane. In plane vibrations is analyzed using FEM. In the analysis, elongation, bending and rotary inertia effects are included. Four degrees of freedom for in-plane vibrations is assumed. Natural frequencies of the beam with a crack in different locations and depths are calculated using FEM. Comparisons are made for different angles.
