DYNAMIC BEHAVIOR OF CURVED PILES

The paper presents an analytical model and associated computer program which is developed to investigate the dynamic behaviour of curved pil es embedded in a homogeneous elastic half-space and subjected to force d harmonic vertical vibration, wherein the movement of piles in the ax ial and lateral directions are considered. The analysis accounts for a soil-pile interaction in a simplified way and predicts the response o f such foundations. Equivalent stiffness and damping parameters of pil e in longitudinal and horizontal directions have been studied and typi cal results have been presented. A parametric study of the dimensionle ss amplitudes in longitudinal and lateral directions is also presented . The directions are found to depend on the frequency of vibrations, s lenderness ratio and curvature of pile. Analytical results are compare d with experimental ones.
