BEHAVIOUR OF LATERALLY LOADED PILES IN COHESIONLESS SOILS

Laterally loaded rigid piles in cohesionless soil

In this paper, limiting force profile for laterally loaded rigid piles in sand and is differentiated from the on-pile force profile, from which elastic-plastic solutions are established and presented in explicity expressioins. Nonlinear responses of the piles are characterized by slip depths mobilized from mudline and the pile-tip. At the states of tip-yield and rotation point yield, expression...

Development of p-y Curves of Laterally Loaded Piles in Cohesionless Soil

The research on damages of structures that are supported by deep foundations has been quite intensive in the past decade. Kinematic interaction in soil-pile interaction is evaluated based on the p-y curve approach. Existing p-y curves have considered the effects of relative density on soil-pile interaction in sandy soil. The roughness influence of the surface wall pile on p-y curves has not bee...

A Continuum-Based Model for Analysis of Laterally Loaded Piles in Layered Soils

An analysis is developed to calculate the response of laterally loaded piles in multilayered elastic media. The displacement fields in the analysis are taken to be the products of independent functions that vary in the vertical , radial and circumferential directions. The governing differential equations for the pile deflections in different soil layers are obtained using the principle of minim...

Dynamic behaviour of laterally loaded pultruted composite beams

This paper discusses a detailed study carried out on vibration characteristics of transversely loaded pultruted composite beams. A considerable discrepancy was noticed in the measured vibration of the transversely loaded beam and the calculated natural frequencies of the beam using Euler-Bernoulli beam theory. It has been observed that the natural frequencies of the beam were increased after la...
