Soil‐pile interaction in horizontal vibration

Earthquake Engineering & Structural Dynamics, 1977
AbstractInteraction between soil and an elastic pile vibrating horizontally is theoretically examined. The soil is modelled as a linear, viscoelastic layer overlying rigid bedrock. The pile is assumed to be vertical and point bearing. This study utilizes the definition of soil resistance presented in a preceding paper.1 A direct solution is developed ...

An Analytical Expression for the Nonlinear Evaluation of the Soil-Pile Interaction

Art of Foundation Engineering Practice, 2010
Pile foundations are commonly used for many types of structures and vertical and/or lateral loading design considerations are very important because the performance of the piles significantly influences the integrity of the structures supported by them. Current design methods of pile foundations often involve an estimation of a constant stiffness as an

SEISMIC SOIL-PILE INTERACTION - INFLUENCE OF SOIL INELASTICITY

Proceedings of the 4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2013), 2014
The main purpose of this study is to investigate the influence of soil p-y nonlinearity in soil–pile–structure kinematic and inertia interaction. Within this context, a beam on nonlinear Winkler foundation model is adopted based on the Boundary Element Method (BEM), accounting for the effects induced by geometrical nonlinearity, rotary inertia and ...

Numerical analysis of kinematic soil—pile interaction

AIP Conference Proceedings, 2008
In the present study, the response of singles pile to kinematic seismic loading is investigated using the computer program SAP2000@. The objectives of the study are: (1) to develop a numerical model that can realistically simulate kinematic soil‐structure interaction for piles accounting for discontinuity conditions at the pile‐soil interface, energy ...

Continuum Mechanics of Lateral Soil–Pile Interaction

Journal of Engineering Mechanics, 2004
A rigorous mathematical formulation is presented for a flexible tubular pile of finite length embedded in a semi-infinite soil medium under lateral loading. In the framework of three-dimensional elastostatics and classical beam theory, the complicated structure-medium interaction problem is shown to be reducible to three coupled Fredholm integral ...

Dynamic soil–pile interactions for machine foundations

International Journal of Geotechnical Engineering, 2016
To achieve the satisfactory performance of a machine foundation, the dynamic amplitude should be limited to a few micrometres. In using piles for the foundation, the interaction of the pile with the surrounding soils under vibratory loading will modify the pile stiffness and will generate damping.

Soil-Pile-Superstructure Interaction in Liquefiable Sand

Transportation Research Record: Journal of the Transportation Research Board, 1997
Soil-pile-superstructure interaction in liquefiable sand is evaluated using dynamic centrifuge model tests and pseudostatic p-y analyses. Select recordings from a recent centrifuge test are presented to illustrate typical behavior with and without liquefaction in an upper sand layer.

Soil–pile thermal interactions in energy foundations

Géotechnique, 2016
In this technical note, the results of a set of simplified numerical analyses are presented. The analyses were undertaken in order to examine the validity of a descriptive framework that was previously proposed to illustrate the behaviour of thermally activated piles and to highlight the potential limitations of some analytical methods that are being ...

Layered soil‐pile‐structure dynamic interaction

Earthquake Engineering & Structural Dynamics, 1981
AbstractThis paper is concerned with the dynamic interaction between soil, pile and structure when subjected to harmonic excitation at the base rock level. The structure to be analysed is an isolated tall bridge pier with deep group pile foundation. The dynamic substructure approach is taken, dealing first with the pile‐footing substructure and the ...

Soil-Pile Structure Interaction during Earthquakes

Geotechnical Engineering for Transportation Projects, 2004
Seismic soil-pile structure interaction (SSPSI) is a complex process involving several, simultaneously occurring and, sometimes compensating phenomena. To better appreciate SSPSI, the physical processes that occur when a pile supported structure is seismically loaded are first categorized into far-field effects, near field effects, and inertial effects.
