Several attempts have been carried out to understand the foundation failures during earthquake type of transient loading and it has been found that the interaction effect between soil and foundation is one of the important aspects need to be considered in the analysis and design. In this regard a literature survey has been carried out on frame structures supported on pile foundation which is in...

An open ended pipe pile can become plugged when sufficient frictional resistance is developed by the inner soil cylinder within the pile (soil plug), thereby preventing further intrusion of the soil into the pile. When plugging occurs in an impact driven pipe pile, a complex interaction between the pile and soil plug takes place, causing the propagating stress wave to undergo an abrupt change. ...

ABSTRACT This study presents an investigation of the interaction effect of one loaded pile on a neighboring pile under transient dynamic loadings. Analyses are carried for non homogeneous soils. The hybrid boundary element formulation is used to represent boundary integral representation of soil domain and pile equations represented by linear structural components. The formulation is presented ...

Analytical solutions are developed for harmonic wave propagation in an axially or laterally oscillating pile embedded in homogeneous soil and excited at the top. Pilesoil interaction is realistically represented through a dynamic Winkler model, the springs and dashpots of which are given values based on results of finite element analyses with the soil treated as a linear hysteretic continuum. C...

Previous case histories have shown that soil liquefaction severely damaged many structures supported on pile foundations during earthquakes. As a result, evaluating the potential for instability is an important consideration for the safe and resistant design of deep foundation against earthquakes. In this study, the liquefaction susceptibility of saturated sand interacting by single concrete pi...

The past earthquake study conducted on the foundation system (soil and foundation) reveals that the interaction of soil and foundation plays a major role in the response of superstructure. In this regard a literature survey has been carried out on frame structures supported on pile foundation which is in contact with more soil mass as compared to the other type of foundation system. In this res...

A quasi-three-dimensional finite element method of analysis is proposed for the dynamic response analysis of pile foundations that is computationally feasible for practical applications. The method uses a simplified three-dimensional wave equation for describing the dynamic response of the soil. The response of the pile foundation is computed directly without having to use pile–soil–pile intera...

A new efficient and accurate hybrid reliability method is proposed to estimate risk of an axially loaded single pile considering pile-soil interaction effect. Uncertainties associated with all the design variables are considered appropriately. It intelligently integrates the concepts of the response surface method, the finite difference method, the first-order reliability method, and an iterati...

This article presents a numerical model and analyses of the dynamic response structures supported by groups piles. The uses finite element discretization to represent arbitrarily-shaped structures, coupled finite-boundary scheme embedded pile group. properly takes into account energy transferred from structure piles between through soil, so that effect pile-soil-pile interaction in can be studi...
