Axially - Loaded Centrifuge Pile Tests

Probabilistic Reliability Estimation of an Axially Loaded Pile

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...

Offshore anchor piles under mooring forces: numerical modeling

A parametric study was carried out to study the behavior of offshore anchor piles under mooring forces in dense sand using a three dimensional (3-D) finite element model (FEM). The Mohr–Coulomb plastic model has been used to model the soil, and has been calibrated based on the centrifuge tests discussed in a Ph.D. thesis (published by Ramadan in 2011). The selection of model parameters and comp...

Analysis Method for Laterally Loaded Pile Groups Using an Advanced Modeling of Reinforced Concrete Sections

A Boundary Element Method (BEM) approach was developed for the analysis of pile groups. The proposed method includes: the non-linear behavior of the soil by a hyperbolic modulus reduction curve; the non-linear response of reinforced concrete pile sections, also taking into account the influence of tension stiffening; the influence of suction by increasing the stiffness of shallow portions of so...

An alternative mechanism of pile failure in liquefiable deposits during earthquakes

This paper proposes an alternative mechanism of pile failure in liquefiable deposits during earthquakes. This failure mechanism, based on pile buckling, is formulated by back-analysing 14 case histories of pile foundation performance during earthquakes and verified using dynamic centrifuge tests. A new parameter, the slenderness ratio of a pile, is introduced to classify pile performance in liq...
