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...

The use of embedded pile elements provides a convenient approach that may save significant modelling time in the simulation of piled foundations. A back-analysis of an Osterberg-cell (O-Cell) load test on a 45 m long pile is presented to illustrate some of the advantages of using structural embedded elements. Comparisons with other modelling approaches for piled-raft foundations have showed goo...

Approved for public release; distribution is unlimited. 1. Purpose. This manual provides information, foundation exploration and testing procedures, load test methods, analysis techniques, allowable criteria , design procedures, and construction consideration for the selection, design, and installation of pile foundations. The guidance is based on the present state of the technology for pile-so...

An existing riverine platform in Egypt, together with its pile group foundation, is analyzed under environmental loads using 3D FEM structural analysis software incorporating soil-pile interaction. The interaction between the transfer plate and the piles supporting the platform is investigated. Two connection conditions were studied assuming fixed or hinged connection between the piles and the ...

Strain wedge (SW) model formulation has been used, in previous work, to evaluate the response of a single pile or a group of piles (including its pile cap) in layered soils to lateral loading. The SW model approach provides appropriate prediction for the behavior of an isolated pile and pile group under lateral static loading in layered soil (sand and/or clay). The SW model analysis covers the ...
