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...

Raft and Pile Foundations under Cyclic Loading

The paper presents typical phenomena which can occur due to cyclic loading in granular soil. Numerical analysis with different material laws shows the challenges to simulate the ground behaviour realistically. Results of numerical analysis by means of the Finite-Element-Method are presented and the limitation of material laws discussed.

A comparative study on pile group and piled raft foundations (PRF) behavior under seismic loading

Study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. The process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. By means, ABAQUS software was applied for the finite elem...

Use of Embedded Pile Elements in 3d Modelling of Piled-raft Foundations

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...
