Fictitious pile method for fixed-head pile groups subjected to horizontal loading

Harmonic Response of Pile Groups to Dynamic Loading

A completely general method of analysis for three-dimensional raked piles under harmonic excitation is discussed. The piles have been represented by a three-dimensional frame structure and the soil has been represented by a boundary element discretization scheme. A computer program has been written which carries out this analysis and produces a group stiffness matrix that can be included as a f...

Torsional Pile Subjected to Transient Loading in Viscoelastic Poroelastic Medium

Considering viscoelastic saturated soil, The transient dynamic response of an elastic pile is studied. The pile-soil system is divided into thin layers, the control equations of the soil are solved respectively by using Laplace transform. Considering the mixed boundary-value conditions at the interface of pile and soil, expression is derived to describe the relationship between the inner force ...

Interpretation of static pile loading test results and application for design of pile groups

Recent major bridge projects in the Greater Vancouver Area showcase the experience of local geotechnical engineers. Large static pile loading tests have been carried out on a number of these projects including the Pitt River Bridge, Golden Ears Bridge and Port Mann Bridge projects. This paper briefly discusses different analytical approaches to load test interpretation and reviews the approach ...

Static and Dynamic Lateral Loading of Pile Groups

Sensitivity analysis of pile-founded fixed steel jacket platforms subjected to seismic loads

The sensitivity of the seismic response parameters to the uncertain modeling variables of pile-founded fixed steel jacket platforms are investigated using the Tornado diagram and the first-order second-moment techniques. The effects of both aleatory and epistemic uncertainty on seismic response parameters have been investigated for an existing offshore platform. The sources of uncertainty consi...
