“…This topic has received much interest in recent times from researchers working in the area of earthquake engineering [8,12,13]. Both Nogami et al [14] and Allotey et al [11] give a good overview of the development of general nonlinear soil-pile interaction models for dynamic applications.…”

“…The model is shown to be capable of producing accurate results with a fraction of the computational time required by the full 3-D FE model. Boulanger et al [13] evaluates the performance of a dynamic BNWF model against the results of a series of dynamic centrifuge model tests, where two pile supported structures are founded in a soil profile comprising soft clay overlying sand and subjected to nine earthquake shaking events. A parametric study is undertaken to assess the sensitivity of the analysis results to the chosen dynamic p-y parameters and site response calculations.…”

“…For small-strain applications, a unique value of stiffness, either the small-strain shear (G 0 ) or Young's (E 0 ) moduli can be used to model the elastic soil response. This parameter is also one of the key inputs required to model the initial stiffness response when largestrain nonlinear dynamic response is modelled (see [13]). The primary issue considered in this paper is the specification of an initial stiffness parameter that accurately reflects the in-situ small-strain stiffness of the combined soil-pile system.…”

This paper presents a simplified nonlinear sway-rocking model as a preliminary design tool for seismic soil-structure interaction analysis. The proposed model is intended to capture the nonlinear load-displacement response of shallow foundations during strong earthquake events where foundation bearing capacity is fully mobilized. Emphasis is given to heavily-loaded structures resting on a saturated clay half-space. The variation of soil stiffness and strength with depth, referred to as soil non-homogeneity, is considered in the model. Although independent springs are utilized for each of the swaying and rocking motions, coupling between these motions is taken into account by expressing the load-displacement relations as functions of the factor of safety against vertical bearing capacity failure (FSv) and the moment-to-shear ratio (M/H). The simplified model has been calibrated and validated against results from a series of static push-over and dynamic analyses performed using a more rigorous finite-difference numerical model. Despite some limitations of the current implementation, the concept of this model gives engineers more degrees of freedom in defining their own model components, providing a good balance between simplicity, flexibility and accuracy.

This article summarizes design methods for pile foundations subjected to axial and lateral loading. It addresses the main factors that need to be considered in a basis of design, focusing on driven steel pipe piles, which are almost universally used in offshore practice. The response of less frequently used piles grouted into stronger sediments, such as calcarenite and other weak rock, is also considered. Modern design approaches based on data from cone penetration testing are outlined. For lateral response, the main focus is on load transfer methods. Reference is also made to elastic solutions that can provide a useful approach for operational loading, particularly for large diameter monopiles such as are used in the offshore wind industry. Just as for axial loading, the potential use of cone penetration data as the basis for deriving lateral load transfer curves is also discussed. Underlying principles of the effects of cyclic loading are presented. The article concludes with brief comments on scour and seismic design, two other considerations for the design of offshore piles.
