PISA design model for monopiles for offshore wind turbines: Application to a stiff glacial clay tillByrne, Byron W. (author), Houlsby, Guy T. (author), Burd, Harvey J. (author), Gavin, Kenneth (author), Igoe, David J.P. (author), Jardine, Richard J. (author), Martin, Christopher M. (author), McAdam, Ross A. (author), Potts, David M. (author)Offshore wind turbines in shallow coastal waters are typically supported on monopile foundations. Although three-dimensional (3D) finite-element methods are available for the design of monopiles in this context, much of the routine design work is currently conducted using simplified one-dimensional (1D) models based on the p-y method. The p-y...journal article 2020

Burd, Harvey J. (author), Taborda, David M.G. (author), Zdravkovic, Lidija (author), Abadie, Christelle N. (author), Byrne, Byron W. (author), Houlsby, Guy T. (author), Gavin, Kenneth (author), Igoe, David J.P. (author), Jardine, Richard J. (author)This paper describes a one-dimensional (1D) computational model for the analysis and design of laterally loaded monopile foundations for offshore wind turbine applications. The model represents the monopile as an embedded beam and specially formulated functions, referred to as soil reaction curves, are employed to represent the various...journal article 2020

Liu, H. (author), Abell, J. A. (author), Diambra, A. (author), Pisano, F. (author)The modelling and simulation of cyclic sand ratcheting is tackled by means of a plasticity model formulated within the well-known critical state, bounding surface SANISAND framework. For this purpose, a third locus – termed the ‘memory surface’ – is cast into the constitutive formulation, so as to phenomenologically capture micro-mechanical,...journal article 2019
