... and compared to flow patterns around pile groups. In the consideration of current induced flow patterns along the jacket structure it becomes evident that a flow around a jacket structure cannot easily be approximated by direct transfer of knowledge from in-line pile groups. For blockage factors A f /A t...

... Abstract Aimed at the time effect, group effect and difference between negative skin friction (NSF) on pile in sand and that in clay, a series of model tests include single pile tests and pile group tests were carried out. The test results indicate that the NSF on pile increases...

... ABSTRACT In the present study, a series of experiments on the scour depth around single piles and pile groups were conducted. The scour depths around single piles are plotted against flow velocity, and they are compared with the values predicted with HEC-18. The experimental scour depths...

... ABSTRACT The interaction of non-breaking waves and pile group-supported offshore structures is studied by means of extensive and systematic large-scale laboratory tests performed in the Large Wave Flume (GWK) of the Coastal Research Centre (FZK) in Hannover, Germany. Three different...

..., the p y curve of a pile group is determined by applying the p-multiplier to the p y curve of a single pile. The p-multiplier for static loading conditions has been suggested by many researchers (US Army, 1993; Reese et al., 1996; AASHTO, 2000; Reese and Van Impe, 2001; WSDOT, 2002). The p-multiplier...
