... main aspects related to axially loaded offshore piles in clay: methods to de.ermine the local ultimate skin friction and effects of cyclic loading on axial pile capacity. A new 'NGI-method' for determination of ultimate skin friction is described in detail. The method is primarily based on predicting...

... the southeast coast of Australia, generally provide relatively poor support for driven piles [1]. Drilled and grouted piles [2] which provide extremely high skin frictions, upwards of 400 kPa, are now the preferred solution, but are datively expensive. In an effort to improve the cost effectiveness of grouted...

... ABSTRACT API RP2A in its 14th edition (1984) recommends the use of an earth pressure coefficient of 0.8 for computing the tensile skin friction of an open ended pile driven into silica sands. In view of the impact of this recommendation on the design of North Sea piles driven into sands...

... to which cyclic loading degrades static skin friction depends upon the relative magnitudes of the sus- tained and cyclic load components and on whether the cycling is with respect to pilehead loads or to pilehead displacements (load or displacement con- trol). With all else being equal, damage to pile...

... can be explained by skin friction. The paper introduces a theory for calculating the hy- drodynamic part of the resonant heave damping. The theory is based on simple wake and momentum considera- tions. Comparison with the experiments shows that the theory predicts correctly the fact that the pressure...

... concerned the high values of unit skin friction estimated for the carbonatic origin stratum. Such values were based in Cone Penetration Test (CPT) and in laboratory test results using molded or undisturbed samples. In order to obtain reliable parameters, static pull-out tests were made, using 20" o.d. piles...
