Dragload_Downdrag_2.pdf: The basics of the Fellenius Unified Pile Design of Capacity, Negative Skin Friction (Dragload and Downdrag), and Settlement. If you go to Fellenius's website he has several papers on downdrag, which occurs in all soils and only effects the structural capacity of the pile. It is the frictional capacity of the soil above the neutral plane. 2004-12-01 · 6) B.H.

Fellenius (1988) identified changes in effective stress during reconsolidation of the soil after pile construction as a possible cause of negative skin friction development.Fellenius (1969), Leung at al. (1991), and Leifer (1992) showed that a transient (live) load will not coexist with a In 2002, he was conferred the Distinction of Fellow of the Engineering Institute of Canada “in Recognition of Excellence In Engineering and for Services to the Profession and to Society”, in 2010, he was the Osterberg Lecturer at the 2nd Annual Osterberg Memorial Lecture and Dinner, in 2012, ASCE published a Special Geotechnical Publication “Honoring Bengt H. Fellenius and Role of Full-scale Testing in Foundation Design”, in 2012, he was elected Honorary Member of the Swedish Ongoing field studies at MnDOT support that dragload and downdrag effects are far more common than previously appreciated so common that the effect has been observed to - some degree on every instrumented pile performance project.

F-4 Locally Adopted (MnDOT Practice) Dragload (DD) Load Factor for Neutral Plane I am uncertain about how to construct the "resistance curve" in Fellenius's method for determining the location of a the neutral plane for piles subjected to downdrag (see attached). At point A, the value is R t + Sum of R S from A to B. Fellenius (1972) developed the NP method to estimate drag load and downdrag for piles in clay.
