AUVINET-GUICHARD, Gabriel  and  RODRIGUEZ-REBOLLEDO, Juan Félix. Criteria for the design of friction piles subjected to negative skin friction and transient loads. Ing. invest. y tecnol. [online]. 2017, vol.18, n.3, pp.279-292. ISSN 2594-0732.

In this paper, an analysis of the behavior of an individual friction pile subjected to negative skin friction and transient loads (seism or wind) for typical stratigraphic and piezometric conditions of Mexico City lacustrine zone is presented. This analysis is performed using a two dimensional finite element model (2D FEM) and taking as a reference the field and laboratory researchs on individual point bearing piles developed by Fellenius (1998), Bozuzuk (1981) and Leung et al. (2004). A 2D FEM study of an internal pile within a pile group subjected to the weight of the structure and to negative skin friction is also presented. Finally, for the same conditions, 3D FEM analyses results are presented in order to assess the behavior of border and corner piles. Some criteria are proposed regarding design loads and negative skin friction estimation for internal, border and corner piles.
