Lateral deflection of horizontally loaded rigid piles in elastoplastic medium / Ernesto Motta in Journal of geotechnical and geoenvironmental engineering, Vol. 139 N° 3 (Mars 2013) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 139 N° 3 (Mars 2013) . - pp. 501-506 Titre : Lateral deflection of horizontally loaded rigid piles in elastoplastic medium Type de document : texte imprimé Auteurs : Ernesto Motta, Auteur Année de publication : 2013 Article en page(s) : pp. 501-506 Note générale : geotechnique Langues : Anglais (eng) Mots-clés : piles;  shafts;  rigidity;  design;  lateral  loads;  deflection;  elastoplasticity Résumé : This paper deals with the design of rigid piles under lateral load. In many practical situations pile displacements may be the limiting factor in the design; thus, an allowable displacement analysis instead of an allowable stress analysis may be more appropriate in the foundation design. A nonlinear elastoplastic closed-form solution for the evaluation of the response of rigid piles under lateral load is presented. The derived equations allow determining the lateral displacement and load distribution for a given combination of the applied forces, H0 and M0, at the pile head. The approach can be applied either for cohesive or cohesionless soils. For greater generality, the solution has been given in nondimensional form. A comparison with the Broms solution for a free rigid pile in cohesionless soil is also presented. Comparisons with experimental results show that the proposed approach may fit in a reliable way the nonlinear load-displacement response of a free rigid pile.
