Effect of cracking on the response of pile test under horizontal loading / Emilios M. Comodromos in Journal of geotechnical and geoenvironmental engineering, Vol. 135 N° 9 (Septembre 2009) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 135 N° 9 (Septembre 2009) . - pp. 1275–1284 Titre : Effect of cracking on the response of pile test under horizontal loading Type de document : texte imprimé Auteurs : Emilios M. Comodromos, Auteur ; Mello C. Papadopoulou, Auteur ; Ioannis K. Rentzeperis, Auteur Année de publication : 2009 Article en page(s) : pp. 1275–1284 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : PilesCrackingThree-dimensional  analysisPile  testsHorizontal  loads Résumé : Capacity-based design of structures limits the soil-structure interaction mechanism to the determination of the bearing capacity of a pile group. However, in many cases the criterion for the design of piles to resist lateral loads is not the ultimate lateral capacity but the deflection of the piles. Many procedures exist for estimating the response of single piles and pile groups under lateral loading, ranging from application of empirical relationships and simple closed-form solutions to sophisticated nonlinear numerical procedures. With the aim of investigating the effect of cracking, disregarded by most of the above-mentioned methods, a three-dimensional (3D) nonlinear analysis that accounts for cracking is presented. Response prediction correlates well with the experimental data from a full-scale pile load test. Interesting conclusions have also been drawn regarding the discretization of the computational domain and the combination of 3D numerical nonlinear analysis and the structural beam theory.
