Coupled macroelement model of soil-structure interaction in deep foundations / Changsoon Rha in Journal of engineering mechanics, Vol. 133 N°12 (Decembre 2007) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 133 N°12 (Decembre 2007) . - pp.1326–1340. Titre : Coupled macroelement model of soil-structure interaction in deep foundations Type de document : texte imprimé Auteurs : Changsoon Rha, Auteur ; Ertugrul Taciroglu, Auteur Année de publication : 2007 Article en page(s) : pp.1326–1340. Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Soil-structure  interaction  Pile  lateral  loads  Vertical  loads  Drilled  shafts  Piers  Deep  foundations Résumé : The principal objective of this study is the development and calibration of a macroelement model for soil-pile interaction under simultaneously applied lateral and vertical loads. Herein, we focus on cast-in-drilled-hole single piles that are partially or fully embedded in soil, which are frequently used as support structures in highway construction. The model is calibrated and verified using primarily three-dimensional finite-element simulations and, whenever possible, with experimental data obtained from open literature. These data indicate that lateral loads significantly affect the vertical response of single piles, whereas the converse coupling is negligible. The proposed macroelement model is capable of mimicking this phenomenon. As such, it is a computationally efficient alternative to finite-element analyses, and is feasible to be utilized in practical applications.
