Evaluation of uplift interpretation criteria for drilled shaft capacity / Yit-Jin Chen in Journal of geotechnical and geoenvironmental engineering, Vol. 134 N°10 (Octobre 2008) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 134 N°10 (Octobre 2008) . - pp. 1459–1468 Titre : Evaluation of uplift interpretation criteria for drilled shaft capacity Type de document : texte imprimé Auteurs : Yit-Jin Chen, Auteur ; Hsin-Wen Chang, Auteur ; Fred H. Kulhawy, Auteur Année de publication : 2008 Article en page(s) : pp. 1459–1468 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Drilled  shafts  Foundations  Uplift  Load  tests  Displacement Résumé : Representative interpretation criteria are examined to evaluate the capacity of drilled shaft foundations under axial uplift loading. A wide variety of uplift load test data are used, and these data are divided into drained and undrained databases. The interpretation criteria are applied to these load test data to establish a consistent uplift interpretation criterion. The results are comparable for both drained and undrained loading. In general, the undrained load test results show somewhat less variability than the drained results. Based on these analyses, the QL2 , Q0.5in , and slope tangent methods are the more reliable and consistent, and specific design recommendations for the interpretation of uplift drilled shaft load test are given, in terms of both capacity and displacement.
