Prediction of frame structure damage resulting from deep excavation / Darwid Halim in Journal of geotechnical and geoenvironmental engineering, Vol. 138 N° 12 (Décembre 2012) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 138 N° 12 (Décembre 2012) . - pp. 1530–1536 Titre : Prediction of frame structure damage resulting from deep excavation Type de document : texte imprimé Auteurs : Darwid Halim, Auteur ; Kai Sin Wong, Auteur Année de publication : 2013 Article en page(s) : pp. 1530–1536 Note générale : Géotechnique Langues : Anglais (eng) Mots-clés : Excavation  Building  damage  Settlement  Frame  structure Résumé : Ground movements caused by deep excavations may potentially lead to building damages in urban cities where the majority of buildings are frame structures. A new damage chart, with two key parameters of the differential settlement and frame dimensions, has been proposed. The chart has been validated against published data, and field measurements have been obtained during the construction of mass rapid transit (North East Line) in Singapore. The proposed chart can be used as an alternative or a supplement to other similar charts. Although the measurement of the frame dimensions is straight forward, the accuracy of the chart highly depends on the predicted building settlement, which still remains a challenge.
