Fully probabilistic framework for evaluating excavation-induced damage potential of adjacent buildings / C. Hsein Juang in Journal of geotechnical and geoenvironmental engineering, Vol. 137 N° 2 (Fevrier 2011)

Fondations. Tunnels Résumé : This paper presents a framework for a fully probabilistic analysis of the potential for damage to buildings adjacent to an excavation. Herein, the damage potential index (DPI), which is a function of angular distortion and lateral strain, is used to assess building damage potential. A serviceability limit state is established in which the resistance is expressed in terms of the “limiting” DPI, and the load is represented by the “applied” DPI. In this context, damage to the building adjacent to an excavation is said to occur deterministically if the applied DPI is greater than the limiting DPI. For the fully probabilistic analysis, both parameter and model uncertainties of the limiting and applied DPIs are first characterized. The analysis framework is then presented and demonstrated with a case history. Finally, sensitivity analysis is performed to identify the factors to which the probability of damage is most sensitive and to analyze the effect of various assumptions of the input parameters on the computed probability of building damage.

Reliability analysis and updating of excavation-induced ground settlement for building serviceability assessment / Evan C. Hsiao 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. 1448–1458 Titre : Reliability analysis and updating of excavation-induced ground settlement for building serviceability assessment Type de document : texte imprimé Auteurs : Evan C. Hsiao, Auteur ; Matt Schuster, Auteur ; C. Hsein Juang, Auteur Année de publication : 2008 Article en page(s) : pp. 1448–1458 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : Reliability  Probability  Bayesian  analysis  Excavation  Settlement  Serviceability  Damage Résumé : In this paper, the excavation-induced settlement determined by the KJHH model, a recently developed semiempirical model, is used to assess the serviceability reliability of adjacent buildings. The calculated settlement, considered as the load in the context of reliability analyses in this paper, is compared with a tolerable settlement, considered as the resistance herein. The reliability of the adjacent building against “damage” (defined herein as the violation of serviceability requirements such as having intolerable settlement) is first analyzed and the probability of exceedance (i.e., exceeding the tolerable settlement) is calculated. Furthermore, as the excavation proceeds, observed settlement at the current excavation stage is used to update the prediction of settlement at subsequent stages, and the probability of exceedance is updated accordingly.

Simplified model for evaluating damage potential of buildings adjacent to a braced excavation / Matt Schuster in Journal of geotechnical and geoenvironmental engineering, Vol. 135 N° 12 (Décembre 2009) 

Public ISBD [article]  in Journal of geotechnical and geoenvironmental engineering > Vol. 135 N° 12 (Décembre 2009) . - pp. 1823–1835 Titre : Simplified model for evaluating damage potential of buildings adjacent to a braced excavation Type de document : texte imprimé Auteurs : Matt Schuster, Auteur ; Gordon Tung-Chin Kung, Auteur ; C. Hsein Juang, Auteur Année de publication : 2010 Article en page(s) : pp. 1823–1835 Note générale : Geotechnical and geoenvironmental engineering Langues : Anglais (eng) Mots-clés : ExcavationBracingBuildingsDamageDeflectionSettlementStrainUncertainty  principlesProbability Résumé : This paper presents a simplified model for evaluating damage potential of a building adjacent to a braced excavation. New developments include several component models for estimating the lateral ground movement profile, angular distortion and lateral strain in a building, and damage potential of a building adjacent to an excavation. These new developments along with an existing model for the vertical ground movement profile are integrated into the proposed simplified model. Case histories are used to verify the developed simplified model. Furthermore, the uncertainty in the developed model is quantified, which enables a probabilistic assessment of the excavation-induced building damage potential. An example probabilistic assessment of building damage potential is presented.
