Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 16 N° 1 (Janvier 2012) . - pp. 20-42 Titre : Structural monitoring : Identification and location of an impact on a structurally dissipating rock-shed structure using the inverse method Type de document : texte imprimé Auteurs : Z. Boukria, Auteur ; P. Perrotin, Auteur ; A. Bennani, Auteur Année de publication : 2012 Article en page(s) : pp. 20-42 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Inverse  problem  Identification  Location  Transfer  function  Reinforced  concrete  slab  Tikhonov  regularisation  Numerical  model Résumé : In this study we developed an experimental method to identify the impact force on a reinforced concrete slab. A transfer function obtained experimentally between the acceleration response and the force history applied to a point of the structure was used. To regularise the solution obtained with this inverse problem, we used the Tikhonov method. To locate the impact force, we used an experimental method based on the minimisation of an objective function created from the transfer functions between several impact locations, forming a mesh structure, and several measuring points. Characterising the impact means locating the impactor and identifying the load. Meanwhile, a numerical model is developed using Abaqus to characterise impact force, and allow access to the state constraints and damage level.
