Radar-based measurement of deflections on bridges and large structures / Carmelo Gentile in European journal of environmental and civil engineering, Vol. 14 N° 4 (Avril 2010) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 14 N° 4 (Avril 2010) . - pp. 495-516 Titre : Radar-based measurement of deflections on bridges and large structures Type de document : texte imprimé Auteurs : Carmelo Gentile, Auteur ; Giulia Bernardini, Auteur Année de publication : 2011 Article en page(s) : pp. 495-516 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Bridge  Microwave  interferometry  Remote  sensing  Radar Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Recent progresses in radar techniques and systems have favoured the development of microwave interferometers, suitable to the non-contact measurement of deflections on large structures. The main characteristic of the new radar systems is the possibility of simultaneously measuring the static or dynamic deflection of several points on a large structure with high accuracy. The objectives of the paper are: a) to discuss some radar techniques implemented in the microwave interferometer, in order to highlight advantages and potential issues of the radar-based measurement; b) to illustrate the application of the radar technique in live-load static and ambient vibration tests performed on a full-scale bridge.
