Dealing with Uncertainties When Using Non Destructive Techniques for Assessing Construction Material Properties: Identification of Major Sources and Their Consequences

“…It is why non-destructive testing (NDT) techniques offer an interesting alternative. During these last years, a number of collaborative research programs have been developed in order to improve NDT strategies on concrete, and variability assessment had been one of their focuses (Balayssac et al, 2012. The necessity has been demonstrated of making the part between three different degrees of variability, which correspond to different phenomena : -at point scale (Scale-1), the variability is due to a non perfect reproducibility when the measurement is repeated and when exactly the same results would have to be expected.…”

Corroboration of NDT and deconvolution neural networks for pedestrian bridge health assessment

“…With their steady technological development, NDT methods are becoming increasingly affordable, and thus more attractive to engineers within the field. [4,9,10] By using two or more methods of inspection, engineers can be assured that they possess a complete picture of a structure's condition and this is considered by some specialists to be the way forward for concrete assessment. For example, GPR and ultrasound thermography techniques can each provide structural data that may be missing from the other, thereby reducing the impact of the known vulnerabilities of each technique (GPR is known to be vulnerable to water and porosity whilst ultrasound is vulnerable in conditions of density and moisture).…”

Köprü Yapilarinda Yeralti Radari (Yr) Ve Kablosuz Sensör Aği (Ksa) İle Oluşturulan Sağlik Değerlendi̇rme Si̇stemi̇

“…Köprüler, toplumun altyapı varlığının ve mirasının önemli bir parçasını teşkil eder ve inşaat malzemelerinin doğal bir bozulma sürecine tabidirler ki bu da büyük mali sonuçlara ve en kötü durumunda ölümle sonuçlanan felaketlere yol açabilmektedir. Sonik/ultrasonik, elektromanyetik, elektrikli ve kızılötesi termografi [1], [2] gibi Tahribatsız Muayene Teknikleri (TMT) değerlendirme yöntemlerinin her biri, teste tabi tutulan yapının [3] fiziksel durumuna ilişkin bilgi verebilir fakat bu zamana kadar çalışmalar ağırlıklı olarak laboratuvarda gerçekleşmiştir [4], [5], [6]. TMT zaman ve para açısından yüksek maliyetlidir fakat devam eden teknolojik gelişimiyle bu maliyetler azalmakta ve bu da Yeraltı Radarı (YR) ve Kablosuz Sensör Ağı (KSA) gibi teknolojilere olan ilgiyi artırmaktadır.…”
