This paper presents the results of the application of several Non-Destructive Techniques (NDT): Ground Penetrating Radar (GPR) and Wireless Sensor Networks (WSN) on a Case Study Bridge. This provides crucial structural information such as rebar position, moisture ingress and deflection. The results of all of the above are compared in order to identify the portion of the bridge which had undergone the greatest amount of deterioration. This process forms the basis for the integrated bridge health mechanism proposed by this paper. This mechanism can be used to provide the detailed structural evaluatio for reinforced concrete bridges by future engineers

Bu yayında belirlenen örnek çalışma köprüsü üzerinde gelişmiş Tahribatsız Muayene Teknikleri (TMT): Yeraltı Radarı (YR) ve Kablosuz Sensör Ağı (KSA) kullanılarak elde edilen sonuçlar detaylı biçimde ele alınmıştır. Köprülerin yapısal bilgileri olarak donatının yeri, nem bilgisi ve herhangi bir noktasındaki sapmaları belirlenir. Özet olarak, yukarıda bahsedilen tekniklerin kullanımı ile köprülerin yapısal bütünlük ve genel fonksiyonelliklerinin değerlendirilmesi ve gözetimi için bir tümleşik model/yaklaşım geliştirilmek istenmiştir. Bu çalışma, potansiyel olarak köprü yapılarının mekanik ve fiziksel davranışlarının daha iyi bir şekilde anlaşılmasına yönelik katkı sağlayabilir ve sonuç olarak öngörülen yaşam sürelerini ve işlevselliklerini değerlendirebilir. Bu mekanizmanın gelecekte mühendisler tarafından betonarme köprüler üzerinde detaylı yapısal değerlendirmeler sunmak için kullanılabileceği düşünülmektedir
