“…From the above bases, the SHM system for the bridge must be designed based on the design characteristics and technical features of the bridge and clearly defining the number of objects, the main reasons need to measure and observe. Furthermore, the selection of the system's monitoring equipment should consider the following factors [4]: -Design features, the structure of the bridge, surrounding natural environment -Components to be observed, quantities to be observed -Economic efficiency -Precision and durability of sensors.…”

Tran Hoang Na arch bridge connects the Tran Hoang Na Street and Can Tho Bridge's approach road. The arch bridge is a kind of arch structure with super-static, high deformation. For large steel, the arched bridge is essential to control stress, deformation, and temperature values in the bridge's main structure. It allows managing quality during bridge construction and operation stage. This kind of structure is also affected by environmental factors, especially temperature influence, temperature difference during the day and in the annual cycle, and the impact of wind on hanging cables. The main girder, arches, and arch support construction can be deformed due to the effect of creeping (CR), shrinkage (SH), temperature changes (TU), and temperature gradients (TG). This paper presented the proposed complete SHM system for this arch bridge integrated with acoustic emission (AE) technology to control destructive activities in the bridge and monitor cracks in steel and concrete structures.

Featured Application: The data collected can be the basis for determining the structural condition of the structure.Abstract: Durability, safety, and usability are the three foundations of structural reliability, vital in the economic and social context. As the locating and tracking of potential damage and evaluating its impact on the condition of the structure are part of service life assessment, relevant methods should be developed that would detect the onset of the deterioration process and enable the monitoring of its progress within the entire volume of the structure, not only in the areas selected in a subjective way. The acoustic emission (AE) method relying on the analysis of active destructive processes can be the best choice. This article reports the results of the application of the AE method for identifying active destructive processes and tracking their development during the routine operation of various types of structures.

“…Metal, plastik ve beton gibi materyaller bu test yöntemi kullanılarak muayene edilebilir [1,12]. Pasif (statik) kusurlar ve aktif kusurlar, materyal sağlığını tehdit eden kusur çeşitleridir ve AE yöntemi bu tür kusurları tespit etmede başarılıdır [27]. Şekil 7'de AE testi sistem şeması gösterilmiştir.…”

Bu çalışmada, materyallerin kusur analizini gerçekleştirerek güvenli materyal kullanımı sağlayan tahribatsız test yöntemleri incelenmektedir. Tahribatsız test işleminde kullanılacak yöntemin, çalışma şartları açısından test edilecek materyal üzerinde uygulanabilir olması gerekmektedir. Örneğin girdap akımları yöntemi, çalışma şartları gereği ferromanyetik metalleri test edemezken, ferro olmayan metalleri test edebilmektedir. Bu şartlar göz önüne alınarak seçilen test yöntemi ile materyal düzenli aralıklarla tahribatsız muayene edilerek kusurlu materyal bölgeleri tespit edilmektedir. Bu şekilde güvenli materyal kullanımı sağlanarak büyük maddi kayıplar önlenmiş olur. Tahribatsız test yöntemlerinin bir kısmı güvenilir sonuçlar üretmesi açısından endüstride yaygın olarak kullanılmaktadır. Bu bağlamda manyetik kaçak akı, akustik emisyon, ultrasonik, girdap akımları ve radyografi yöntemleri bu çalışmada incelenmiştir. Yöntemlerin işleyiş prensipleri, literatürde yapılmış çalışmalar ve gerçekleştirilmiş deneyler incelenerek açıklanmıştır. Yöntemler karşılaştırmalı olarak seçilen kriterlere göre sınıflandırılmıştır. Bu çalışma ile geniş içeriğe sahip bir derleme ortaya çıkarılmıştır.
