Special Issue Information

Dear Colleagues,

For many years, structural health monitoring (SHM) has been a very important aspect of scientific works and different engineering applications, including in the construction industry.

Although SHM issues and the related nondestructive testing (NDT) methods were initially mainly concerned with aerospace applications and metal or composite materials, concrete structures have also recently been monitored. For this, both established methods as well as new developed techniques are used.

There are effective methods for detecting surface damage to concrete elements, whatever their origin. These methods are able to successfully detect and monitor the development and propagation of cracks resulting from material degradation as well as the exceeding of acceptable loads. NDT techniques are also available to detect damage resulting from the chemical degradation of concrete and corrosion of reinforcements. Effective approaches are being developed to monitor structures that, having been in operation for a long time, require special attention, as well as new structures often characterized by complex geometries with ambitious and original architectural projects. A separate group of applications for NDT-SHM methods are represented by reinforced concrete structures with composite bars, which are gaining increased popularity.

The aim of this Special Issue is to bring together researchers studying and developing NDT-SHM methods focused on applications in reinforced concrete, both at the material and at the structure scale. It is expected that this Special Issue will provide new information on the application of NDT to a wide variety of structures (bridges, reinforced concrete frame structures, dams, reinforced concrete tanks, etc.) in the fields of Civil Engineering and Architecture. Original research papers, experimental and numerical studies and reviews be showcased in this Special Issue. We look forward to receiving your contributions.

In order to achieve a comprehensive and accurate evaluation of the safety of compression members made of circular steel tubes, image processing technology is commonly utilized to extract the morphology of the steel tubes before and after rust removal. The obtained results have validated the feasibility and applicability of employing digital cameras and image processing technology to analyze the images of the steel tubes before and after rust removal and to extract useful structural mechanics features. The feature values of the apparent morphology before rust removal grow with the increase of the corrosion depth, while after rust removal, the feature values first increase and then decrease with the growth of the corrosion depth. Based on this fact, a simplified equation is proposed to quantify the relationship between the feature values of the apparent morphology before and after rust removal and the corrosion depth. In continuing, a simple, fairly accurate, and comprehensive safety evaluation methodology for corroded circular steel tubes under compression is established. Finally, an example is illustrated to check the applicability and effectiveness of the proposed approach. Full article
