Performance assessment model of non-destructive technologies in inspecting concrete bridge decks

Abstract

Non-destructive testing (NDT) methods are typically utilized to thoroughly inspect existing defects in the concrete bridge deck and tackle the limitations of common inspection practices (e.g., visual inspection). Nevertheless, the reliability of inspection outcomes crucially depends on choosing the most appropriate NDT technologies. In this regard, a comprehensive Performance Assessment Model (PAM) was developed. The developed model incorporated 40 parameters to precisely assess the performance of different NDT technologies from diverse perspectives (e.g., defect detection capability, ease of use, speed, and cost). The required data were collected through a survey questionnaire. The model utilized the Analytic Network Process (ANP) technique to calculate the importance weight of each parameter, whereas the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) was exploited to compute the performance index (PI) of NDT technologies. The outcomes of this study clearly illustrate the disparity in the performance of different NDT technologies. Furthermore, it was shown that none of these technologies could either exhibit the best performance in all the proposed parameters or efficiently identify all types of defects. Based on the PAM results, a selection model was proposed to assist bridge authorities and consultants in choosing the most efficient NDT technologies for inspection purposes.

Condition Monitoring of Reinforced Concrete Bridge Decks: Current Practices and Future Perspectives

“…NDE methods can be categorized into five main groups as shown in Figure 2: digital imaging, electro-magnetic (e.g., ground-penetrating radar), thermal (e.g., infrared thermography), electro-chemical (e.g., halfcell potential and electrical resistivity), and acoustic (e.g., chain dragging & hammer sounding, ultrasonic surface wave, ultrasonic pulse echo and impact echo). For more information about defects and NDE methods for highway bridge decks, the reader may refer to Abdelkhalek and Zayed [9], Yehia, et al [10], Omar and Nehdi [11], Abdelkhalek and Zayed [12], Gucunski, et al [13]. A brief description of these methods is presented through the following subsections.…”

Key Factors for a Successful OBM Transformation with DEMATEL–ANP

“…ANP is a nonlinear structure that has been proposed to analyze criteria priorities and their complex relationships [30]. ANP exhibits the advantage of analyzing complex and interdependent decision-making situations, such as resource allocation, technology selection, or strategic planning [31]. Other MCDM methods and variants, such as the technique for order of preference by similarity to ideal solution (TOPSIS), VIKOR, gray theory, AHP, ANP, and DEMATEL or fuzzy MCDM, have also been developed to solve different problems, with each method having its own characteristics for finding the best solutions [32][33][34].…”

Application of Impact Elastic Wave Method in Quality Inspection of Concrete Lining

“…Nondestructive testing (NDT) technology is used for quality testing on the premise of not damaging the inherent structure of concrete. Due to its advantages of non-damage, fast and simple, the detection results are universal, and it is widely used in concrete quality testing at present [3,4]. The GPR method has a good effect in grouting defect detection after shield tunnel segment [5], but the interpretation of radar image results is more dependent on professional technicians.…”
