Abstract:
Structural health monitoring (SHM) and nondestructive testing (NDT) are frequently employed to assess or track the condition of concrete structures. While SHM and NDT are frequently discussed in the same context, and the terms have even been used interchangeably, they refer to different techniques and have their own distinct objectives. However, confusion persists within the industry about what constitutes NDT and what constitutes SHM; in some instances, certain techniques are categorized as both SHM and NDT. Additionally, terms like nondestructive evaluation (NDE), nondestructive inspection (NDI), and structural monitoring, among others, are also used. ACI Committees 228 (Nondestructive Testing of Concrete) and 444 (Structural Health Monitoring) are working to formalize the distinction between SHM and NDT and define terms used in these fields. Ultimately, this will lead to a better understanding and increased adoption of SHM and NDT within the concrete industry. The primary goal of this forum is to alleviate confusion within the industry about the distinction between SHM and NDT. The forum will define SHM and NDT, explain the relationship between them, and give examples of how they are applied within the concrete industry. The forum will introduce the development of SHM and NDT, discuss the current state of the art, their inter-relations, and provide a vision for future directions in both areas.
