Recent Advancements in Non-Destructive Testing Techniques for Structural Health Monitoring

Structural health monitoring (SHM) is an important aspect of the assessment various structures and infrastructure, which involves inspection, monitoring, maintenance to support economics, quality life sustainability in civil engineering. Currently, research has been conducted order develop non-destructive techniques for SHM extend lifespan monitored structures. This paper will review summarize recent advancements testing techniques, namely, sweep frequency approach, ground penetrating radar, infrared technique, fiber optics sensors, camera-based methods, laser scanner acoustic emission ultrasonic techniques. Although some are widely successfully utilized engineering, there still challenges that researchers addressing. One common within interpretation, analysis automation obtained data, requires highly skilled specialized experts. Therefore, investigating applying artificial intelligence, namely machine learning algorithms address challenges. In addition, have combined multiple improve accuracy acquire additional parameters enhance measurement processes. study mainly focuses on scope Non-destructive Testing (NDT) application concrete, masonry, timber steel
