A Review on the Latest Advancements and Innovation Trends in Vibration-Based Structural Health Monitoring (SHM) Techniques for Improved Maintenance of Steel Slit Damper (SSD)
Abstract
Steel slit damper (SSD) is specifically engineered to absorb and disperse energy to mitigate the possibility of structural damage and collapse during seismic events. However, the effectiveness of these dampers are compromised due to wear, corrosion and other forms of material degradation and failure mechanisms. For this reason, it is important to consistently monitor its condition and conduct maintenance and repairs to guarantee safety and dependability of the structures it is installed with. Now, vibration-based techniques have emerged as a promising structural health monitoring (SHM) strategy. It involves methodologies for detecting changes in functions and analyzing vibrations to discover potential problems. This study entails a comprehensive examination of the most recent advancements and breakthroughs in vibration-based methodologies used in SHM. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020), we identified several key techniques and technologies that show promise in enhancing the maintenance and monitoring of steel– or steel and metal surfaces- slit dampers. The pros and cons of these methods are presented to be applicable when monitoring an SSD. This paper presents notable figures and their corresponding discussions to achieve enhanced understanding of the advancements in SHM towards sensor technologies, monitoring techniques, and applications in civil infrastructure. Furthermore, this paper reviews the applications and functions framework for real-time SHM of SSDs together with their practical implementations and applications using diverse monitoring technologies to promote innovation. Finally, the optimal sensor selection criteria, data gathering methodologies, experimental settings, innovative approaches with comparative analyses, and a proposed maintenance standard for SSDs are described in this study.
