“…The impacts of using this method on the environmental impact of the considered structure have been discussed. So, the PSD equation can be obtained according to the transfer function as the following equations [39,41,48,49]: As the diagram in Figure 2 shows, this research investigated the performance aspect of the LCA that was used. In addition, it evaluated the PSD method's performance as a signal-based method with a different approach to diagnosing the damage caused by chloride ions to repair and maintain a bridge.…”

“…Among the various signal-based methods are those that operate in either the time domain technique [24,25], the frequency domain technique [26,27], or the time-frequency domain technique [28,29]. Some dynamic frequency-domain approaches used as non-destructive damage detection methods include natural frequencies [30,31], modal curvatures [32,33], modal strain energies [34,35], frequency response functions (FRF) [36,37], and power spectral density (PSD) [38,39]. Of these methods, the PSD is one of the frequency-domain techniques that use the responses of a periodic or randomized stimulus in frequencies to describe the mean power repartition.…”

Recently, using economic damage identification techniques to ensure the safety of bridges has become essential. But investigating the performance of those techniques for various conditions and environments and, in addition, a life cycle assessment (LCA) through these methods depending on the situation and during the life of a structure could help specialists and engineers in this field. In these regards, analyzing the implementation of a technique for the restoration and maintenance stages of costly structures such as bridges can illustrate the effect of each damage detection method on the LCA. This research assessed non-destructive abilities and a dynamic approach to predict the amount and location of damages in the LCA. For this purpose, the power spectral density (PSD) technique’s performance by different approaches in identifying corrosion damages for a coastal bridge and the effectiveness of using this technique on reducing the environmental impact compared with a conventional method were evaluated. The results demonstrate a reduction of the environmental impacts by approximately 23% when using the PSD during the bridge’s service life. In conclusion, the PSD approach does well in anticipating the damage quantity and location on a coastal bridge, which reduces the environmental impacts during the repair and maintenance.

Recently, the repair and maintenance of structures has been necessary to prevent these structures’ sudden collapse and to prevent human and financial damage. A natural factor in marine environments that destroys structures and reduces their life is the presence of chloride ions. So regular health monitoring of concrete coastal buildings for on-time repair is essential. This study investigates the performance of the power spectral density (PSD) method as a non-destructive damage-detection method to monitor the location and amount of damage caused by chloride ions during a structure’s life using different approaches according to life-cycle assessment (LCA) and life-cycle cost assessment (LCCA). In this regard, chloride corrosion damage dependent on zone distance from seawater was first calculated to obtain the service life of each part of a coastal concrete bridge according to the conventional method. Based on rebar corrosion each year, the next stage forecasted the bridge’s concrete deterioration. The PSD method monitored the annual loss of reinforcement cross-sectional area, changes in dynamic characteristics such as stiffness and mass, and the bridge structure’s life using sensitivity equations and the linear-least-squares algorithm. Finally, according to the location and quality of damage in each year of bridge life until the end of life, LCC and maintenance and repair costs of the PSD method were compared with the conventional method. The results showed that this strategy was very effective at lowering and optimizing the costs of maintenance and repair caused by chloride corrosion.

“…Several signal-based approaches as non-destructive methods include the time, frequency, and time-frequency domains (Liu et al, 2023). Some usable frequency domain techniques as variations in dynamic features, including natural frequency (Khodadadi & Mirjalili, 2022;Loya, Aranda-Ruiz & Zaera, 2022), modal Curvatures (Yang et al, 2022;Nguyen et al, 2020), mode shape (Hassani, Mousavi, & Gandomi 2022;Zhang et al, 2022), modal strain energy (MSE) (Shirazi et al, 2023;Daneshvar, 2022;Nguyen, & Livaoğlu 2022), frequency response functions (FRF), and power spectral density (PSD) (Fang et al 2023;Hadizadeh-Bazaz, Navarro, & Yepes 2022) are employed in vibration-based damage detection, some popular non-destructive testing methods.…”

Experts and governments have long focused on reducing the costs of repairing and maintaining crucial structures such as bridges through continuous maintenance and repair. In the meantime, using appropriate methods for identifying possible damage and researching how much a partial re-design will lower the costs of repairing and maintaining a structure over its lifetime, considering the structure's environment and damage causes. This study explores the costeffectiveness of two damage prediction methods using the power spectral density (PSD) method compared to the conventional method of detecting damage by re-designing different concrete cover thicknesses for a coastal reinforced concrete bridge. The study evaluates the impact of chloride ions on the location and extent of damage over the bridge's lifetime and compares the total maintenance and repair costs. The results show that while the PSD method is effective for concrete structures with low concrete covers, increasing the concrete cover thickness may result in higher repair costs.Keywords: life cycle cost assessment; non-destructive damage detection methods; coastal concrete bridge; steel corrosion; chloride corrosion; maintenance and repair techniques Palabras clave: evaluación del coste del ciclo de vida; métodos no destructivos de detección de daños; puente costero de hormigón; corrosión del acero; corrosión por cloruros; técnicas de mantenimiento y reparación Agradecimientos: This research was funded by MCIN/
