“…However, corrosion is a main factor shortening the fatigue life of cables dramatically. Li et al [45,46,51,53,57] investigated the effect of corrosion on the fatigue life of steel wires and cables. The tested wires and cables were replaced on an actual cable-stayed bridge.…”

“…AE method for cable damage monitoring has been extensively investigated and implemented into practical cable-stayed bridges. Li et al [45,46] and Li and Huang [49] proposed an AE-based method to monitor the evolution of fatigue damage of steel stay-cables and carbon-fiber reinforced-polymer cables. The cable fatigue failure was well characterized by AE characteristic parameters such as the b value, Kurtosis index, and fractal dimension.…”

“…The results indicated that the fatigue damage started from the pit corrosion of steel wires, which remarkably shortened the fatigue life of the cable. Faber et al [24] proposed an approach to calculate the reliability of stay cables with monitoring or inspection data, and Li et al [45,46,51,53] further investigated the influence of corrosion on the fatigue life of steel wires and cables by using the model proposed by Faber et al [24]. Kodakalla et al [40] also reported that fatigue life of replaced strands have been experimentally investigated in German and the results indicated that the fatigue life of the replaced strands is considerably different (random) and the poor fatigue life is from the samples low ends of cables near the deck, which is consistent with those results obtained by Li et al [45,46,51,53].…”

Cable-stayed bridges are a type of long-span bridges that have been extensively constructed throughout the world. However, cable-stayed bridges suffer from a variety of performance deteriorations and natural disasters during their service time. Structural health monitoring, having emerged since the early 1990s, is regarded as an in situ field experimental technique to understand the behaviors and performance of real, full-scale bridges under real loadings and environmental conditions and to further ensure the safety, serviceability, durability, and sustainability of bridges. In this paper, the existing various monitoring technologies for cable-stayed bridges developed are overviewed. The design approaches of structural health monitoring systems for cable-stayed bridges are introduced. The data analysis, modeling, and safety evaluation of cable-stayed bridges based on structural health monitoring technology are addressed. The applications of structural health monitoring technology for cablestayed bridges are summarized. The design code for structural health monitoring systems is described for large highway bridges (including cable-stayed bridges) that are authorized by the Ministry of Transportation in China. Finally, this study discusses the challenges and future trends in structural health monitoring technologies for cable-stayed bridges, particularly for data-driven science and technology in structural health monitoring field.

“…When cable supported bridges are under loads, the steel components such as orthotropic steel decks and stay cables will emit energy in the form of elastic waves due to various material-relevant damage mechanisms [25]. These waves can be detected by attached AE sensors [26][27][28] and further evaluation of the collected data can be used to assist decisions for bridge maintenance and rehabilitation.…”

ABSTRACT:Initial cost was mainly considered in constructing a bridge in the past, whereas future payments such as the cost of strengthening or rehabilitation were neglected. This situation has brought numerous economic as well as social problems due to the lack of rational maintenance and rehabilitation strategies. Thus, it is necessary and urgent to develop appropriate bridge maintenance and rehabilitation strategies that not only meet serviceability criteria but also consider the life-cycle cost (LCC) optimization. This paper discusses major hazards of in-service cable supported bridges, including fatigue cracking of orthotropic steel decks, deterioration of cables, damage of main cables, hangers and expansion joints et al. Advanced maintenance and rehabilitation tools are introduced to save the life-cycle cost, acoustic emission monitoring technique and cold retrofit technique are detailed studied. A framework is provided for the strategies of maintenance and rehabilitation based on life-cycle cost. The framework takes into account of the safety, serviceability and sustainability during the lifetime of cable supported bridges.

Summary The monitoring and localization of defects and wire breaking of bridge cable are vital to the safe operation of the whole bridge. In this work, an innovative monitoring method that uses waveguides to draw out the steel wires at the end of the cable is proposed. This monitoring method can effectively capture the acoustic emission (AE) signal produced by defects and wire breaking of the cable. The transverse position of the wire breaking can also be accurately located so as to provide basis for the decision making of maintenance department. The pencil‐lead breaks (PLB) test method is utilized to investigate the influence of the transition modes between the waveguide and the sensor and the connection modes between the waveguide and the cone on the AE signal. The PLB test and tensile test method are utilized to examine the AE signal characteristics of different sensors at the end of steel wires. Results showed that the cone transition between the waveguide and the sensor and the welding connection between waveguide and cone exhibit the minimum effect on AE waveform and parameters, such as amplitude, compared with that of the reference sensor without waveguide. In the tensile test, the transverse position of the wire breaking cannot be identified by analyzing the AE signals collected by each senor when the wire breaks, whereas it can be identified in the process of defects before the wire breaks.
