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.

“…It is important to be able to monitor the structural integrity of these structures. Dynamic testing, visual as well as sensors had been employed for this purpose by several researchers like B [1], C et al [2], D et al [3], F et al [4], I [5], I et al [6], I et al [7], I et al [8], I and O [9], R et al [10], R et al [11], R [12].

A method of detecting honeycombing damage in a reinforced concrete beam using the finite element model updating technique was proposed. A control beam and two finite element models representing different severity of damage were constructed using available software and the defect parameters were updated. Analyses were performed on the finite element models to approximate the modal parameters. A datum and a control finite element model to match the datum test beams with honeycombs were prepared. Results from the finite element model were corrected by updating the Young's modulus and the damage parameters. There was a loss of stiffness of 3% for one case, and a loss of 7% for another. The more severe the damage, the higher the loss of stiffness. There was no significant loss of stiffness by doubling the volume of the honeycombs.
