The Current Development of Structural Health Monitoring for Bridges: A Review

Abstract

The health monitoring system of a bridge is an important guarantee for the safe operation of the bridge and has always been a research hotspot in the field of civil engineering. This paper reviews the latest progressions in bridge health monitoring over the past five years. This paper is organized according to the various links of the bridge health monitoring system. Firstly, the literature on monitoring technology is divided into two categories, sensor technology and computer vision technology, for review. Secondly, based on the obtained monitoring data, the data processing methods including preprocessing, noise reduction, and reconstruction are summarized. Then, the technical literature on abnormal data early warning systems is summarized. The recent advances in vibration-based and non-destructive testing-based damage identification methods are reviewed in the next section. Finally, the advantages and disadvantages of the existing research and the future research directions are summarized. This review aims to provide a clear framework and some reliable methods for future research.

Online Real-Time Monitoring System of A Structural Steel Railway Bridge Using Wireless Smart Sensors

“…The Internet of Things (IoT) and artificial intelligence (AI) are related to this technology. Furthermore, the expert system can be adopted for civil engineering purposes [13], [41], [54], [55]. The development of expert systems covers user interfaces, knowledge bases, engine interfaces, and development engines [12], [48], [52], [54].…”

Structural Health Monitoring for Prefabricated Building Envelope under Stress Tests

“…In recent years, both civil construction and the building sector have explored the utilization of sensing technologies for SHM embedded in their structure [6,7]; in particular, focus has been given to the SHM of bridges [8,9]. However, the integration of sensors into non-load-bearing structures, such as a curtain wall façade, represents an increasing topic that needs to be further investigated.…”

“…In fact, modal parameters can be used to evaluate the safety condition of a structure and assess structural health based on modal parameters [25]. Deng et al [9] demonstrated that temperature is an important factor that affects the natural frequency of the bridge, and it is not negligible. Therefore, the temperature must be controlled in order to not consider a variation in frequency only due to temperature change as a damage indicator.…”

The Sustainable Development of Bridges in China: Collapse Cause Analysis, Existing Management Dilemmas and Potential Solutions

“…Nonetheless, it remains crucial to continue conducting research and employing innovative approaches to minimize the occurrence of such accidents and their detrimental consequences. In an effort to enhance the safety and reliability of bridges and minimize the incidence of bridge collapse accidents, numerous scholars and experts have conducted comprehensive statistical investigations into the causes of bridge collapses [13][14][15]. The study of bridge collapse encompasses several disciplines, such as structural engineering, monitoring technology [16,17], transportation, and earthquake engineering, among others, and research methods employed in this area include theoretical analysis, experimental testing, numerical simulation, and case studies.…”
