Early Warning of Abnormal Train-Induced Vibrations for a Steel-Truss Arch Railway Bridge: Case Study

Abstract: Considering the new challenges for high-speed railway bridges, the early warning of abnormal train-induced vibrations is necessary for ensuring the operation safety of both the bridge structures and the trains on the bridge. In this study, an online monitoring system for detecting abnormal train-induced vibration responses is developed, and the Dashengguan Yangtze River Bridge is used for illustration. First, to accurately investigate the influence of different train lanes and the number of carriages on train-… Show more

“…As vehicle tonnage and truck traffic are increasing, full-load operation of various bridges has become more common [2]. According to Ding et al [3], various natural disasters and man-made influences have also led to many bridges that have not been maintained in time, leading to increased risks. Ensuring the safe operation of bridge structures has become an important issue of concern to the government and the public worldwide.…”

“…The temperature-induced strain is in the low-frequency band and the vehicle-induced strain is in the high-frequency band. 15,16 The decomposition scale of the wavelet transform can be determined by the frequency spectrum of the signal. 17 Assume that the signal frequency of structural temperature data is mainly concentrated at [0, f t ].…”

“…Seo et al, 10,11 Bao et al, 12 Li et al, 13 and Yu and Cai 14 analyzed the load effects of bridge components using advanced signal and data processing method. Ding et al 15 and Zhao et al 16,17 conducted the real-time early warning of long-span bridges to monitor the safety of vehicle–bridge system. Wang et al, 18 Li and Ou, 19 Ni and Xia, 20 Zhao et al, 21 Zhu et al, 22 and Erazo et al 23 investigated the state evaluation methodology of the existing bridge structure based on the SHM system.…”

“…3 Numerous studies have been conducted on the topic of structural condition monitoring for facilities subjected to external loads, including traffic loads and temperature changes. [4][5][6] Specifically, sensor data-driven structural condition monitoring methods have been frequently studied 1,7 as large datasets of structural responses (e.g., deflection, strain, and acceleration) and external loads (e.g., traffic loads or temperature) have become available with the rapid development of sensing technology.…”
