“…In this paper, this analysis is not included but the dynamic analysis is performed to properly assess the properties of the 95-year-old arch concrete bridge. It should be noted, that improper design of bridge structure cause the risk of excessive structural vibrations throughout the operation [ 68 , 69 , 70 , 71 , 72 , 73 ].…”

The structural analysis of a 95-year-old concrete arch bridge located in Jagodnik (Poland) is performed in this paper, in order to check its behavior under today’s traffic loads. The mechanical properties of both the concrete and the reinforcement are investigated by testing cores and bar stubs extracted from the bridge. Structural analysis confirms that the bridge meets today’s load requirements in terms of bearing capacity, serviceability state, and that the adopted structural improvements (a new deck slab on top of the existing structure and a layer of mortar to protect the surface of the old concrete) are effective. In this way, the 95-year-old arch bridge was given a new life. The structural improvements show how combining numerical modelling and laboratory tests can contribute to the preservation of an old—though fairly simple—and valuable structure, otherwise destined to demolition, with both environmental and economic benefits.

“…Focusing on various types of bridges, Lorenzoni, et al [13] investigated how the extraction of modal parameters is affected by structural topology, extraction duration, load, and environmental effect. Using the LAN XI dynamic test system proposed by Kilikevicius et al [14] analyzed the structural dynamic response of an old bridge, and acquired the main dynamic parameters of the bridge. Aras [15] performed modal tests on an overpass during the construction, and thus determined the transition of structural system.…”

This paper attempts to evaluate the actual carrying capacity and guarantee the operation safety of Qin Bridge, Ningbo, China. Considering the structural features of the bridge, reasonable field load plans were prepared to realize load test safety control of long-span through tied-arch bridges with single bearing surface (SBS-TTABs). The internal force, stress, and deformation control under different working conditions of static load were calculated, and compared with those measured in static load tests. After that, the natural vibration, and damping features of the target bridge under impact and bumping were explored through pulsating test, barrier-free driving test, and bumping test. The results show that the maximum deflection and strain measured on the midspan section and arch rib section were both smaller than theoretical values, the calibration coefficients of deflection and strain fell in 0.60-0.88 and 0.48-0.88, respectively, indicating that the overall rigidity and strength of the bridge meet relevant code. Under the test loads, the maximum relative residual deflection and the maximum relative residual strain at each measuring point were 12.98% and 11.76%, respectively. Both were below the 20% threshold specified in JTG/T J21-2011. It shows that the bridge span has excellent elastic recovery ability. In dynamic load tests, the fundamental frequency measured by driving test agreed with that measured by bumping test, and the vibrations were smaller than the theoretical values. This means the main span has stable vibration features. Overall, the target bridge has sufficient capacity to withstand Urban-A level vehicle load, under normal use conditions, and the bridge structure belongs to the safe state.

Structural health monitoring (SHM) systems have been developed to evaluate structural responses to extreme events such as natural and man-made hazards. Additionally, the increasing volume of users and vehicle sizes can lead to the sudden damage and collapse of bridge structures. Hence, structural monitoring and dynamic characteristic analyses of bridge structures are critical and fundamental requirements for bridge safety. SHM can overcome the weaknesses of visual inspection practices, such as lack of resolution. However, because of computational limitations and the lack of data analysis methods, substantial quantities of SHM data have been poorly interpreted. In this paper, the SHM of bridges based on dynamic characteristics is used to assess the "health state" of bridge structures. A comprehensive SHM system using vibration-based techniques and modal identification for bridge structures are well defined. Some advanced concepts and applications regarding bridge safety evaluation methods, including damage detection and load-carrying capacity, are reviewed. For the first time, the pros and cons of each vibration technique are comprehensively evaluated, providing an advantage to the authority or structural owner when developing a bridge management database. This information can then be used for continuous structural monitoring to access and predict the bridge structure condition.
