Special Issue Information

Dear Colleagues,

Bridge infrastructures are incredibly valuable as forms of safe, resilient, and sustainable transportation networks. With increasing traffic demands and long-term exposure to harsh environments, bridge performance undergoes changes over time. This is accompanied by a decrease in reliability owing to the combined action of fatigue, creep, shrinkage, and corrosion. In extreme cases, the observed damage will pose a major threat to public safety if it results in the fracture of crucial load-bearing members, and may lead to the progressive collapse of a structure. Therefore, these potential risks make the fatigue performance assessment and fatigue life prediction of bridges and the safety analysis of degraded bridges under accidental loads, such as earthquakes, explosions, impacts, fires, and typhoons, an important proposition. Furthermore, the design and retrofit of the bridge’s members based on fatigue performance assessment and safety analysis is an effective method for ensuring the long-term and high-quality function of bridges, which is a concern.

In 2022 and 2023, we gathered dozens of excellent papers by researchers from America, Europe and Asia, and published them in the Special Issue "Advances in Bridge Design and Structural Performance". Following on from the success of this Special Issue, in 2024, we will once again collect papers for a Special Issue entitled "Advances in Bridge Design and Structural Performance (2nd Edition)", in which we are aiming to include research on all aspects of bridge design and performance assessment under long-term effects and accidental loads, including, but not limited to, steel bridges, concrete bridges, cables, girders, joints and connectors, accessory members, fatigue damage, creep and shrinkage effects, corrosion and fatigue, accidental loads, crack propagation, multi-factor coupling analysis, multi-scale simulation, time-varying reliability assessment, and so on. If you are interested in this topic and would like to share your work with us, please do not hesitate to contact us.

Based on a damaged continuous rigid-frame bridge in Shaanxi Province, this study deduced the crack damage simulation algorithm and the vehicle-bridge coupling numerical algorithm. Then, it established a finite element analysis model using ANSYS APDL. The Newmark-β iterative method was used to study the dynamic response of different speeds, vehicle weights, and damage degrees before and after the structural damage. In the analysis of the influence of different speeds, the results showed that the dynamic stress responses of key sections of the undamaged bridge reached the maximum when the speed was 80 km/h, indicating that the undamaged bridge was sensitive to a speed of 80 km/h. The peak response of the damaged bridge was 90 km/h. In addition, the displacement peaks and the stress peaks rose and fell together. The analysis of different vehicle weights and damage degrees showed that with the increase in them, the displacement and impact coefficients of each section increased significantly. It can be concluded that the dynamic performance of the in-service bridge decreases continuously with the aggravation of the damage. Therefore, the influence of vehicle-bridge coupling should be emphasized in maintenance, and the frequent cracking area at the midspan should be strengthened in time to prevent further damage.

This study introduces a novel Unmanned Aerial Vehicle-mounted (UAV-mounted) Laser Doppler Vibrometer (LDV) system for detecting debonding damage in Hidden Frame-Supported Glass Curtain Walls (HFSGCW). The established system enables UAVs to transport the LDV to high altitudes for operation. The vibration signals acquired by the UAV-LDV system are decomposed into different energy bands by wavelet packet analysis, and then the occurrence and location of the damage are identified by the Sum of Squared Differences (SSD) of the wavelet packet bands’ energy. This paper investigates the potential factors affecting the performance of the Unmanned Aerial Vehicle-Laser Doppler Vibrometer (UAV-LDV) system, including the arrangement of measuring points, measuring distance, noise level, and wind speed through the first-order natural frequency, the normalized frequency response functions, and the SSD indicator. Experimental and simulation results confirm the effectiveness of the UAV-LDV system, highlighting its advantages over traditional methods by offering remote, non-contact, and efficient debonding detection. This method not only indicates the presence of the damage, as traditional indicators do, but also pinpoints the exact location of it, ensuring safety and cost-effectiveness in high-rise inspections. The proposed method and indicator offer advantages in terms of convenience, visualization, and efficiency. The study discusses the impact of measurement point arrangement, measuring distance, noise levels, and wind speed on the system’s performance. The findings demonstrate that while the UAV-LDV system introduces new capabilities in rapid and reliable structural damage assessment, operational challenges such as wind and noise levels significantly influence its accuracy.

Earthquakes and floods in Albania are devastating, but combining these two different hazards in terms of action on bridge structures may lead the bridge to collapse. This article presents a seismic risk assessment of a code-conforming precast reinforced concrete bridge located in a region prone to earthquakes and where local scour induced by floods is a significant concern. The seismic action is considered using a group of ground motion accelerograms generated by matching the accelerogram of the 29 November 2019 earthquake in Durres (M = 6.4), Albania, to the target response spectrum. The scouring effects on the bents of the bridge are characterized by the scour depths. A set of non-linear time-history analyses of the bridge are performed to assess the bridge’s performance. The bridge fragility curves are generated and analyzed for multi-hazard scenarios at both element and system levels for different flow discharge values and PGA levels. The result shows a low seismic risk of the bridge with bearings when considering the local scour induced by flood events in the seismic analysis due to their flexibility to adapt to changes in structure geometry and significant foundation stiffness. This research also emphasizes the significance of choosing the right foundation type and depth for bridges located in areas prone to local scour induced by floods. Full article
