“…Zhang, Yu, Zhang, Wu, & Li, 2019), the effect of crosswind on vehicles is more obvious. In addition, complex and changeable environment will make the loads acting on bridges more complex (Ti, Zhang, Li, & Wei, 2019;J. Zhang, Wei, & Qin, 2019), thus, high-sided lorries, trucks and travelling buses are under risk of rollover when running through long span bridges (Chen & Cai, a) b) 2004; Coleman & Baker, 1990Xiang, Li, Chen, & Liao, 2014).…”

Aerodynamic characteristics of vehicles are directly related to their running safety, especially for the high-sided vehicles. In order to study the aerodynamic characteristics under multiple sheltering conditions, a complex large scale (1:20.4) truss model and three high-sided vehicles including articulated lorry, travelling bus and commercial van models with the same scale were built. The aerodynamic coefficients under various sheltering effects of wind barriers with different heights and porosities, bridge tower and the vehicle on the adjacent lane were measured. According to the results, wind barriers can effectively reduce wind speed behind them, thus decreasing the wind load acting on the vehicle, which causes the decrease of the aerodynamic response of all three vehicles. However, the influence at the leeward side is limited due to installation of central stabilizers. When the vehicle passes through the bridge tower, a sudden change occurs, the aerodynamic coefficients decrease and fluctuate in varying degrees, especially for the commercial van. When the vehicle moves in different lanes behind the bridge tower, the sheltering effect of the tower on the aerodynamic coefficient in Lane 1 is much greater than that in Lane 2. With regard to the interference between two vehicles on the adjacent lanes, the relative windward area between the test vehicle and the interference vehicle greatly affects the aerodynamics of the test vehicle.

“…Many new achievements of earthquake-induced fluid-structure interaction that is critical in the seismic design of deepwater bridges, have been made in 2019. Zhang et al (2019g) developed an efficient potential-based numerical model to determine the hydrodynamic added mass for immersed column with arbitrary cross -section. Zhang et al (2019f) also employed potential-based fluid elements to set up a threedimensional numerical fluid-structure interaction model to account for the hydrodynamic effects of a nonuniform bridge hollow pier submerged in a reservoir.…”

Deep‐water bridges are susceptible to severe damages under strong earthquakes. Water–structure interaction will considerably affect the dynamic performance of deep‐water bridges. In the past few decades, researchers have conducted extensive studies on the water–structure interaction and dynamic behavior of bridges through theoretical, numerical, and experimental investigations. This paper presents a comprehensive review on the calculation method for earthquake and wave‐induced hydrodynamic forces. The seismic responses of deep‐water bridges under individual or combined excitation of earthquake, wave, and current are discussed to explore the influence of water–structure interaction on the seismic capacity of deep‐water bridges. Finally, the development of testing facilities that can simulate the water–structure interaction is summarized. Particularly, a new multifunctional dual underwater shaking table system built‐in Tianjin University that can simulate multiple‐support excitation and water–structure interaction simultaneously is introduced in detail for the first time.
