“…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. Wei et al (2019e) assessed the dynamic responses of the deepwater rigid-frame bridge by underwater shaking table tests and numerical simulations and proposed a practical method for seismic design of deepwater rigid-frame bridge.…”

“…To investigate the effect of water-structure interaction on bridge, the added mass method as discussed in Section 2 is adopted in many studies. Li and colleagues [124][125][126] analyzed the dynamic responses of bridge considering the hydrodynamic force by the added mass method. The results indicated that added mass method was an effective method for nonlinear and linear dynamic analysis of bridges considering water-structure interaction.…”

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.

“…For the pile group foundation of pylons located in seawater and soil, the SSI effect is simulated using p-y spring models according to the formulae suggested by API, 27 and the added mass is calculated using the Morison equation and potential flow theory to consider the hydrodynamic effect. 28 The pile cap is generally assumed to be a rigid body under seismic excitations; thus, it is modeled by the lumped mass and connects the piles with rigid links. Because the piers are located on the rocky site, the piles for the piers are neglected and fixed constraints are used to the base of the piers in this study.…”

The coastal or sea‐crossing bridges located in seismic regions are experiencing long‐term chloride‐induced corrosion in their life cycles and have a high risk of suffering from strong earthquakes. Thus, the fragilities of these bridges must be properly evaluated under the multiple hazards of corrosion and earthquake. Conventional fragility assessment requires expensive computational efforts despite extensive applications in previous research. To this end, this paper proposes a life‐cycle fragility analysis framework based on the endurance time method to investigate the deterioration impact on the seismic fragility of bridges. An example sea‐crossing cable‐stayed bridge is utilized as a case study and modeled by OpenSees considering different service years. The life‐cycle fragility curves of the example bridge are generated using the artificial endurance time series. Fragility analysis results show that the proposed method is capable of assessing the life‐cycle seismic fragility of the bridge with high efficiency. The bearing shows a higher damage probability than the pylon and pier. As the service time increases, the structural deterioration has a marginal impact on the system fragility of the bridge, while the component fragility varies across different components. The structural deterioration results in beneficial effects on the pylon and the bearing at the pylon but exerts adverse effects on the pier and the bearing at the pier.
