“…Wang et al (2019i) investigated the interaction of water with multiple circular cylinders under the earthquake and incident linear waves using the finite element models and proposed the simplified formulas of the added mass coefficients of pile group. Moreover, Deng et al (2019) study the individual and combination influences of pounding and fluidstructure interaction on a typical deep-water bridge with hollow piers. In Yang et al (2020a), an analytical calculation method of hydrodynamic force on pile group is proposed Yang et al (2020b) deduced the analytical calculation method of the hydrodynamic force on twin columns of deep-water bridge.…”

“…The calculation model diagram is shown in the Fig 3, and the data of the fluid-structure interaction surface is exchanged through System Coupling. The pressure-based transient model is selected for the solver type in Fluent, and the VOF method is used to divide the entire fluid domain into the gas phase and liquid phase [22,23], while considering the surface tension coefficient of the liquid (Among them, the gas phase is filled with air and the liquid phase is filled with water). The calculation model uses K-epsilon in the turbulence model and uses the standard wall function.…”

At present, the crude fluid-structure interaction analysis model cannot accurately characterize the interaction mechanism between aqueduct and water under earthquake action. In order to solve this problem, this paper analyzes the seismic response of the double-tank aqueduct under the action of earthquake by using the shaker test and the VOF (Volume of Fluid) method considering the free liquid level from the perspective of fluid-solid bidirectional coupling, explores whether the liquid movement in the double tank is consistent and the shock absorption effect of different water levels on the aqueduct, and analyzes the amplitude of free liquid level sloshing and the change of horizontal dynamic pressure caused by water level change from the generation mechanism of TLD (Liquid tuning dampers). The results show that the liquid movement in the two tanks in the double-channel aqueduct is basically the same under the action of earthquake, and the TLD effect of the liquid gradually increases with the increase of the water level in the aqueduct, and the maximum peak shock absorption rate is 63.4% at the maximum peak and 50.4% in numerical simulation. The shaking amplitude of the liquid is positively correlated with the water level height, and the magnitude of the shaking amplitude also reflects the magnitude of the moving water pressure.

“…However, this study lacked the experimentation and analysis of large-scale flexible risers with high-order modal response and resonance, which can improve the accuracy of the interaction between real fluids and flexible risers. Deng [29] constructed a three-dimensional finite element model to study the longitudinal seismic response of bridges for the effects of the impact and fluid-solid coupling on bridge piers, and the study showed that the fluid-solid coupling effect was one of the causes of the impact in deep-water bridges, whereby the fluid-solid coupling amplified the seismic displacement of deep-water bridges. However, both fluid-structure interactions and individual collision effects of structures in the natural environment lead to an increase in bridge displacement; hence, the causes of bridge displacement should be explored in depth in deterministic analysis.…”

With the aim of determining the influence of the fluid–structure coupling dynamic effect of the oil and gas transmission medium and pipeline on the seismic response, an oil pipeline supported by a cable-stayed spanning structure was taken as the study object. Kinetic equations taking into account the action of oil and gas medium were studied, and a finite element model structure considering the additional-mass method and the fluid–structure coupling effect were established separately. In addition, the mechanism of the oil–gas–pipeline coupling action on the seismic response of pipeline structure was analyzed, and the results were obtained. The results show that the pipeline has a minimal seismic response at the abutment location, the seismic response gradually increases along the abutment to the main tower, and the seismic response reach is maximized at about one-fifth of the bridge platform. The seismic response of the oil and gas pipeline model structure using the additional-mass method is generally more significant than that based on the fluid–solid coupled dynamic model; moreover, the maximum displacement response differs by about 24%, and the maximum acceleration response differs by approximately 30%, indicating that the oil and gas medium has a certain viscoelastic damping effect on the seismic response of the oil pipeline, which provides a reference for the seismic response calculation theory and analysis method of cable-stayed spanning oil pipelines.
