摘要：
The resonance mechanism of wind-induced aqueduct-water coupling system installed with isolated bearings was studied using the Arbitrary Lagrangian-Eulerian (ALE) method and the Finite Element Method (FEM). A water sloshing model was used to analyze the dynamic properties of a U-shaped aqueduct-water coupling system. Simulation results show that the resonance can be eliminated under high-order-frequency excitation and may happen when the excitation frequency is close to the first-order water sloshing frequency. Though the isolated rubber bearings are helpful to improve the earthquake resistance capacity proposed by Zhang et al. (Zhang H, Liu L, Dong M, Sun H. Analysis of wind-induced vibration of fluid-structure interaction system for isolated aqueduct bridge. Eng Struct 2013:46:2837), they reduce the structural stiffness, lengthen the structural vibration period and reduce the wind resistance performance of aqueduct structures. (C) 2013 Elsevier Ltd.
