Study on wind-induced response of fluid-solid coupling system for high bent-type aqueduct

Abstract

Abstract. In this paper, the coupling responses of water and high bent-type aqueduct under wind loads were studied by the Arbitrary Lagrangian-Eulerian (ALE) method. The natural vibration characteristics and transversal displacement, stress, overturning force, overturning moment, and hydrodynamic pressure of water-aqueduct coupling system were comparatively analyzed under di erent conditions of water-depth, cross-section shape of aqueduct tank, and support bearing. The research results show that the isolated support changes the dynamic characteristics and reduces wind-resistant performance of U-shape aqueduct. Therefore, the dynamic performance is better under the e ect of the uctuating wind; however, the sti ness for U-shape aqueduct is smaller than that for the rectangular aqueduct, with the same water uxes.

Dynamic Analysis of Reinforced Concrete Water Tanks under Blast Considering Fluid-Structure Interaction

“…They demonstrated that the enlargement of the draft has been led to the increment of the angle of attack, the beam of the pressure source, and the height of the generated wave. Zhang et al [15] employed the Arbitrary Lagrangian-Eulerian (ALE) method to evaluate the coupling responses of water and aqueducts with high bent-type under wind loads. They proved that the isolated support altered the dynamic properties and reduced the wind resistance performance of the U-shape aqueduct.…”
