A Seismic Study of Liquid Filed Aqueduct Considering Soil-Structure-Fluid Interaction

The paper presents study of the seismic response of the ground-supported fluid-filled rectangular aqueduct. The paper provides the theoretical basis hydrodynamic response of the fluid on the solid domain of the aqueduct, specifically focusing on the impulsive and the convective actions of the fluid in the aqueduct during an earthquake. The numerical simulations using the Finite Element Method (FEM) in software ADINA was used for solution of the problem. The first solution simulated only solid domain by finite element using the FEM and the fluid filing is presented by pressure effect given analytical and the second solution was simulated the fluid filling and solid domain by finite element using the FEM, Arbitrary Lagrangian Eulerian, and Fluid Structure Interactions. The results obtained using the analytical methods and numerical simulations for the liquid-filled aqueduct grounded on sub-soil are summarized and compared.
