Abstract
Abstract
Aqueduct, one special kind of bridge, has quite different loads from traditional bridge. In this paper, we study the fluid-structure interaction characteristics of a steel truss aqueduct under seismic force using finite element method (FEM). The additive mass method is used to get the acceleration of key sections under E2 earthquake wave. Then the acceleration is applied on the FSI model to obtain the influence of unbalance hydrodynamic load and hydrodynamic pressure on structure. A simplified linear relationship between earthquake acceleration and pressure on the wall is also proposed. The conclusions and approach provided by this study could serve as significant references for anti-seismic design and control of similar steel truss aqueducts.
