Abstract:
Based on the theory of Volasov and Housner, the shel-l bar aqueduct dynamical analysis modal with fluid-structure coupling and shear lag is established. The element stiffness and the mass matrix of the aqueduct are derived by an energy principle. The analytical solution formulas are deduced in the cases of no water and the design water level in aqueduct. By using the modal the frequencies in several cases are calculated and compared. The result shows that the frequencies are changed in the two cases. The modal in this paper is simple and pract-i cal for dynamic analysis of the fluid-structure coupling aqueduct .
