| Abstract: | Combined with the structural design of the roof truss-arched drainage aqueduct on the left bank of the main channel of the Mid-route of the South-to-North Water Transfer Project through Hebei Province, a FEM dynamic analysis model for the roof truss-arched equeduct is made under the consideration of the fluid-structure interaction; with which the self-vibration properties are studied under different loading conditions. The seismic responses of the aqueduct are calculated by the method of response spectrum, The analyses on the distributions of dynamic stresses and displacements of the main arch ring, the longitudinal wall of rectangular tank, the longitudinal beam and the bottom slab are made. The study lays a calculation basis for the engineering de- sign of the project concerned. |
