| Abstract: | The nonlinear time history analysis is made on the seismic performance during rare earthquake for an aqueduct which is one of the typical aqueducts to cross the main trunk canal of the Mid-nroute of the South-to-North Water Transfer Project in China. The section fiber model is used in the numerical analysis; of which the result shows that no any weak portions are occurred in the structure of the aqueduct supporting frame concerned. Therefore, the seismic performance of the aqueduct is satisfactory to resist the rare earthquake with high intensity therein . |
