Seismic Response Analysis of Horizontal in Nilka Ditch Aqueduct

Aqueduct is a kind of essential water-carrying services for carrying water across railways, highways, rivers, valleys and other important facilities. In addition to transmission of water, it is also used in the flood discharge, diversion and so on. It is an important cross-building in the water delivery, water supply and channel system and is normally the building control in the canal system. Three-dimensional finite element model of Nilka Ditch aqueduct is established, then aqueduct structure is analyzed in modal. Nilka Ditch aqueduct in the different conditions is analyzed used the static method and the seismic response spectrum analysis on the horizontal seismic response analysis based on the natural frequencies and mode shapes. The proposed seismic is recommend reasonably by comparing the results.
