| Abstract: | With the FEM software ANSYS, this paper creates a spatial model of a prestressed concrete continuous rigidframe bridge located in seismic areas with element BEAM188, Dynamic characteristics of this bridge are analyzed; seismic responses under transverse or longitudinal excitation of 50years 296 and 10% transcendental probability are calculated using spectrum analysis method and time - history analysis method respectively; and internal force response and displacement response of crucial sections are obtained. |
