| Abstract: | In this paper,the three-dimensional finite element model(FEM) of a large-span prestressed concrete continuous rigid-famed bridge is established by using the general purpose finite element program ANSYS.The modal analysis in the FEM is performed to get the theoretical dynamic characteristics and the field test under ambient vibration of the bridge is also performed to get the dynamic characteristic testing result.Some important conclusions are obtained by comparing the theoretical result with the testing result. |
