Finite Element Analysis of Influencing Factors of the Spherical Bearing Horizontal Offset in an Interchange Curved Bridge in Beijing

Abstract:

In order to ensure the safety of the curved girder bridge operations, the actual testing is necessary to determine the impact of various factors on the horizontal offset of the bridge bearing against bearing defects. In this paper, finite element analysis with Midas/Civil is applied to each factor separately to get the spherical bearing offset of various factors which compared with the actual displacement analysis, and get the impact the bridge itself gravity, the vehicle load generated by the centrifugal force and the temperature load to the spherical bearing horizontal offset. The analysis results show that the main reason of the spherical bearings horizontal offset is climb shift of the bridge in temperature load. On this account, make effective measures for the protection and repair of bridge to ensure the safety of the bridge operations.
