Research on Bearing Replacement Layout of High Pier Longitudinal Slop Continuous Bridge Based on the Seismic Response
A 160 meters four-span prestressed concrete box girder, whose design longitudinal slop is about 3％, has been slide down along the longitudinal direction soon after the bridge completion. So all of the damaged rubber bearings need to be replaced and the fixed bearings location need to be reconsidered. The finite element software MIDAS/Civil is applied to calculate the bridges static and dynamic properties. Two bearing replacement programs are compared, one is the symmetric fixed bearing program and the other is the non-symmetric fixed bearing program. According to the bridges temperature deformation results, the bridges dynamical characteristics, and the bridges seismic response results support to design earthquake action, it can be obtained that the more reasonable bearing replacement program is the non-symmetric fixed bearing program.
