Research on Urban Bridge Design Scheme Based on Seismic Performance
Relying on the engineering background of Jinyu Bridge in Quanzhou City,this paper analyzes the seismic response of the main bridge and calculates the seismic performance of the main bridge based on the two design schemes of continuous girder bridge and continuous rigid frame bridge by MIDAS/CIVIL.The results show that the maximum bending moment of both design schemes under E1 and E2 seismic effects occurs in the pier bottom section of the center pier,and the seismic performance of the hollow slab pier continuous girder bridge under seismic effects is better after adopting the damping bearings.Seismic response becomes one of the main control factors for the design of continuous rigid bridge.Through the hollow slab pier bridge seismic response analysis and seismic performance research,for similar bridge design program se-lection to provide reference.
