Research on Seismic Performance for Steel Box Arch Bridge Scheme of Xiazhang Sea-Crossing Bridge
Xia-Zhang Sea-crossing Bridge was located in earthquake zone, the design of which was governed by earthquake. Based on seismic-isolation principles, seismic-isolation bearing system and damper system were studied to find out the effect of each seismic-isolation system on seismic performance of steel box arch bridge scheme. Seismic response could be effectively reduced by damper system, without changing the original constraint system of structure, which was recommended for longitudinal seismic system. Two liquid viscous dampers were suggested installing between pier and girder after parameter analysis, with damping coefficient of 4000kN/ (m/s) 1.0 and damping index of 1.0.
