Dynamic Response Analysis of Reinforced Concrete Suspension Bridge under Seismic Action

Abstract:

Taking the typical reinforced concrete stiffening truss suspension bridge as example, finite element analysis model under seismic action is established. Dynamic response analysis is done on this suspension bridge using finite element software ANSYS and contrast is done between this analysis result and structural response under gravity load effect. Contrast result shows that structural response under seismic action is obviously higher than that under gravity load effect in which internal force response is greater than displacement. The function of dynamic load should be taken into account in the design of bridge structure in order to provide reference for the structural design of long-span flexible bridge.
