| Abstract: | In this paper,pseudodynamic test and numerical analysis of a double-deck viaduct were performed.The restoring force model,ductility capacity,strength,stiffness characteristics and collapse mechanism of the viaduct are investigated and discussed.It's shown that test results can be predicted through an equivalent bilinear restoring force model,and if the double-deck viaduct is designed appropriately,satisfactory seismic performance can be expected. |
