Open publisher page 1 citations

Abstract

Seismic response behaviors of long-span concrete filled in steel tube(CFST)deck-type arch bridge were investigated.The free vibration specialty between half-through CFST arch bridge and CFST deck-type arch bridge was contrasted.The seismic response behaviors of CFST deck-type arch bridge subjected to longitudinal excitation,vertical excitation and lateral excitation were analyzed by timehistory analysis method.The effect of multi-support excitation was also discussed,and the seismic response specialty was contrasted between CFST deck-type arch bridge and CFST half-through arch bridge.
