| Abstract: | A large-span half-through arch bridge with concrete filled steel tube ribs arch ribs located in Fujian Province was studied in this paper,and the dynamic characteristics of this large span half-through arch bridge are calculated and analyzed by using a three-dimensional finite element model.In addition,three-dimensional seismic response of this bridge is obtained by the use of time history method.The effects of the longitudinal,the cross and the longitudinal cross direction input of earthquake motion on seismic response of this bridge have been discussed.This study provides a theoretical basis for the seismic design of large span half-through arch bridge with concrete filled steel tube ribs. |
| Keywords: | Half-through arch bridge seismic response dynamic characteristic time-history analysis |
