Abstract
By using the finite element analysis software Midas/Civil, two types of models of concreted-filled steel tube arch bridges with and without shock isolation were established. By considering the longitudinal travelling wave effect of the bridge, the different response values of the arch ribs and piers of the two models were compared under the wave velocity of 100 m/s, 500 m/s, 2 000 m/s, and longitudinal consistent seismic excitation, respectively. It is concluded that because the travelling wave effect of different wave velocities is complicated, the models both have good isolation effects for different wave velocities.
