| Abstract: | The basic conception of a chorded steel-concrete composite arch bridge is introduced.And its dynamic characteristics and structural performances are discussed.Its response to earthquakes is calculated by means of time-history analysis method,and the comparison of that with the general concrete ribbed arch bridges has proved that the chorded steel-concrete has a stronger resistance to earthquakes,so it can withstand stronger earthquake,comparing with the general concrete ribbed arch bridges. |

| Keywords: | steel-concrete composite arch bridge dynamic characteristic seismic performance |
