Abstract Research purposes: The Yili River Bridge is an important project to connect the 218 National Highway with313 Provincial Highway and is the largest bridge in Xingjiang with main bridge of coupled thin wall continuous rigid frame bridge(66 + 5 × 120 + 66) m． It is located in 7 degree earthquake region． As there is a little research on the seismic response of long span continuous rigid frame bridge is very rare ，it is necessary to research the seismic response regulations of this bridge to make sure the bridge safety and provide the reference to the similar works．

Research conclusions:From the analysis it is concluded (1) For the continuous rigid frame bridge，the plastic hinges region is on the top or bottom of frame pier and where need to be strengthened． (2) Under the seismic reaction，the plastic hinges happen to this bridge，but they keep certain away from the damaged displacement． (3) The Yili River Bridge has enough ductility and it can not fall under the serious earthquake．

Key words： continuous rigid frame bridge seismic response time － history analysis moment － curvature relation plastic hinges
