In this paper, the effect of selection of response parameters such as deck displacement and supporting moment on impact factor of open spandrel-concrete deck arch bridge is investigated by using a finite element analysis. In the result, under the vehicle loads passing the bridge from left to right direction, the highest value of impact factor develops when the supporting reaction moment at the far end (right end) of arch rib is selected.
