| In this paper, track-bridge interaction finite element models of both a three-span continuous beam bridge and a simply supported beam bridge were established in order to study the influence of creep camber on the track-bridge interaction in railway bridges. The effects of creep camber on additional rail stresses (ARSs), the uplift and shearing force of fasteners, and the train running performance of continuous welded rail (CWR) on bridges were analyzed. The results show that for the limit value of creep arch based on beam-rail interaction, the uplift force of fasteners and driving comfort play a controlling role, while the effect of ARSs is relatively insignificant. For beam bridges with the same arch-span ratio, the peak values of ARSs, uplift force and shearing force of fasteners induced by creep camber are basically the same. For the continuous beam bridge with a main span of 125 m and the simply supported beam bridge with a span of 30 m in this paper, the reasonable limit value of the arch span ratio of creep camber should be 1/2 500 and 1/2 000 respectively.
