According to Dawenkou bridge, a seriously deteriorated rigid-frame arch bridge, typical deteriorations of rigid-frame arch bridges were summarized. Based on 3-dimensional finite element model of a rigid-frame arch bridge, the relationship between dynamic properties and deteriorations of the structure, especially the influence of lateral tie system on the dynamic properties of the structure was analyzed. The results show that, damages of lateral tie system in operation induced premature appearance of lateral vibration directly; however, the large curvature torsion of deck obviously should take the mainly responsibility of damages of lateral tie system. According to the above analysis, the corresponding reinforcement scheme and specific measures were proposed.
