“…Therefore, it would be necessary to conduct a comprehensive analysis of cable replacement that considers cable corrosion, damages, and even fractures during operation in the scheme design stage [6]. The cable replacement should be designed on the premise of minimum impact on normal traffic during cable replacement to minimize maintenance costs [7]. The removal of old cables and the re-tensioning of new cables during replacement inevitably lead to changes in the stress indicators of the bridge structure, including the bridge deck alignment, girder stress, and residual cable forces, which cause the redistribution of the internal forces of the cablestayed bridge and adversely affect the bridge structure itself [8].…”

Cable replacement is a key technique to solve the problems of cable corrosion and strand breakage. Cable removal causes structural changes. The choice of replacement method affects the safety of the bridge during cable replacement. A sensitivity analysis method was used to evaluate the force and deflection changes of Wohu Bridge. A reasonable method for the number and order of cable replacement was proposed; by comparing different cable removal schemes, it was revealed that the cable force and beam stress changes of the cables closest to the removed cable were the most significant. The results showed that the cable force increment of the surrounding cables was the largest when removing the longest cable. The structural impact change was small when removing the shortest cable. The maximum deflection at the top of the tower decreased with the decrease of the length of the removed cable. It was recommended to replace two cables symmetrically from the center of the tower, and the optimal replacement order was from the shortest cable to the longest cable. Furthermore, this paper also studied the influence of variable load on the cable replacement scheme, and demonstrated that the design scheme of opening part of traffic in this paper was safe and feasible.

“…Yao et al [26] adopted the finite element method on Tianjin Yonghe bridge to simulate each stage of the cable replacement process; the dates of tension, the alignment of the main beam, and the change of stress before and after the cable replacement were compared and analyzed. Sun et al [27] used Kalman's filtering method in the construction control for cable replacement combined with the cable replacement project of Jiao-Ping Du cable-stayed bridge. The results showed that the cable tension of the cable-stayed bridge was 2926 kN less than the design cable tension after changing the cable of this bridge.…”

The hanger often needs to be replaced many times during the operation period of hanger arch bridges. To ensure the safety of the hanger replacement in the construction process of pocket hanging, the structural response in the whole construction process needs to be precisely controlled. In this paper, aiming at half-through arches with a suspended deck by cable hangers, the precise displacement controlling method for hanger replacement of an arch bridge based on the pocket hanging method has been proposed. Firstly, the equivalent model of an arch bridge in the hanger replacement process is established, and the boundary conditions of the equivalent model are calculated precisely. Secondly, in the hanger replacement process, including old hanger demolition and new hanger installation, the precise displacement expressions of the suspended deck are derived on the basis of the equivalent model. Finally, the correctness and feasibility of the proposed precise displacement controlling method are verified by the hanger replacement engineering of an arch bridge. Through this research on the hanger replacement of an arch bridge, the equivalent model adopted in this paper has been proven accurate, and only partial boundary conditions need to be considered in practical engineering applications to get accurate results. Meanwhile, the calculation results are accurate enough through the practical engineering verification, and the precise displacement controlling method is feasible in the hanger replacement process of an arch bridge based on the pocket hanging method. It is also found that satisfactory results can be achieved using hanger demolition and installation by equal step length.

“…Cable-stayed arch bridge without back cable is a new type of bridge structure which combines backless a cable-stayed bridge with an arch bridge. It has the characteristics of backless cable-stayed bridge and arch bridge, and its unique shape gives people a unique aesthetic feeling [1][2][3]. The cable-stayed structure can balance the dead weight of the main girder by the inclined bridge tower and enhance the longitudinal bending resistance of the main girder.…”
