Sci. 2021, 11,2 ofare not simply subjected to constant load (i.e., structural weight) at the same time as alternating loads (i.e., temperature, vehicles, wind, etc.), but additionally corrosive situations which include humidity, high chloride ions, and changing temperature [9,10]. These complex components can lead to the service life in the hangers (eight 16 years) being much shorter than their design and style life (i.e., 20 years) . Hence, hanger replacement is often a incredibly prevalent measure inside the Uridine 5′-monophosphate Cancer repair method of arch bridges . Even beam bridge Bismuth subgallate custom synthesis structures including reinforced concrete bridges or steel bridges will fail or collapse as a result of material degradation, and some essential maintenance and reinforcement measures have to be taken for the duration of their service period . In China, greater than 30 out of more than 600 arch bridges have undergone the hanger replacement process [12,20]. Using the extension of service life, there will probably be a lot more arch bridges that need to have hanger replacement. The frequently used hanger replacement approaches incorporate the short-term bracket method, short-term hanger system, and pocket hanging strategy, of which the pocket hanging technique has been broadly utilized because of its positive aspects including a clear conversion program, reasonable structural force, and no need to have to close traffic . Suspenders are vital force transmission elements in suspension and arch bridges, which connect the girder towards the most important cable/arch. In current years, plenty of investigation has been carried out on problems related to cable replacement of cable-stayed bridges and suspension bridges. Hossain et al.  summed up a cable replacement process for thae suspension bridge. Ferreira et al. [23,24] and Simoes and Negrao et al.  presented an optimization algorithm to solve the structural-control style trouble of cable-stayed bridges and carried out the static, dynamic, and erection stage analysis simultaneously. Hangers must be replaced promptly when severe harm happens. Sun et al.  proposed a replacement method utilizing short-term hangers and performed field implementation of hanger replacement for a suspension. To be able to make certain the safety and reliability of your cable replacement, reasonable mechanical analysis and construction control must be carried out around the cable replacement course of action. Yao et al.  adopted the finite element approach on Tianjin Yonghe bridge to simulate each and every stage on the cable replacement course of action; the dates of tension, the alignment of the main beam, plus the alter of pressure just before and following the cable replacement have been compared and analyzed. Sun et al.  made use of Kalman’s filtering technique inside the building control for cable replacement combined with the cable replacement project of Jiao-Ping Du cable-stayed bridge. The outcomes showed that the cable tension of the cable-stayed bridge was 2926 kN much less than the style cable tension after changing the cable of this bridge. Furthermore, considering the sustainability of secure operation during the whole life of your structure, the optimization design of cable structures has progressively attracted attention. Brown et al.  described the work to replace all 72 from the keep cables in the Hale Boggs Memor.
