To make sure the safety of the hanger replacement within the construction method of pocket hanging, the structural response in the entire building procedure demands to be precisely controlled. Within this paper, aiming at half-through Lufenuron Inhibitor arches using a suspended deck by cable hangers, the precise displacement controlling technique for hanger replacement of an arch bridge depending on the pocket hanging method has been proposed. Firstly, the equivalent model of an arch bridge inside the hanger replacement course of action is established, and the boundary circumstances with the equivalent model are calculated precisely. Secondly, in the hanger replacement course of action, including old hanger demolition and new hanger installation, the precise displacement expressions on the suspended deck are derived on the basis of your equivalent model. Finally, the correctness and feasibility on the proposed precise displacement controlling method are verified by the hanger replacement engineering of an arch bridge. Through this study on the hanger replacement of an arch bridge, the equivalent model adopted within this paper has been established precise, and only partial boundary situations must be deemed in sensible engineering applications to acquire accurate outcomes. Meanwhile, the calculation outcomes are precise adequate by way of the sensible engineering verification, and also the precise displacement controlling strategy is feasible within the hanger replacement process of an arch bridge depending on the pocket hanging system. It’s also identified that satisfactory benefits can be achieved working with hanger demolition and installation by equal step length.

Introduction Arch bridges happen to be broadly used for their extreme competitiveness amongst numerous forms of bridges as a result of their positive aspects, like a big spanning potential, a attractive shape, and reasonable structural force [1]. As outlined by an incomplete survey, over 600 arch bridges have already been built in China, in which the load should be transmitted through the hanger regardless of whether it can be half-through or through the arch bridge. Among the hanger components of an arch bridge, hangers transmit wind or live loads around the deck for the primary rib, which are then transmitted for the earth. Hanger safety is therefore straight associated to the security of your complete bridge [5]. A hanger is normally created as a replaceable aspect, and their design and style life is a lot shorter than the design and style life with the bridge structure.
