Nstall the new hanger by the finite element simulation. Nonetheless, only a smaller level of calculation time was required to utilize the proposed process. In the identical time, the results calculated by this process had been closer for the measured values than the FEM, and the maximum error was only -3.94 . Therefore, it was proved that the proposed method is quickly and accurate.Table 4.

Conclusions The precise displacement control of your bridge deck at the reduce end from the hanger is quite critical during the hanger replacement process of half-through arches with a suspended deck by cable hangers by utilizing the pocket hanging system. The process of hanger replacement based on precise displacement handle is proposed within this paper. Firstly, the variation coefficient of shear versus displacement on each sides of the hanger to be replaced have been calculated as well as the hanger was separated in the general model to be able to establish the equivalent model of your hanger to become replaced. Secondly, the structural response in the hanger replacement course of action and the new hanger installation procedure were obtained around the basis of the equivalent model. Lastly, an N-Hexanoyl-L-homoserine lactone Purity & Documentation actual hanger replacement of an arch bridge was adopted to confirm the correctness and feasibility of the proposed technique. The following conclusions might be drawn: (1) The adopted equivalent model of hanger replacement by separating from the general model in this paper was correct, and only partial boundary situations have to be thought of in practical application to have correct results. Within the hanger replacement process of an arch bridge based on the pocket hanging approach, the cumulative displacement improved and decreased alternately, plus the corresponding variation values were essentially exactly the same throughout the new hanger installation process applying equal step tensioning and unloading, which would accomplish a satisfactory outcome and meet the requirements. Even though the trend on the finite element calculation benefits was constant with the measured results, the deviation between them was still big. By comparison, the calculated outcome using the proposed technique had been fast and precise enough through the practical engineering verification, and the hanger replacement was feasible below the precise displacement control.(two)(three)Appl.
