Abstract
The scouring of piers bridges, caused by hydraulic action, is one of the main risks that the structure suffer over the years. One of the methods in development is to change the structure of the bridge incorporating a upper cable-stayed arch, which allows to implement vertical and network hangers in charge of lifting the original bridge board. For this it is necessary to optimize the order and the adjustment magnitudes tension of the hangers. To solve this problem we implemented a software for optimization which uses Galactic Swarms Optimization, which is inspired by the movement of the stars, which is inspired by the movement of the stars, galaxies and superclusters under the influence of gravity. When comparing the results obtained with other approximate techniques, we can observe from the diagrams of distribution of instances that level two of the algorithm does not have the necessary and expected capacity to solve or leave from a local optimum.
