Evaluación de alternativas para mejorar el desempeño de columnas del paso elevado de la av. 25 de Julio intersección vía Perimetral.

Abstract

The piles of an overpass must remain in optimal condition for the support of loads with which they were designed, years ago many bridges / overpasses of the city of Guayaquil were designed by regulations corresponding to the year of construction, with the passage of time, these standards are updated and considered a new way to analyze these loads. In the overpass of Av. 25 de Julio located in front of the Riocentro Sur of the city of Guayaquil, two piles were analyzed, one of low height and another of big height, obtaining their structural values through an analysis of the SAP 2000 program, which were of vital importance to develop the pertinent calculations and observe the behavior of both piles against their respective design loads, establishing a comparison of the regulations used at the time of construction of the year 2000 against a more current regulation of the year 2017, where the necessary reinforcement of these piles was concluded by means of a jacketing of structural steel A-36 for a state where their R values are reduced forcing the structure to take on greater load in elastic ranges and thus also be able to reduce its deformations. The cost required to opt for this new alternative is $ 48'224.57 where different thicknesses of steel with 20 and 30 millimeters are used for the #2 and #12 pile respectively.
