Optimización y sistematización de procedimientos para determinar ejes equivalentes por el método AASHTO

Abstract

This project allows Optimizing and Systematizing the Equivalent Axis calculation processes, through a computerized proposal. The program was carried out in MATLAB R2020a, which shows a series of screens that facilitate the organization and data entry, which go through a calculation process to obtain the final result, the Equivalent Axes. The program contains a series of data and buttons that help the user to understand how and why the calculations are carried out, variables involved, formulas that were used and how the calculations were carried out in accordance with the Ecuadorian standards in force to date. The data used to verify the calculation process were taken from the thesis of the university repository of the Universidad Politécnica Salesiana, mostly. The ESTRAV program has been compiled into an executable so that it is easy to acquire and install, although it is recommended to use it in MATLAB R2020a. In this way, ESTRAV may be modified according to the user's needs, as long as the user has knowledge of programming (MATLAB's own “m” language) and Civil Engineering, specifically road design. ESTRAV obtains a minimum and maximum range of Equivalent Axes. When using exponential equations, the slightest variation of decimals causes large variations in the results, so all the values within this range are a solution to the calculation of Equivalent Axes and choosing one of these values is at the discretion of the user.
