Diseño y optimización geométrica de vigas alveolares de acero para pórticos simples de luz mayor a 10 metros

Abstract

In the present document a tool for the design of cellular beams for simple frames of span greater than 10 meters was developed. All of this because the use of universal beams following traditional design methods, combined with the lack of technological innovation has led to heavy structures with high assembly times characteristics that are reflected in higher costs for the structural solution. It began with a bibliographical review on the methods of design of cellular beams; the AISC Design Guide 2 was selected. An optimization method was used to get the best dimensions for the openings in the web. A programming code was developed that allowed to obtain the dimensions of the openings for a given beam under linear load conditions. A static analysis of the alveolar beams obtained from the application of the design tool, with materials with linear behavior, in order to verify that the efforts reached did not exceed the yield limit of the material was also realized.
