ESTUDO DE CASO: CONCEPÇÃO E DIMENSIONAMENTO DE ESTRUTURAS METÁLICAS PARA UM GALPÃO NA CIDADE DE RIO VERDE – GO

Abstract

In the city of Rio Verde - GO, it is common to use metal sheds for various purposes, but many of them are carried out without projects, with unskilled labor and without monitoring by professionals. In this way, the inadequate design and the inefficient dimensioning of metallic structures appear as a problem that leads to an excessive use of constructive resources. In view of this, structural optimization becomes a solution for reducing the weight of structures, resulting in savings in material and financial resources. The objective of this work was to dimension the metallic structure of an industrial shed built in the city of Rio Verde - GO, to verify a possible replacement of the existing structure in the place. The methodology adopted consisted of the design, dimensioning and analysis of four structural models, complying with the criteria established by the current safety standards. Free-use programs or demo versions of commercial software were used to analyze the models. At the end of the study, the model that consisted of a shed with pillars formed by a truss column and flat trapezoidal roof became the lightest model, generating a savings of 54.11 % in steel consumption in relation to the reference structure, thus explaining that a well-conceived and optimized project can generate savings in resources while executive problems on the job can be reduced, ensuring the longevity and functionality of the structure.
