Análise estrutural e comparativa de custos entre uma cobertura hipotética em madeira e uma cobertura metálica projetada para um CMEI em Natal-RN

Abstract

In the execution of a work, good planning is necessary to avoid high costs in the final value. The roof is one of the most important items in the execution of the work, therefore, it is necessary constructive solutions aligned with its cost, in order to enable the best structure, in an economical and quality way. This work proposes to make a comparative structural and cost analysis between a hypothetical wooden cover and a metallic cover designed for the space of a Municipal Center for Early Childhood Education (CMEI), whose total area is 775.85 m², adopting a conventional construction system. The entire dimensioning of the wooden structure roof was carried, following the Regulatory Norms and using programs such as Ftool and Excel, while the structural design of the metal structure roof was obtained through the construction company responsible for the execution of the work. Thus, at the end of the study, it was possible to determine that roofing in a wooden structure has a higher cost than expected, making its application economically unfeasible for the project in analysis, being a roofing in metal structure much more economical.
