Análise comparativa da viabilidade da montagem de pavilhões em estruturas de aço, total e parcialmente parafusados

Abstract

The purpose of this work is the comparative analysis of the economic viability between two construction methods of steel structures, the first method being structures with partially screwed connections, which uses the processes of cutting, bending, drilling, welding, painting and assembly in the process of manufacture of the parts, to give rise to parts of the structure, which is later assembled on site by the screwing process. The second method, the structures with fully screwed connections, uses the same processes as the first method, but excluding the complete use of welding, with the assembly of all parts occurring on site, also by screwing. The comparative study was based on small, medium and large generic industrial halls, covering the initial stages of building construction, such as scope, fabrication, transportation, and assembly projects. The results were presented in order to compare the two methods listed, demonstrating the economic advantage between the construction methods exemplified by the 3 different types of work size. With a budget made in two different companies, afer comparing the methods, savings of up to 35% were achieved by excluding the weld, and the fully screwed method is the most economically viable.
