ANÁLISE COMPARATIVA ENTRE SISTEMAS CONSTRUTIVOS LIGHT STEEL FRAME E ALVENARIA CONVENCIONAL PARA A HABITAÇÃO DE INTERESSE SOCIAL DO MUNICÍPIO DE BOA ESPERANÇA/MG

Abstract

The objective was to compare, using a standard plan for a popular house, the conventional masonry construction systems and the Light Steel Frame (LSF), using the criteria of speed of execution, economic advantage and better environmental suitability. It was justified, as Civil Engineering is challenged to propose more successful construction methods to combat the Brazilian housing deficit. We opted for an exploratory study, choosing the Minas Gerais municipality of Boa Esperança, considering its geographic positioning, local tourism and population growth, imposing the need for urban housing. Data was collected on the quantity of materials, costs and work execution schedule for the two construction systems. Although the results obtained demonstrated that LSF results in higher value/cost compared to the conventional masonry system, its operational properties (reduction in work execution time, little waste generated resulting in lower environmental impact, agility and labor qualified, technology in the process through industrialization offered) demonstrate great effectiveness. This statement is based on rationalized technology, with a structure built from profiles formed from galvanized steel wire, whose organization takes place in structural and non-structural panels, enabling dry construction, with great speed of execution. It was then concluded that despite the results of the comparison between the conventional masonry system, it shows a lower cost of 18.38%, even so, considering the ability to fulfill the socio-environmental proposals involved (promotion of sustainability and

reduction of the housing deficit) , the LSF system would be the most ideal for social housing projects.
