Analise comparativa de sistemas construtivos, alvenaria, steel framing e wood framing, em unidades habitacionais de interesse social

Abstract

This study analyses the constructive systems – masonry, steel framing and wood framing – with the objective of defining which, among them, is the most appropriate for the construction of social interest housing units in big quantity on the PMCMV. The brazilian housing deficit is a serious issue that require specific programs to be controlled and suppressed. Presently, the PMCMV is the tool used by the Brazilian government to reduce this housing demand. Still in this context, is approved the NBR 15.575, determining the performance brazilian buildings should reach. With the rules of this regulation and the standards defined in this study, the constructive methods were analyzed. As results of this evaluation, was found that: neither one of the constructive systems reached all the requirements, related to acoustic and thermal performance, of the norm NBR 15.575-4; and that, according to the parameters established in this study, both constructive methods, steel framing and wood framing, are suitable to the construction of social interest housing units in big quantity on the PMCMV.
