Estudo de viabilidade econômica do sistema light steel frame para construção residencial de alto padrão

Abstract

This work consisted of an economic analysis concerning the differences between the cost of materials in concrete and Light Steel Frame structures, focused on the sector of luxury housing. This research is justified by the need of development of alternative construction technologies, due to the high environmental cost of traditional concrete structures. The search for knowledge concerning Light Steel Frame construction consisted of instructions given by local professionals, reading of international literature on the subject, and Brazilian-made manuals. The actual research was done by selecting an already-built house made with a concrete structure – with a known budget – and creating a new, alternative structural project for it, using the Light Steel Frame system. The bulk of the project was created using a Brazilian software called mCalcLSF. After the structural analysis, the program created a list of necessary materials, that was used to elaborate the overall budget of the Steel Frame materials. After comparing both cases, it was concluded that the cost of materials of the original project was lower
