Alvenaria estrutural e estruturas em concreto armado convencional: uma análise técnico financeira em edifícios residenciais

Abstract

Due to the current financial situation, the market tends to find constructive solutions, technically and economically viable, for the final cost of the construction established the process. The structural masonry has been an interesting alternative to obtain buildings more economical and sustainable. On Brazil, the structural masonry has experienced a great impulse, therefore, the competitiveness makes the companies concerned about costs, searching for new materials. A method used on a large scale is the reinforced concrete, very common in the country, it allows the execution of great varieties of structures, with good resistance and easy execution. The present work demonstrates a technical and financial analysis between a building built in reinforced concrete and the same structural built in masonry, with concrete block. To make that comparative possible, the dimensioning of the building was realized using two methods, the first is athwart Eberick, for the reinforced concrete and using ABNT - NBR 15961-1 (Brazilian Association of Technical Standards, 2011) and ABNT - NBR 15961 - 2 (Brazilian Association of Technical Standards, 2011) for structural masonry. Using inputs results from dimensioning, a budget was implemented, using SINAPI compositions.Through the results we have a great advantage and, as such, the benefit to use structural masonry, in comparison with reinforced concrete in addition to financial viability, it was possible to observe, according to the existing literature, greater agility in the execution, with less waste of material.
