ARMADURA PARA ESTRUTURA DE CONCRETO ARMADO: comparação de custo entre fornecimento do aço em barra e pré-armado

Abstract

This article deals with the supply of reinforcement steel for reinforced bars and pre- reinforced concrete structures, aiming to prove the cost reduction with the supply of pre- reinforced steel weapons for a building in the south of Minas Gerais. For this purpose, a literature search was conducted for two forms of steel supply, and subsequently using a tower structure model of a constructed pavement building, if a comparative case study of costs among steel bar suppliers and the pre-armed. Then, for cost or budget analysis, it will be based on cost composition adaptations arranged in TCP (Budget Price Tables). An analysis of the economic viability of the proven types of supplies that precast steel yields a 6% reduction in total frames reduces material loss by 5% and labor time by 25%. The article provides a foundation for construction professionals who do not allow the management of weapons execution for reinforced concrete structures.
