Estudo de comparativo entre estrutura de concreto armado e estrutura metálica mista na construção de edifício comercial

Abstract

This study aims to analyze a comparison between two commercial works performed with different building systems for the design of its structure, the first work being made of reinforced concrete structure and the second work being made of steel structure with steel deck slabs. The comparative analysis of the structure refers to the gains and losses of the systems in relation to time and costs, presenting its particularities, verified during the execution monitoring, besides, it exposes relationships and simulates the works in different structural systems to verify the choice of the system. system. The result showed a faster execution, in days worked, in the execution of the mixed metal structure per square meter of construction in relation to the reinforced concrete structure. As for the cost for execution in reinforced concrete it was more viable, that is, the square meter of construction with a lower value. It can also be said that the metallic structure brought positive points in relation to the rationalization of processes, reduction of workforce and waste. Finally, this work contributes to the understanding and decision of choice for structural systems in commercial buildings.
