Estudo comparativo de custos entre soluções estruturais de concreto armado para uma arquitetura

Abstract

This paper address a comparative study of final costs for reinforced concrete structures. The accomplishment of the same one was made through the analysis of quantitative of materials and its costs for four models of structures: conventional solid slabs (Model I); ribbed and waffle slabs supported on beams (Model II); lattice girder slabs with expanded polystyrene block (Model III) and ribbed and waffle slabs without support beams (Model IV). The structures were conceived from the architectural design of a building of mixed use. After a bibliographic review, the modeling of the structures was accomplished through using the Eberick 2018 computational tool, under the same criteria of analysis and design, allowing the generation of quantitative materials and cost reporting. Through the analysis of the data provided, it has been verified that Model III presented the lowest cost among the studied structures.
