A INFLUÊNCIA DAS AÇÕES DOS SISTEMAS DE VEDAÇÃO VERTICAL NO DIMENSIONAMENTO ESTRUTURAL: uma comparação entre a alvenaria de bloco cerâmico, o light steel frame e o drywall

Abstract

The construction industry in Brazil has always been considered traditional and conservative. Important measures taken since the 1990s to liberalize and open the economy have significantly changing this perspective. The current scenario requires related professionals to make more efficient works, environmentally sustainable and at competitive costs. To meet this demand, vertical sealing has emerged as one of the most innovative building systems in the market. More and more builders have moved away from the traditional ceramic block masonry system. In this context, it is critical to understand how the emerging buildings systems interact with traditional systems. This study aims to analyze the sealing systems: ceramic blocks masonry, light steel frame and drywall, to later be verified the influence of the actions of these systems in the project of structures in reinforced concrete. A case study was prepared about a 10 floor building where three models with different compositions of vertical sealings have been applied. It was verified that vertical sealing systems have a great influence on the design of structures, including the Z-Range parameters. However, the reductions found in material quantities and final loads are not proportional to the reductions coming from the direct actions of the different types of vertical sealings of studied.
