Análise e dimensionamento de paredes de concreto moldado in loco para habitações sociais

Abstract

The construction industry is constantly changing, whether due to geographical, environmental, or economic reasons, seeking ways to optimize its processes. In Brazil, there is still a predominance of the masonry block wall construction system, either due to the ease of finding materials or its labor force, which does not require specialization and is consequently cheaper. The concrete wall system appears as an alternative to conventional construction, consisting of forms that finish the walls and slabs, which are concreted all at once, without beams or columns. The following work consists of a study on the concrete wall system and its sizing method focused on social housing, considering a 50m2 residence and based mainly on NBR 16055:2022. At the end of the system analysis, it was possible to size the main reinforcements, being welded Q159 screens and reinforcement bars between openings, as well as demonstrating its detailing.
