Cálculo e verificação de elementos estruturais de um edifício de madeira de acordo com a NBR 7190-1:2022: um estudo de caso

Abstract

The construction industry is one of the most polluting sectors in the world, responsible for over 30% of global carbon dioxide emissions, mainly due to the extraction and processing of traditional materials such as concrete and steel. In contrast, wood, one of the oldest building materials, emerges as an excellent environmental alternative when sustainably harvested. This material requires less energy and produces fewer carbon emissions during its manufacture. Additionally, with modern industrial processing techniques, it is possible to produce robust and durable structural pieces. However, the structural use of wood is still underexplored in Brazil. Thus, this work aims to present the calculation and verification of a four-story residential building using glued laminated timber (GLT). During the development of this project, studies were conducted on the loads, resistance properties, and construction peculiarities of the material. The design follows the ABNT NBR 7190:2022 standard, and computational software was used for structural analysis. The results obtained confirm that GLT wood adequately withstands the demanding forces and meets deformation criteria, proving to be a viable sustainable alternative compared to traditional materials.
