Análise e desenvolvimento de uma ferramenta computacional para verificação de vigas metálicas com seção I segundo a NBR 8800:2024

Abstract

The recent update to ABNT NBR 8800 introduced significant changes to the design criteria for steel structures, directly affecting the calculation routines used in professional practice. In this context, this paper presents the development of a spreadsheet-based computational tool for the structural verification of steel beams in accordance with ABNT NBR 8800:2024. The methodology is based on the study of the current standard, the mathematical modeling of structural verifications, and the automated implementation of calculations. The obtained results were validated through a bibliographic example and comparative analyses, comparing the results with the tool's output. The findings highlight differences in resistance parameters and reinforce the importance of normative updates and the use of a computational tool that provides greater precision and lower possibilities of manual errors, as well as the practical applicability and ease of use of the developed tool. It is concluded that the tool is a viable auxiliary resource for professional practice, noting that the current scarcity of updated technical literature according to the 2024 version limits the performance of more extensive comparisons at this time.
