Elaboração de planilha automatizada para dimensionamento de pilares de aço submetidos a compressão simples

Abstract

The Brazilian civil construction industry has increasingly adopted steel structure systems, requiring agility and precision in design from structural engineers. Columns, crucial elements of the structural assembly, are subject to instability phenomena whose verification is repetitive, making it susceptible to errors. Given the current scenario, this work aimed to build an automated spreadsheet on the Microsoft Excel platform for the verification and design of steel columns subjected to simple compression, in accordance with NBR 8800 (ABNT, 2024). The methodology consisted of three stages: a bibliographic survey of calculation procedures; the construction of the tool, based on data organization and usability; and validation. The software was implemented with a database of rolled profiles and an intuitive interface designed to prevent input errors. For the tool verification, four application examples were used: three from classical literature, recalculated according to the current standard, and one developed by the author for the verification of slender profiles. The results showed high concordance, demonstrating the precision of the implemented algorithm. The developed software meets the demands for agility and reliability, proving to be a didactic and practical tool for technical and academic use in steel structure projects.
