Reuso de contêiners na construção civil: desafios na análise do comportamento mecânico via método dos elementos finitos e método das faixas finitas

Abstract

Shipping containers have great potential for reuse in civil construction, contributing to sustainability and extending the service life of these products. However, to enable their safe and efficient use, it is essential to understand their structural behavior according to Brazilian civil construction standard regulations. In this sense, this study presents numerical analyses to evaluate the mechanical behavior of these structures in terms of loading and failure modes as well as their prediction of mechanical behavior through Brazilian standard regulations. In this study, a shipping container following the ISO 668 Standard 20’ was evaluated using the finite element method in the ABAQUS software and the finite strip method in the Unconstrained Finite Strip Method (CUFSM) software. Due to the lack of specific Brazilian standards for the design and structural assessment of reused containers, the normative prevision is performed based on the Direct Resistance Method (DRM), according to the ABNT NBR 14762 standard. At the end of the study, the numerical values obtained are compared with the normative criteria to evaluate the applicability of Brazilian standards in the structural analysis of reused containers. The resultsof this research contribute to the development of technical guidelines that assist engineers and designers in the safe and efficient adoption of these elements in civil construction.
