Análise do colapso da cobertura em estrutura metálica da Unidade Operacional da PRF em Bataguassu – Estudo de Caso

Abstract

The article explores the importance of metal structures in roofs in civil engineering, highlighting their malleability, efficiency over large spans and applicability in sectors such as industrial constructions. It presents the main and secondary structure, highlighting prefabrication and standardization as key elements. The main focus is to investigate the collapse of the metal roof at the Operational Unit of the Federal Highway Police (PRF) in Bataguassu, in 2023. The objective is to understand the interactions in construction, identify specific causes of the collapse, analyze aggravating factors and provide subsidies for safety guidelines for metallic structures. The case study involves analysis of technical documentation, evaluation of design methods and field inspections. After analyzing the collapsed structure, the complexity of the event is revealed. Lack of regular maintenance and prior inspections are cited as contributing factors. Technical details, such as anchoring, are discussed, highlighting critical points in the collapse. The study highlights the need for more diligent and systematic practices in the safety management and maintenance of metallic structures. It is concluded that the in-depth analysis of the collapse provides support for the prevention of similar events in the future and highlights the importance of compliance with technical standards, such as NBR 8681, in guaranteeing structural stability over time.
