Análise das principais patologias em estruturas metálicas: estudo de caso em três obras em Anápolis-GO

Abstract

Pathological manifestations in metal structures, such as assembly failures, inadequate design, painting problems, corrosion and failures in metal connections, have become increasingly frequent in works that use this type of structure. Several questions can be raised about this, such as the lack or insufficiency of detailing in the projects, planning failures, use of low-quality materials and lack of specialization of the workforce. In civil engineering, pathology refers to the study of the symptoms, causes and origins of anomalies that can affect the useful life of a building. The main objective of this case study was to identify the pathological manifestations present in works with metal structures in the city of Anápolis-GO, analyze their possible causes and propose repair and mitigation strategies. To this end, a survey of the anomalies found was carried out through photographs and data collection, in addition to a bibliographic review. The main pathological manifestations identified were paint failures, assembly failures, design failures, corrosion and failures in metal connections, caused by flaws in the design, in the execution of the work and by the use of low-quality and low-resistance materials. The lack of adequate qualifications of the workforce was also a contributing factor to these problems. At the end of this research, it was possible to provide a complete diagnosis of the pathological manifestations observed, identify their causes and propose methods for correction and future prevention. The problems identified could have been avoided if all stages of the project in each case study had been carried out by a qualified workforce.
