Abstract(s)
Com o tempo, as estruturas de construções civis ficam sujeitas a muitos fatores, sejam eles externos ou até mesmo inerentes às próprias estruturas, que influenciam significativamente em suas condições. Para que se possa mantê-las por muito anos, faz-se necessário investigar de forma detalhada seu estado de conservação e para isso, usualmente recorre-se a inspeções estruturais que permitem avaliar seu estado de conservação e com isso adotar procedimentos corretivos necessários. Entretanto, alguns tipos de estruturas tais como torres de telecomunicações, pontes, plataformas de petróleo offshore, torres de transmissão de energia, torres produtoras de energia eólica e outras, apresentam dificuldade no acesso para que o inspetor possa realizar suas tarefas. Através deste trabalho, avalia-se a contribuição da utilização de Veículos Aéreos Não Tripulados (VANT) ou drones em atividades de inspeção dinâmica. São apresentadas diferentes técnicas de inspeção para obter deslocamentos estruturais utilizando como exemplo de pesquisa prática a inspeção da Torre do Monte da Virgem, em Portugal, recorrendo à utilização de drones e processamento dos dados através do software MATLAB. O trabalho apresentou resultados muito promissores, sendo a utilização de drones de grande valia, mas apresentou também algumas limitações que são discutidas.
Over time, civil construction structures are subject to many factors, whether external or even inherent to the structures themselves, that significantly influence their conditions. In order to be able to maintain them for many years, it is necessary to investigate in detail their state of conservation and, for this, it is usually resorted to structural inspections that allow the assessment of their state of conservation and thus adopt necessary corrective procedures. However, some types of structures such as telecommunication towers, bridges, offshore oil rigs, power transmission towers, wind power towers, and others, present difficult access for the inspector to perform his tasks. Through this work, the contribution of the use of Unmanned Aerial Vehicles (UAV) or drones in dynamic inspection activities is evaluated. Through it, different inspection techniques are presented to obtain structural displacements, the practical inspection survey of the Monte da Virgem Tower in Portugal, with drone and data processing through MATLAB software, is presented as an example. The results of the project presented were promising though some limitations, which are also discussed, were detected.
