Estudos de caso sobre avaliação de estruturas de concreto através da utilização de ensaios não destrutivos

Abstract: RESUMOO concreto é parte fundamental dos mais variados projetos de engenharia e, sem duvida, é o elemento estrutural mais utilizado no mundo. Esse fato conduz à necessidade de ferramentas de controle e análise de seu estado de conservação. Muitas das construções em concreto armado que formam a infra-estrutura civil que dão suporte às mais diversas atividades das sociedades modernas estão se aproximando do final de sua vida útil de projeto. Diante desse contexto, existe uma preocupação crescente com a avaliação… Show more

“…The investigation's solution to the problem was to use the ultrasonic pulse velocity test (UPV), in which it was possible to verify the efficiency of this test in solving this problem. The UPV test can be considered one of the most promising tests for evaluating concrete structures [5]. The study shows that UPV tests are sensitive to variations in homogeneity and density, thus providing important data for making decisions about conditions of concrete structures.…”

“…In another study, the authors used the technique to successfully estimate the opening of cracks at different levels of stress [3]. Moreover, the ultrasonic test can also be used to evaluate the profile of thermal damage to concrete structures exposed to high temperatures [4] [5]. This study addresses the method of ultrasonic wave propagation used to understand the propagation pattern of longitudinal and transverse waves in concrete of different compression strengths, undergoing unconfined compression and diametrical compression tests.…”
