Detection of rebar anchorage length using elastic wave propagation

Abstract: W pracy przedstawiono wstępne wyniki badań eksperymentalnych i obliczeń numerycznych mających na celu określenie możliwości oceny stanu zakotwienia prę-ta stalowego w materiale kompozytowym typu zaprawa. Badanym obiektem był pręt stalowy osadzony w zaprawie o kształcie prostopadłościanu. Analizie poddano pręt stalowy otoczony zaprawą na trzech różnych długościach oraz pręt stalowy swobodny. W jednym z modeli na pewnym odcinku dokonano uszkodzenia w postaci braku współpracy między zaprawą a stalowym prętem. Do … Show more

“…While guided wave propagation-based techniques have been applied for many years in steel, aluminum and composite structures (e.g., Jurek et al, 2007;Rucka 2010;Żak et al, 2012), currently there is a considerable and growing interest in the use of guided waves for the evaluation of reinforced concrete structures (e.g. Chróscielewski et al, 2012;Rucka and Wilde, 2013) or rock bolt structures (e.g., Beard and Lowe, 2003;Wang et al, 2009;Zou et al, 2010;Rucka, 2013;Rucka and Zima, 2014). The methods based on propagation of ultrasonic waves are also used to assess the degree of corrosion of steel encased in concrete (Ervin et al, 2009, Lu et al, 2013 or detection of locations where delamination occurred at the border of concrete-steel (Na et al, 2003).…”
