This article deals with the issue of the bond between concrete and reinforcement. The bond is crucial for reinforced concrete elements because it is possible to transfer forces (stresses) from concrete to the reinforcement. Basic information related to the cooperation of concrete and rebars was recalled in the article. Selected issues concerning theoretical and numerical analysis as well as experiments...
W artykule zostały przedstawione wyniki badań doświadczalnych wpływu szokowego ochładzania po pożarze na przyczepność stali zbrojeniowej żebrowanej gatunku B500SP oraz BSt500S do betonu C30/37. Badania realizowano w ramach projektu: „Innowacyjne środki i efektywne metody poprawy bezpieczeństwa i trwałości obiektów budowlanych i infrastruktury transportowej w strategii zrównoważonego rozwoju” POIG...
Research on bond under cyclic loading is usually performed using specimens of a very short bond length. Results of such a research show very often that bond can be completely destroyed. According to that, most standards demand some extra anchorage length of steel bars. Different results were obtained by the author from experiments on long specimens under eccentric tension. If a concrete member is...
