Abstrakty

W artykule, posiadającym charakter studialny, przedstawiono zagadnienie efektu skali w badaniach elementów betonowych. Problem efektu skali, występujący w różnych stanach naprężeń, opisano w sposób wieloaspektowy w oparciu o kryteria statystyczne i energetyczne. Pozwoliło to na uwypuklenie jego złożoności i podkreślenie różnorodności czynników mających nań wpływ. Autorki zwracają uwagę, że informacji dotyczących wpływu efektu skali w odniesieniu do betonowych elementów monolitycznych jest w literaturze wiele, natomiast odczuwalny jest brak prac omawiających wytrzymałość elementów, w których występuje styk betonu starego z nowym.

The review of the problem of size effect in the case of concrete elements on the basis of recent papers was discussed. The results of these papers show the complexity and diversity of factors causing the size effect. Significant influence of specimens size on test results cannot be neglected in evaluation of the strength of concrete and load bearing capacity of the structure. There is a lot of data concerning the size effect in the case of monolithic concrete elements, however, there is a lack of papers concerning this effect regarding the strength of the bond of interface between two concretes, placed in some time interval.
