Języki publikacji
Abstrakty
Przedstawiono wyniki numeryczne dotyczące deterministycznego efektu skali w elementach betonowych o różnych wielkościach, poddanych jednoosiowemu rozciąganiu, jednoosiowemu ściskaniu i zginaniu. Do analizy zastosowano metodę elementów skończonych na bazie sprężysto-plastycznego modelu betonu z nielokalnym osłabieniem.
The paper presents numerical results of a deterministic size effect in concrete elements subject to uniaxial tension and compression, and bending. The calculations are performed with different element sizes. In the analysis, the FE-method on the basis of an elasto-plastic constitutive model for concrete with non-local softening is used.
