3D Smeared Fracture FE-Analysis of Concrete Structures

ABSTRACT In the present paper, a finite element code based on the microplane model for concrete is used for the analysis of recently proposed EDF benchmark examples. Four numerical cased are considered: resonnse of concrete constitutive law under uniaxial cyclic loading, mixed tension-shear test (Willam's test) at the constitutive level, shear failure of reinforced concrete beam with and without shear reinforcement and mixed mode failure (Nooru-Mohamed test). In the numerical studies the three-dimensional eight node solid finite elements with eight integration points are employed. As a regularisation procedure the crack band method is used. The numerical results are compared with available experimental data that were only partly known before the study was performed.
