Abstract

The evaluation of fiber reinforced sprayed concrete is conducted by plate test procedure according to OENORM EN 14488-5. With the test facility developed by the chair of subsurface engineering, a number of tests were performed. The target of the tests was to asses the influence of imperfections of the samples, support and test conditions on the energy absorption capacity. In this thesis the plate test is simulated with the FE-Program ABAQUS, utilizing the 'Concrete Damage Plasticity' (CDP) material model. An analysis is performed to describe the impact of the modeling technique and the numerical imperfections on the crack development.
