dc.description.abstractThis Master thesis is about analysis of Ultra-high performance fibre reinforced concrete (UHPFRC) beams with the help of the Finite Element Analysis software ANSYS. The research question and the operational questions are: How can we analyse UHPFRC beams with the help of ANSYS? How does the built in concrete material model in ANSYS work? How can the concrete material model in ANSYS simulate behaviour of UHPFRC beams? The approach used to answer the questions is based on the hypothetico-deductive method. Hypotheses are built from the theoretical framework and tested in ANSYS. The results from the tests are used to refine the theory, the hypotheses and the tests. The concrete material model in ANSYS is based on K. J. William and E. P. Warnke’s 5-parameter constitutive model for triaxial behaviour of concrete. This theory is naturally central to the work in this thesis. The results from the tests in ANSYS show that the concrete model can predict the behaviour of relatively small UHPFRC beams with flexural- and shear reinforcement. If the beams are without reinforcement, the model cannot accurately predict the behaviour of the material. By combining the Drucker-Prager plasticity model to the concrete model in ANSYS, the behaviour improved. To further increase the accuracy of the models a more sophisticated hardening rule is needed. The concrete material model in ANSYS is found to be too inflexible in this regard.nb_NO
