The sensibility of the tension softening model and compression model for the simulation of ultra high performance fiber reinforced concrete (UHPFRC) beams is shown. Then, a new concept for a combination of the constitutive models in FEM for UHPFRC is introduced in the present study. In the analysis, the shape of tension softening model for each UHPFRC element becomes depending on the inclination angle of that element. Finally, the advantage of simulation by the proposed technique compared with current FE methods and available test results are demonstrated. |
