Abstract: Thin shell structures made of Textile Reinforced Concrete (TRC) exhibit a physically non-linear response due to the strain-hardening behavior of the composite. For the simulation of thin walled TRC structures, an anisotropic damage-based material model of a microplane type has been used to reflect the propagation of fine, oriented cracks during the loading. In this paper a method for calibration and validation of a TRC cross section is proposed and demonstrated. After providing a brief summary of key assumptions of the material behavior, the calibration procedure using tensile test data is presented. Then the model is validated by simulation of a test on a TRC vault shell. The comparison is performed both for the load-displacement response and for the observed and calculated distributions of cracks. Finally, the feasibility and validity of the computational model is discussed.
