Analysis of Textile Reinforced Concrete at thecro-level

摘要

To increase knowledge on the load carrying behaviour of textile reinforced concrete(TRC), simulations are important to complement experimental investigations. Due to the het-erogeneous structure of TRC, different damage mechanisms at different scales are found. Sincenot all details can be represented in one model, different modelling levels have to be consid-ered. This paper focuses on the modelling of TRC at the micro-scale and therefore particularlyat the experimental and theoretical determination of the material, bond and micro-structuralproperties needed for the modelling. The consideration of fatigue damage due to cyclic and sus-tained loading, which is indispensable for the design of structural members, enhances the com-plexity of the material and bond laws. To verify the developed model, yarn pullout tests undermonotonically increasing, cyclic and sustained loading with additional experimental techniquesfor the monitoring of the filament ruptures during the tests are scheduled.
