Analysis of textile reinforced concrete at the micro-level

Abstract

To increase knowledge on the load carrying behaviour of textile reinforced concrete (TRC), simulations are important to complement experimental investigations. Due to the heterogeneous structure of TRC, different damage mechanisms at different scales are found. Since not all details can be represented in one model, different modelling levels have to be considered. This paper focuses on the modelling of TRC at the micro-scale and therefore particularly at the experimental and theoretical determination of the material, bond and micro-structural properties needed for the modelling. The consideration of fatigue damage due to cyclic and sustained loading, which is indispensable for the design of structural members, enhances the complexity of the material and bond laws. To verify the developed model, yarn pullout tests under monotonically increasing, cyclic and sustained loading with additional experimental techniques for the monitoring of the filament ruptures during the tests are scheduled.
