The failure mechanisms of textile reinforced concrete (TRC), which is a composite of bundles of long fibers and fine-grained concrete, are complex. Even after fracture of the constituents AR-glass and concrete the bond behavior has an important influence on the effective material behavior of the composite. Therefore, any realistic numerical simulation of the TRC composite behavior requires an accurate model of the bond between the reinforcement and the matrix as well as between the filaments within the roving. This paper summarizes the main characteristics of TRC. Further, an adhesive cross linkage approach is used to model the different bond aspects within the roving. In addition to this analytical approach some numerical simulations are presented.
