Abstract: Textile reinforced concrete (TRC) represents a proper material for retrofitting and strengthening of aged or damaged reinforced concrete structures. The practical application of TRC strengthening presupposes a numerical prediction of the improved structural behavior including the material behavior of the TRC strengthening layer. Data and numerical models for predicting the long-term behavior of TRC, however, are not available to a sufficient amount and reliability. Long-term tests with small TRC specimens under uniaxial tension were investigated under sustained loading for up to six months. The test results provide some insight into long-term performance of TRC. But experiments covering time periods with relevance to structural life-time, however, are not realizable. That is, a numerical prognosis method is required to infer long-term behavior based on the experiments. In view of the complexity of the problem and still unavailable physical models, a model-free prognosis strategy on the basis of neural network techniques incorporating experiences from stochastic process simulation is pursued.
