Strengthening with textile reinforced concrete - reliability based design with imprecise probability
In this paper, the focus is set on the new strengthening technology which bases on the new material textile reinforced concrete (TRC). Thereby, TRC layers are applied on the surface of RC structures. The load-bearing behavior of RC structures with textile strengthening may appropriately described with the multi-reference-plane model (MRM). The purpose of this contribution is to introduce on the one hand the new technology for strengthening damaged and deteriorated RC structures and on the other hand a basically new solution technique to perform a reliability based design. For the latter, an inverse solution of the design problem regarding reliability constraints is suggested. This solution enables the computation of design parameters in dependency of design. The new reliability based design method is applied to a T-beam floor construction in order to design strengthening layers made of textile reinforced concrete. The aim of the investigation is to determine design parameters, which ensure a lifetime of 30 years. The lifetime L is attained, if the fuzzy failure probability exceeds the value of 0.005. Design parameters are the mean value of the randomly distributed tensile strength of the fine grained concrete and the amount of reinforcement.
