Static and Dynamic Fatigue Strength of Textile Reinforced Concrete

The application of textile reinforced concrete (TRC) is an effective way to strengthen reinforced concrete structures, as already demonstrated in numerous studies, pilot projects and practice- oriented applications. In order to allow the application of TRC for bridge strengthening, further investigations regarding the static and dynamic fatigue strength of the composite material are necessary. To obtain results in those fields first experimental investigations have been conducted. We tested the long term strength for specific periods under defined permanent loads and varying climatic conditions. Subsequently the residual strength of the specimen was determined. Additionally dynamic tests were carried out to prove the fatigue strength of TRC. This paper shows test setups and results of these investigations and provides some perspective to future developments.
