Numerical Simulation Of The Bond Behaviour Between High-Performance Textile Reinforced Cement Composites And Concrete During The Double-Lap Shear Test

Book Contribution - Book Chapter Conference Contribution

Textile reinforced cement composites (TRC) are being extensively investigated to be used in buildings and civil infrastructure. Promising application fields are strengthening and retrofitting of existing structures, seismic design, stay-in-place formwork, etc. A critical characteristic for these applications is the bond behaviour between TRC and concrete. Therefore this paper aims to model the complex mechanical behaviour of the interphase between on the one hand textile reinforced cement composites made of Inorganic Phosphate Cement (IPC) reinforced with E glass fibre mats and on the other hand the concrete that is cast on it. The model has to satisfy two conditions: have an acceptable accuracy to enable design calculations and be relatively-easy computable. To achieve this goal, the authors use the cohesive behaviour implemented in finite element software ABAQUS. The model’s necessary parameters (such as bond shear strength, maximal slippage and slippage at maximum shear stress) are identified by performing double lap shear tests. The results of the simulation correspond reasonably well to the data achieved during the laboratory test despite the simplicity of the model, proving its utility for simple stress states. In the future, the model shall be validated on real-scale structures to verify its accuracy in complex stress state.
