Journal of the institution of engineers (India): Series ASummary: Thin-walled constructions for various applications are realized using textile-reinforced concrete (TRC), mainly due to the non-corrosiveness of the textile reinforcement. By proper selection of matrix and textiles, TRC is able to withstand high compressive and tensile loads in a structure. For the application of TRC in highly stressed structures, it is essential to evaluate the local and global response performance of TRC. Based on this requirement, a macro-modelling methodology for finite element analysis of TRC products is developed in this study. Investigations are carried out on the development of cylindrical- and rectangular-shaped TRC tanks. Concrete damaged plasticity model has been used for the constitutive modelling of TRC. A generalized model that represents TRC matrix has been used to derive the damage parameters under compression. A new constitutive model has been proposed for TRC, to represent the tensile behaviour and subsequently to derive the damage parameters in tension. The model has been validated with the experimental response of TRC. The global and local behaviour of TRC tanks modelled implementing the macro-modelling methodology has been analysed and discussed based on the analysis results. The proposed numerical analysis method demonstrated also further opens up the possibility of adopting the proposed method to various TRC product applications.

Thin-walled constructions for various applications are realized using textile-reinforced concrete (TRC), mainly due to the non-corrosiveness of the textile reinforcement. By proper selection of matrix and textiles, TRC is able to withstand high compressive and tensile loads in a structure. For the application of TRC in highly stressed structures, it is essential to evaluate the local and global response performance of TRC. Based on this requirement, a macro-modelling methodology for finite element analysis of TRC products is developed in this study. Investigations are carried out on the development of cylindrical- and rectangular-shaped TRC tanks. Concrete damaged plasticity model has been used for the constitutive modelling of TRC. A generalized model that represents TRC matrix has been used to derive the damage parameters under compression. A new constitutive model has been proposed for TRC, to represent the tensile behaviour and subsequently to derive the damage parameters in tension. The model has been validated with the experimental response of TRC. The global and local behaviour of TRC tanks modelled implementing the macro-modelling methodology has been analysed and discussed based on the analysis results. The proposed numerical analysis method demonstrated also further opens up the possibility of adopting the proposed method to various TRC product applications.
