Experimental and numerical investigation of tensile behaviour of glass textile-reinforced concrete composite

Abstract

Textile-reinforced concrete (TRC) composite is increasingly used in infrastructure engineering. In the case of reinforcing/strengthening degraded structures, this composite material ensures more sustainable and environmentally friendly development criteria than fibre-reinforced polymer (FRP) composite materials. This paper presents experimental and numerical results of the tensile behaviour of glass textile-reinforced concrete. Glass textile and fine-grained concrete were tested separately to identify the tensile or compressive strengths and Young’s modulus. These mechanical characteristics were also used as the input parameters for the finite element model to predict the tensile behaviour of glass TRC samples. This model was based on the cracking failure model for fine-grained concrete and the linear elastic model for the glass textile. The numerical model results were compared with the experiment obtained from the TRC samples. Experimental results and the numerical model were analyzed and discussed to find the agreement of the numerical model.
