چکیده مقاله:

Textile-reinforced mortar, TRM for short, is an emerging and valuable composite material for constructing civil structures. Light weight, high resistance against corrosion, strengthening in the desired direction of the structure, and low thickness are advantageous for TRMs. TRM's experimental characterization is very costly and time-consuming due to numerous invariant, which affects the mechanical properties of TRMs. Therefore, developing analytical and numerical models is necessary to predict TRM behavior in different textile and mortar configuration. In this contribution, a micromechanical model is presented for modeling the tensile behavior of TRMs. A two-scale micromechanical model is used in the current model to predict TRM's elastic behavior subjected to tensile load. Also, Shear-lag theory is used for the prediction of TRM behavior in the cracked phase. The results show that the proposed model can predict the whole TRM response to tensile load.
