There has been a rising interest in utilising textile reinforcement such as carbon tows in constructing concrete components to enhance the performance of conventional reinforced concrete. Textile-reinforced concrete (TRC) has been used as a construction material mostly as primary reinforcement. However, the structural performance of TRC members has not been investigated in depth. Therefore, to better understand TRC beams’ behaviour under bending load, a widespread experimental investigation was conducted. The results of tensile stress-strain, load-deflection, moment-curvature, and tension stiffening behaviours of TRC beams were associated with conventional steel-reinforced concrete (SRC) beams. In this study, the four-point bending and tensile strength tests were performed. The results revealed that, unlike the stress-strain behaviour observed in steel, textile reinforcement does not exhibit yielding strain. The flexural behaviour of TRC beams shows no similarity to that of SRC beams at postcracking formation. Besides, the moment capacity and tension stiffening of TRC beams were found 56% and 7 times higher than those of SRC beams, respectively. Therefore, in light of these results, it can be said that TRC beams behaviour differs from that of SRC beams.

纤维增强混凝土梁与钢筋混凝土梁的性能

在构造混凝土构件以增强常规钢筋混凝土的性能时，人们越来越关注利用诸如碳纤维束之类的织物加强材料。纺织增强混凝土（TRC）已被用作建筑材料，主要用作主要增强材料。但是，尚未深入研究TRC构件的结构性能。因此，为了更好地了解TRC梁在弯曲载荷下的行为，进行了广泛的实验研究。TRC梁的拉伸应力-应变，载荷-挠度，弯矩曲率和拉伸刚度行为的结果与常规的钢筋混凝土（SRC）梁有关。在这项研究中，进行了四点弯曲和拉伸强度测试。结果表明，与在钢中观察到的应力应变行为不同，织物增强材料不会表现出屈服应变。TRC梁的挠曲特性在裂后形成中与SRC梁没有相似之处。此外，TRC梁的弯矩承载力和抗拉刚度分别比SRC梁高56％和7倍。因此，根据这些结果，可以说TRC束的行为不同于SRC束的行为。
