Fiber reinforced polymer (FRP) textile, as the continuous reinforcement of multi-scale fiber reinforced cementitious composite (MSFRC), is expected to be widely applied due to the high strength, lightness, anti-corrosion and ease of installation. In this work, the unique features of FRP textile, characterized by initial delayed stiffness and strength efficiency, are investigated thoroughly. First, the direct tensile tests, comprising FRP textile and MSFRC plate specimens, are performed by varying the number of the textile ribs and layers. On this basis, an analytical approach for FRP textile is proposed based on the digital geometric model and Monte Carlo simulation. The considered distributions of textile properties include the stochastic slacks and strengths of different ribs. Then, a good agreement can be found between the experiments and the simulations. Finally, the bilinear model of FRP textile is further developed using the proposed model to serve as a basis for the reliable structural design.

纤维增强聚合物（FRP）织物作为多尺度纤维增强水泥基复合材料（MSFRC）的连续增强体，由于具有高强度、轻质、耐腐蚀、易于安装等优点，有望得到广泛应用。在这项工作中，彻底研究了玻璃钢织物的独特特性，即初始延迟刚度和强度效率。首先，通过改变织物肋和层的数量来进行直接拉伸测试，包括 FRP 织物和 MSFRC 板样本。在此基础上，提出了一种基于数字几何模型和蒙特卡罗模拟的FRP织物分析方法。考虑的纺织品特性分布包括不同罗纹的随机松弛和强度。然后，实验和模拟之间可以找到很好的一致性。最后，使用所提出的模型进一步开发了 FRP 织物的双线性模型，作为可靠结构设计的基础。
