Concrete is extremely vulnerable against impact loading due to its low tensile strength and pronounced brittleness. The application of thin strengthening layers, containing Textile Reinforced (TRC) Strain-Hardening Cement-based Composites (SHCCs) in a ductile cement-based composite, promising solution enhance the resistance existing concrete structures. Three-dimensional (3D) textile structures exhibit numerous advantages over two-dimensional (2D) ones, most importantly higher shear, bending energy absorption capacity, hence, appear be instrumental providing sufficient reinforcement target layers. However, design variability optimization possibility available 3D are restricted. This paper presents development novel textile-based truss that can overcome these limitations. On basis woven cellular structures, innovative pyramidal with favorable load-bearing capacity as well notable capability developed successfully realized. To investigate feasibility efficacy, composite consisting SHCC newly prepared tested under high-speed transversal loading. experimental results show highly compatible SHCC, significantly enhances resistance. Furthermore, reinforced structure remarkably outperforms 2D carbon reinforcing approved for commercial use.
