<P>PROBLEM TO BE SOLVED: To provide a composite structure, a segment, and a method of manufacturing a segment, capable of sufficiently enhancing reinforcement effect for various stress states to reduce material costs, processing labor, and processing costs, while securing filling of concrete. <P>SOLUTION: A shear reinforcement 4 in a segment 1 is wound to bridge a first main reinforcement 31 and a second main reinforcement 32 from one reinforcement plate 5 to another reinforcement plate 5 with a gradient. The shear reinforcement 4 is composed of a first and a second shear reinforcements 41 and 42 crossing each other to form an X-shaped configuration. Consequently, the shear reinforcement 4 can be effectively arranged with respect to both directions toward a tension side and a compression diagonal side of a truss mechanism formed between the reinforcement plates 5, resulting in reducing material costs, processing labor, and processing costs, while securing quality of manufacture with enhanced filling of concrete 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
