Combined shear wall internally provided with fiber-reinforced polymer tubes for constraining metallic framework concrete

The invention discloses a combined shear wall internally provided with fiber-reinforced polymer tubes for constraining metallic framework concrete. The fiber-reinforced polymer tubes are arranged in the shear wall. Metallic frameworks are arranged in the fiber-reinforced polymer tubes. The portions between the fiber-reinforced polymer tubes and the metallic frameworks are filled with concrete. According to the combined shear wall, the characteristics that the concrete constrained by a fiber-reinforced polymer is high in strength and good in deformation capacity and meanwhile has the remarkable two-order rigidity are used, the FRP tubes are arranged on the positions where a wall body deforms or the stress is larger in a constrained manner, such as one or more of the wall end, an intersecting position of two wall columns and intersecting positions of multiple wall columns, the metallic frameworks are embedded in the concrete constrained by the fiber-reinforced polymer tubes, and the metallic framework concrete constrained by the fiber-reinforced polymer is formed. The combined shear wall has the beneficial effects that deformation capacity is high, and the concrete in the stressed area cannot be crushed easily and further has the remarkable two-order rigidity so that the wall body can have the self-centering function when large deformation is generated.
