This application relates to a prefabricated composite shear wall based on a steel pipe structure, comprising two parallel composite slabs and an energy-dissipating steel-concrete composite member. A cavity is provided between the composite slabs to accommodate the energy-dissipating steel-concrete composite member. The energy-dissipating steel-concrete composite member comprises symmetrically arranged steel-concrete composite components, each consisting of four diagonally connected steel-concrete composite members. These components are prismatic in shape, with their edges abutting against beam members. In this application, when the energy-dissipating steel-concrete composite member is subjected to seismic forces, the eight diagonally connected steel-concrete composite members of the energy-dissipating steel pipe component collectively dissipate energy through bending, thereby absorbing some of the seismic energy. Furthermore, the strong load-bearing capacity of the energy-dissipating steel pipe component reinforces the weak points of the shear wall, reducing the occurrence of damage or failure of some shear wall components. This allows the components of the shear wall to work together to resist seismic forces, improving the overall seismic performance of the shear wall.
