In view of the prefabricated shear wall structure, this paper puts forward a prefabricated integrated shear wall structure in which the concrete filled wall with hydrophobic rock wool board partition is poured, produced and installed together with the solid wall limb. Based on the quasi-static test of four concrete double-leg shear walls with the same size, wall limb and reinforcement of coupling beam, the seismic performance of shear walls without filled and integrated whole filled is explored, and the characteristics of failure form, bearing and deformation capacity, stiffness, ductility and energy dissipation capacity of the walls are summarized. The experimental results show that the flexural shear failure occurs in the prefabricated integrated shear wall under horizontal reciprocating load. Compared with the unfilled wall component, the lateral stiffness and shear bearing capacity are obviously improved, and the seismic performance is better at the same time. Based on the ABAQUS analysis software, the quasi-static test results are analyzed by numerical simulation and the hysteresis curve with good agreement is obtained. According to the test results and the numerical simulation, a reasonable filled wall structure scheme for precast integrated concrete shear wall structure is put forward
