The reliability of the connection at the joints of the prefabricated shear walls becomes an important factor affecting the safety of the structure. For the prefabricated shear wall with the vertical joint, enough shear-resisting bearing capacity at the vertical joint needs to be ensured, so that the prefabricated part and the cast-in-place part of the shear wall can work cooperatively to resist bending moment together.
For the prefabricated shear wall with the vertical joints, the joints have certain specificity of shearing resistance. The shear steel bars at the joints are vertical distribution steel bars, and no stirrups are generally arranged near the vertical distribution steel bars, so that the requirement of providing good constraint for concrete cannot be met. The shearing resistance of the vertical distribution reinforcement is influenced by the thickness of the protective layer, so that the effective thickness of the concrete is not enough when the concrete is locally resistant to pressure, and the performance of the reinforcement performance is influenced. The effective thickness of the concrete is mentioned here, not the thickness of the protective layer, because the main function of the effective thickness of the concrete is to resist the extrusion of the reinforcing bars, rather than to prevent the corrosion of the reinforcing bars and to provide sufficient adhesion. Thus, the present document deals with the case where no stirrup is provided
In the prior art, a prefabricated shear wall structure is an assembled integral shear wall structure which is formed by combining prefabricated components and cast-in-place concrete and simulates the stress performance of a cast-in-place structure. The prefabricated shear wall comprises vertical and vertical connections, the connection surface of the prefabricated shear wall is divided into a vertical seam and a vertical seam, the connection method can be divided into dry connection and wet connection, and the difference of the overall structure performance can be caused by the difference of the connection modes.
