The structural integrity of the prefabricated concrete shear wall is poor, and stress concentration is likely to occur at the joints, and the deformation is discontinuous, resulting in structural damage or destruction; in order to ensure the integrity of the prefabricated concrete shear wall, prefabricated walls are used. However, this method has problems such as low production efficiency, large environmental pollution, difficulty in ensuring project quality, and large resource consumption. The use of steel-concrete composite shear walls has disadvantages such as high cost and poor fire resistance.
