In the actual frame structure design, the filler wall is generally regarded as a non-structural member for treatment, and the additional rigidity of the filler wall to the main structure is not considered, and only a certain reduction is made on the structure period. In actual construction, however, extensive testing has shown that the presence of infilled walls significantly increases the load bearing capacity and stiffness of the frame structure. When the frame structure bears the earthquake action, the infilled wall and the frame structure are a common stressed system.

In addition, the damping wall board also needs to be capable of reducing the additional rigidity of the filler wall to the frame structure, and the damping layer can play a role in friction hysteresis energy dissipation through relative dislocation of the wall board units.
