The X-direction frame, which is composed of Y-shear wall and floor, is involved in the anti-side and floor of the X-way shear wall structure by the simplified model. It should be designed and strengthened as a bending member in the anti-side frame system. In this paper, the internal force of the floor design and the conventional design is compared with that of the conventional design. The floor is only considered in the vertical structure in combination with the performance target. In addition, the relationship between the shear rate of the outer wall or the shear wall and the actual model can be verified with the results of the simplified model analysis
