Based on the engineering design, the deformation characteristics of the high-rise concrete frame shear wall structure are analyzed. The formulae for calculating the yield strength and ultimate strength of the structural components considering the effects of the edge elements and reinforcement are derived. The elastic structure and elasto-plastic time history calculation of multi-wave input seismic response are carried out on the actual structure, and the effects of seismic wave, elastic parameters of structural components on deformation analysis are discussed. In addition, a simplified calculation method for determining the reasonable number of floor shear walls and the section size of frame pillars using the method of inter-layer displacement of the weak layer of the control structure was deduced. The calculation formulas for the stiffness of the structural layer and the shear strength of the layer were proposed and adopted through the actual project. The secondary design of the deformation control and verification, investigated the rationality of the method, indicating that the calculation accuracy meets the needs of engineering design.
