| Based on the distortion characteristic of the frame-shear wall structure cooperation work, using the member-story model dynamic program, this paper analyze the frame-shear wall structure model with variable shear wall height. The EL- Centro 1940 NS ground acceleration record is inputted. Contrasting the result, include the free vibration frequency, maximal displacement response, floor displacement, floor shear force, to the result from the shaking table, it has a good agreement with each other. It is shown that the member-story model dynamic program is accurate and effectual. Analyzing the different cases that the frame-shear wall structure model has differ height and stiffness shear wall, the paper conclude that the shear wall should be interrupted above the structure distortion inflection. At the same time, the model the transform floor stiffness ratio is confirmed and taken as the criterion to determining the transform floor is reinforced or not. The different cases of two engineering with variable interrupting stiffness are analyzed. Contrasting two cases of interrupted the shear wall above/below the inflection, the result show that the structure shear wall interrupted above the inflection has high security and aseismatic capability. The conclusion is right proved. Interrupting the shear wall according to the intensity, field, and the plane collocation of the wall, the dynamic characteristic of the frame-shear wall structure is closed to that of the structure with the shear wall in the entire structure. The distortions are also smaller than original structure and meet with the requirement of the codes. So, the frame-shear wall structure with the shear wall stiffness interruption is a feasible and efficient project. The reasonable transform floor stiffness ratio range and the chosen principle are summarized. Finally, based on the analysis, the practical design suggestion and notice questions are also presented.
